What unique challenges do you face engaging or addressing the needs of your students?

Many of the students I teach face challenges including poverty, homelessness, and learning English as a second language. This year, in particular, has been extremely difficult for all of us dealing with the pandemic and distance learning. As a teacher, I have had to find ways to make sure that my students are engaged in scientific inquiry and have access to resources and materials while learning remotely. This begins and ends with a conscious effort to acknowledge that kids are struggling with this online format and carving out time in every single class to provide the socio-emotional support they have come to expect from a classroom environment. Before we dive into content, this means making time for check-ins and updates. In any in-person classroom, we carve out time to get to know each other, and being online should not diminish that. Of course, as we all learned this year, easier said than done.

Social isolation is another factor that contributes to the challenges of distance learning. Even though students see their peers virtually, it is often difficult for them to open up and talk as freely as they would if they were in a physical classroom. So I have had to find ways to make sure that my students are comfortable with engaging in a virtual setting by allowing them opportunities to talk and collaborate with each other online.

Lessons for Educators

Bring NASA STEM into the classroom with standards-aligned lessons exploring Earth, Mars, and worlds beyond.

Using breakout sessions was difficult at first, because the students were very self-conscious about speaking to each other on screen and were reluctant to share ideas. So every day, we spent the first few minutes in each class just talking to each other through text-based chat to get them socializing and feeling more comfortable with this new way of interacting. Now they are more comfortable engaging in scientific inquiry with each other and have meaningful discussions to expand their learning. It is not the same as having them physically perform labs together in class but things are definitely improving.

Another challenge has been providing all of my students with access to resources and materials that allow them to simulate a laboratory experience at home. I have been pleasantly surprised at the wealth of resources I have available to me as a teacher to provide virtual labs and activities to my students. Whether it is virtual demonstrations and simulations or scientific investigations that require simple materials that students can find around the house, we have been very resourceful so we can give students the best experience possible through distance learning. Promoting lab science with home supplies has been instrumental in student engagement, as they really get to explore in their own context, expressing themselves creatively with what they have at their disposal instead of being provided the materials.

How have you used lessons from NASA and JPL to keep students engaged while teaching in person and remotely?

I have always been fascinated by outer space and have loved sci-fi TV shows and movies since I was very young. So as a teacher, I was so excited to discover ways to use my love of astronomy to engage my students.

When I discovered NASA and JPL's resources and lessons, I went through them like a kid in a candy store. I found so many different activities that I could adapt to use in my own classroom. Over the past few years, I have used several JPL Education lessons and modified and extended them for my students.

While remote instruction has had its challenges, Ms. Windsom found that getting students to strike up conversations via chat at the start of class made students more willing to collaborate and share their designs for projects usually done in the classroom, like these cardboard rovers.

For example, I took JPL's Touchdown lesson and allowed students to create their own planetary lander using materials they could find around their home. I challenged them to create a way to quantify how much impact the touchdown would have on the "astronauts" in their lander. Some students used balls of play dough as their astronauts, and quantified the impact by measuring the dents made in the play dough by paper clips that they had placed on the "seats" of their lander.

Another example was when I combined the Soda-Straw Rocket and Stomp Rockets lessons. I had my students create a straw-stomp rocket to investigate how changing the angle of the rocket launch could have an effect on the distance the rocket traveled.

My students also had the opportunity to participate in engineering activities with JPL and college students from Pasadena City College. The impact that this had on my students was profound and long-lasting. It was inspiring for my students to hear from NASA scientists and student role-models who encouraged them to pursue careers in science, engineering, and technology.

Ms. Wisdom says that pesentations from STEM professionals go a long way toward engaging students, so she has made them a fixture in her classes – whether in person or remote. Image courtesy: Shirley Yong and Malak Kawtharani | + Expand image

How have students reacted to these lessons?

The biggest payoff for me was seeing students envision themselves as NASA scientists. They learned to collaborate with each other, learn from each other, and challenge each other. They were able to experience every step of the engineering process firsthand. They were actively involved in designing, building, and testing their rockets and landers. They could also gather information from watching other students revise and improve their designs. Learning from each other was so much fun for them. As a teacher, watching my students strengthen their critical thinking, practical engineering, and problem-solving skills is one of the best parts of my job.

You switched from teaching middle school to teaching high school this year. How are you thinking about incorporating NASA resources into lessons for older students?

Growing up, I loved how the technology that I saw in the sci-fi shows I watched as a kid eventually made its way into our reality. I am always amazed at how NASA scientists push the boundaries of technology development and are only limited by the scope of their imagination.

As a high school biology teacher, I'm looking forward to having my students examine the ways that space technology is being used to help humans improve the health of the planet. Investigating climate change and the ecological impact humans have on the environment is so important. Looking at how NASA gathers data to better understand climate change is especially critical at this time because my students' generation is going to play a pivotal role in developing technologies for improving life on Earth. I'm looking forward to continuing to use JPL Education resources to help my students prepare for that challenge.

In the News

On Feb. 18, NASA's Perseverance Mars rover is scheduled to touch down on the Red Planet after a seven-month flight from Earth. Only the fifth rover to land on the planet, Perseverance represents a giant leap forward in our scientific and technological capabilities for exploring Mars and the possibility that life may have once existed on the Red Planet.

Here, you will:

• Meet the Perseverance Mars rover and find out what it's designed to do once it lands.
• Find information about how to tune into and participate in live events leading up to and on landing day.
• Learn about an exciting opportunity to get your classroom, educational organization, or household involved with the Mission to Mars Student Challenge.

Why It's Important

You might be wondering, "Isn't there already a rover on Mars?” The answer is yes! The Curiosity rover landed on Mars in 2012 and has spent its time on the Red Planet making fascinating discoveries about the planet's geology and environment – setting the stage for Perseverance. So, why send another rover to Mars? The lessons we’ve learned from Curiosity coupled with advancements in technology over the last decade are allowing us to take the next big steps in our exploration of Mars, including looking for signs of ancient microbial life, collecting rock samples to bring to Earth one day, and setting the stage for a potential future human mission to the Red Planet.

More specifically, the Perseverance Mars rover has four science objectives:

• Identify past environments on Mars that could have supported microbial life
• Seek signs of ancient microbial life within the rocks and soil using a new suite of scientific instruments
• Collect rock samples of interest to be stored on the surface for possible return by future missions
• Pave the way for human exploration beyond the Moon

With these science objectives in mind, let's take a look at how the mission is designed to achieve these goals – from its science-rich landing site, Jezero Crater, to its suite of onboard tools and technology.

How It Works

Follow the Water

The black oval indicates the area in which the rover will touch down, also called a landing ellipse. Image Credit: NASA JPL/Caltech/MSSS/JHU-APL/ESA | › Full image and caption

While present-day Mars is a cold, barren planet, science suggests that it was once very similar to Earth. The presence of clay, dried rivers and lakes, and minerals that formed in the presence of water provide extensive evidence that Mars once had flowing water at its surface. As a result, a mission looking for signs of ancient life, also known as biosignatures, should naturally follow that water. That’s because water represents the essential ingredient for life as we know it on Earth, and it can host a wide variety of organisms.

This is what makes Perseverance's landing site in Jezero Crater such a compelling location for scientific exploration. The crater was originally formed by an ancient meteorite impact about 3.8 billion years ago, and it sits within an even larger, older impact basin. The crater also appears to have once been home to an ancient lake fed by a river that formed the delta where Perseverance will begin its exploration, by exploring the foot of the river delta.

Tools of the Trade

Once Perseverance has successfully landed, it will begin its scientific exploration with the assistance of an array of tools, also known as science instruments.

This artist's concept shows the various science tools, or instruments, onboard the rover. Image credit: NASA/JPL-Caltech | › Learn more about the rover's science instruments

Like its predecessor, Perseverance will have a number of cameras – 23, in fact! – serving as the eyes of the rover for scientists and engineers back on Earth. Nine of these cameras are dedicated to mobility, or tracking the rover's movements; six will capture images and videos as the rover travels through the Martian atmosphere down to the surface, a process known as entry, descent, and landing; and seven are part of the science instrumentation.

PIXL can make slow, precise movements to point at specific parts of a rock's surface so the instrument's X-ray can discover where – and in what quantity – chemicals are distributed in a given sample.

Navcam, located on the mast (or "head") of the rover, will capture images to help engineers control the rover. Meanwhile, Mastcam-Z, also on the rover’s mast, can zoom in, focus, and take 3D color pictures and video at high speed to allow detailed examination of distant objects. A third camera, Supercam, fires a small laser burst to excite compounds on the surface and determine their composition using spectroscopy. Supercam is also equipped with a microphone. This microphone (one of two on the rover) will allow scientists to hear the pop the laser makes upon hitting its target, which may give scientists additional information about the hardness of the rock.

Leaning more toward chemistry, the Planetary Instrument for X-Ray Lithochemistry (PIXL) will allow us to look at the composition of rocks and soil down to the size of a grain of salt. Elements respond to different types of light, such as X-rays, in predictable ways. So by shining an X-ray on Martian rocks and soil, we can identify elements that may be part of a biosignature.

Meanwhile, a device called SHERLOC will look for evidence of ancient life using a technique called Deep UV Raman spectroscopy. Raman spectroscopy can help scientists see the crystallinity and molecular structure of rocks and soil. For example, some molecules and crystals luminesce, or emit light, when exposed to ultraviolet – similar to how a blacklight might be used to illuminate evidence in a crime scene. Scientists have a good understanding of how chemicals considered key to life on Earth react to things like ultraviolet light. So, SHERLOC could help us identify those same chemicals on Mars. In other words, it can contribute to identifying those biosignatures we keep talking about.

Rounding out its role as a roving geologist on wheels, Perseverance also has instruments for studying beneath the surface of Mars. An instrument called the Radar Imager of Mars Subsurface Experiment (RIMFAX) will use ground-penetrating radar to analyze depths down to about 100 feet (30 meters) below the surface. Mounted on the rear of the rover, RIMFAX will help us understand geological features that can't be seen by the other cameras and instruments.

The rover's suite of instruments demonstrates how multiple scientific disciplines – chemistry, physics, biology, geology, and engineering – work in concert to further our understanding of Mars and help scientists uncover whether life ever existed on the Red Planet.

Next Generation Tech

At NASA, scientists and engineers are always looking to push the envelope and, while missions such as Perseverance are ambitious in themselves, they also provide an opportunity for NASA to test new technology that could be used for future missions. Two excellent examples of such technology joining Perseverance on Mars are MOXIE and the first ever Mars helicopter, Ingenuity.

MOXIE stands for the Mars Oxygen In-Situ Resource Utilization Experiment. Operating at 800 degrees Celsius, MOXIE takes in carbon dioxide (CO2) from the thin Martian atmosphere and splits those molecules into pure oxygen using what is called a catalyst. A catalyst is a chemical that allows for reactions to take place under conditions they normally wouldn’t. MOXIE provides an incredible opportunity for NASA to create something usable out of the limited resources available on Mars. Over the duration of the rover's mission, MOXIE will run for a total of one hour every time it operates, distributed over the course of the prime mission timeframe, to determine whether it can reliably produce breathable oxygen. The goal of operating this way is to allow scientists to determine the performance across a variety of environmental conditions that a dedicated, human-mission-sized oxygen plant would see during operations - day versus night, winter versus summer, etc. Oxygen is of great interest for future missions not just because of its necessity for future human life support on Mars, but also because it can be used as a rocket propellant, perhaps allowing for future small-scale sample return missions to Earth.

This artist's concept shows Ingenuity, the first Mars helicopter, on the Red Planet's surface with Perseverance (partially visible on the left) in the distance. Image credit: NASA/JPL-Caltech | › Full image and caption

The Mars Ingenuity helicopter is likewise an engineering first. It is a technology demonstration to test powered flight on Mars. Because the Martian atmosphere is so thin, flight is incredibly difficult. So, the four-pound (1.8-kilogram), solar powered helicopter is specially designed with two, four-foot (1.2-meter) long counter-rotating blades that spin at 2,400 rotations per minute. In the months after Perseverance lands, Ingenuity will drop from the belly of the rover. If all goes well, it will attempt test flights of increasing difficulty, covering incrementally greater heights and distances for about 30 days. In the future, engineers hope flying robots can allow for a greater view of the surrounding terrain for robotic and human missions alike.

In the News

A new spacecraft that will collect vital sea-surface measurements for better understanding climate change and improving weather predictions is joining the fleet of Earth science satellites monitoring our changing planet from space. A U.S.-European partnership, the Sentinel-6 Michael Freilich satellite continues a long tradition of collecting scientific data from Earth orbit. It’s named in honor of NASA’s former Earth Science Division director and a leading advocate for ocean measurements from space.

Read on to find out how the mission will measure sea-surface height for the next 10 years and provide atmospheric data to help better predict weather. Plus, find out how to watch the launch online and explore related teaching resources to bring NASA Earth science into the classroom and incorporate sea level data into your instruction.

How It Works

The Sentinel-6 Michael Freilich satellite is designed to measure sea-surface height and improve weather predictions. Once in orbit, it will be able to measure sea-surface height – with accuracy down to the centimeter – over 90% of the world’s oceans every 10 days. It will do this using a suite of onboard science tools, or instruments.

To measure sea-surface height, a radar altimeter will send a pulse of microwave energy to the ocean’s surface and record how long it takes for the energy to return. The time it takes for the signal to return varies depending on the height of the ocean – a higher ocean surface results in a shorter return time, while a lower ocean surface results in a longer return time. A microwave radiometer will measure delays that take place as the signal travels through the atmosphere to correct for this effect and provide an even more precise measurement of sea-surface height.

This animation shows the radar pulse from the Sentinel-6 Michael Freilich satellite's altimeter bouncing off the sea surface in order to measure the height of the ocean. Image credit: NASA/JPL-Caltech | + Expand image

To measure atmospheric data, Sentinel-6 Michael Freilich is equipped with the Global Navigation Satellite System - Radio Occultation, or GNSS-RO, instrument, which will measure signals from GPS satellites – the same ones you use to navigate on Earth. As these satellites move below or rise above the horizon from Sentinel-6 Michael Freilich's perspective, their signals slow down, change frequency and bend as a result of the phenomenon known as refraction. Scientists can use these changes in the GPS signal to measure small shifts in temperature, moisture content, and density in the atmosphere. These measurements can help meteorologists improve weather forecasts.

Why It's Important

Scientists from around the world have been collecting sea level measurements for more than a century. The data – gathered from tide gauges, sediment cores, and space satellites – paint a clear picture: sea level is rising. Looking at the average height of the sea across the planet, we see that in the last 25 years global sea level has been rising an average of 0.13 inches (3.3 mm) per year. This average is increasing each year (in the 2000s, it was 0.12 inches, or 3.0 mm, per year) as is the rate at which it’s increasing. That means that sea level is rising, and it’s rising faster and faster. Since 1880, global sea level has risen more than eight inches (20 cm). By 2100, it is projected to rise another one to four feet (30 to 122 cm).

Measuring sea level from space provides scientists with global measurements of Earth’s oceans in a matter of days, including areas far from shore where measurements aren’t practical or possible. Starting in 1992 with the launch of the TOPEX/Poseidon mission, the record of sea level measurements from space has continued uninterrupted, providing an increasingly detailed picture of Earth’s rising seas. The Sentinel-6 Michael Freilich satellite – and its twin, which will launch in 2025 – will extend those measurements to 2030, allowing scientists to continue collecting vital information about Earth’s changing oceans and climate.

Unlike previous satellites that measured sea level, Sentinel-6 Michael Freilich has the capability to measure sea level variations more accurately near coastlines, giving scientists insight into changes that can have direct impacts on communities and livelihoods, such as commercial fishing and ship navigation.

With rising seas already impacting people and communities, it's important to understand not just how much seas are rising, but also where and how quickly they are rising. Data from instruments on Sentinel-6 Michael Freilich can be combined with data from other satellites to get a clearer picture of what's contributing to sea level rise and where. For example, by looking at the satellite's radar altimeter measurements along with gravity measurements from the GRACE-FO mission, scientists can better determine how melting ice and thermal expansion are contributing to sea level rise. And by tracking the movement of warm water (which stands taller than cold water), scientists can better predict the rapid expansion of hurricanes.

Watch the Launch

Scheduled to launch at 9:17 a.m. PST (12:17 p.m. EST) on November 21, Sentinel-6 Michael Freilich will launch atop a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California.

Watch a live broadcast of the launch from the Vandenberg Air Force Base on NASA TV and the agency’s website. Visit the Sentinel-6 Michael Freilich website to explore more news about the mission. Follow launch updates on NASA's Twitter, Facebook and Instagram accounts.

Why It's Important

Perseverance may look similar to Curiosity – the NASA rover that's been exploring Mars since 2012 – but the latest rover's new science instruments, upgraded cameras, improved onboard computers and new landing technologies make it uniquely capable of accomplishing the science goals planned for the mission.

Looking for signs of habitability

The first of the rover's four science goals deals with studying the habitability of Mars. The mission is designed to look for environments that could have supported life in the past.

Perseverance will land in Jezero Crater, a 28-mile-wide (45-kilometer-wide) crater that scientists believe was once filled with water. Data from orbiters at the Red Planet suggest that water once flowed into the crater, carrying clay minerals from the surrounding area, depositing them in the crater and forming a delta. We find similar conditions on Earth, where the right combination of water and minerals can support life. By comparing these to the conditions we find on Mars, we can better understand the Red Planet's ability to support life. The Perseverance rover is specially designed to study the habitability of Mars' Jezero Crater using a suite of scientific instruments, or tools, that can evaluate the environment and the processes that influence it.

Seeking signs of ancient life

The rover's second science goal is closely linked with its first: Perseverance will seek out evidence that microbial life once existed on Mars in the past. In doing so, the mission could make progress in understanding the origin, evolution and distribution of life in the universe – the scientific field known as astrobiology.

Exploring Mars Lessons

Get students engaged in the excitement of NASA's next mission to Mars with standards-aligned STEM lessons.

It's important to note that the rover won't be looking for present-day life. Instead, its instruments are designed to look for clues left behind by ancient life. We call those clues biosignatures. A biosignature might be a pattern, object or substance that was created by life in the past and can be identified by certain properties, such as chemical composition, mineralogy or structure.

To better understand if a possible biosignature is really a clue left behind by ancient life, we need to look for biosignatures and study the habitability of the environment. Discovering that an environment is habitable does not automatically mean life existed there and some geologic processes can leave behind biosignature-like signs in non-habitable environments.

Collecting samples

Perseverance's third science goal is to gather samples of Martian rocks and soil. The rover will leave the samples on Mars, where future missions could collect them and bring them back to Earth for further study.

Scientists can learn a lot about Mars with a rover like Perseverance that can take in situ (Latin for "on-site") measurements. But examining samples from Mars in full-size laboratories on Earth can provide far more information about whether life ever existed on Mars than studying them on the Martian surface.

Perseverance will take the first step toward making a future sample return possible. The rover is equipped with special coring drill bits that will collect scientifically interesting samples similar in size to a piece of chalk. Each sample will be capped and sealed in individual collection tubes. The tubes will be stored aboard the rover until the mission team determines the best strategic locations on the planet's surface to leave them. The collection tubes will stay on the Martian surface until a potential future campaign collects them for return to Earth. NASA and the European Space Agency are solidifying concepts for the missions that will complete this campaign.

Preparing for future astronauts

Like the robotic spacecraft that landed on the Moon to prepare for the Apollo astronauts, the Perseverance rover's fourth science goal will help pave the way for humans to eventually visit Mars.

Before humans can set foot on the Red Planet, we need to know more about conditions there and demonstrate that technologies needed for returning to Earth, and survival, will work. That’s where MOXIE comes in. Short for Mars Oxygen In-Situ Resource Utilization Experiment, MOXIE is designed to separate oxygen from carbon dioxide (CO₂) in Mars' atmosphere. The atmosphere that surrounds the Red Planet is 96% CO₂. But there's very little oxygen – only 0.13%, compared with the 21% in Earth’s atmosphere.

Oxygen is a crucial ingredient in rocket fuel and is essential for human survival. MOXIE could show how similar systems sent to Mars ahead of astronauts could generate rocket fuel to bring astronauts back to Earth and even create oxygen for breathing.

Flying the first Mars helicopter

Joining the Perseverance rover on Mars is the first helicopter designed to fly on another planet. Dubbed Ingenuity, the Mars Helicopter is a technology demonstration that will be the first test of powered flight on another planet.

The lightweight helicopter rides to Mars attached to the belly of the rover. After Perseverance is on Mars, the helicopter will be released from the rover and will attempt up to five test flights in the thin atmosphere of Mars. After a successful first attempt at lifting off, hovering a few feet above the ground for 20 to 30 seconds and landing, the operations team can attempt incrementally higher and longer-distance flights. Ingenuity is designed to fly for up to 90 seconds, reach an altitude of 15 feet and travel a distance of nearly 980 feet. Sending commands to the helicopter and receiving information about the flights relayed through the rover, the helicopter team hopes to collect valuable test data about how the vehicle performs in Mars’ thin atmosphere. The results of the Mars Helicopter's test flights will help inform the development of future vehicles that could one day explore Mars from the air. Once Ingenuity has completed its technology demonstration, Perseverance will continue its mission on the surface of the Red Planet.

How It Works

Before any of that can happen, the Perseverance Mars rover needs to successfully lift off from Earth and begin its journey to the Red Planet. Here's how the launch is designed to ensure that the spacecraft and Mars are at the same place on landing day.

Watch Online

Explore virtual events and programming related to the launch of NASA's next Mars rover, including education workshops and conversations with mission experts.

About every 26 months, Mars and Earth are at points in their orbits around the Sun that allow us to launch spacecraft to Mars most efficiently. This span of time, called a launch period, lasts several weeks. For Perseverance, the launch period is targeted to begin at 4:50 a.m. PDT (7:50 a.m. EDT) on July 30 and end on Aug. 15. Each day, there is a launch window lasting about two hours. If all conditions are good, we have liftoff! If there's a little too much wind or other inclement weather, or perhaps engineers want to take a look at something on the rocket during the window, the countdown can be paused, and teams will try again the next day.

Regardless of when Perseverance launches during this period, the rover will land on Mars on Feb. 18, 2021, at around 12:30 PST. Engineers can maintain this fixed landing date because when the rover launches, it will go into what's called a parking orbit around Earth. Depending on when the launch happens, the rover will coast in the temporary parking orbit for 24 to 36 minutes. Then, the upper stage of the rocket will ignite for about seven minutes, giving the spacecraft the velocity it needs to reach Mars.

Like the Curiosity rover, Perseverance will launch from Launch Complex 41 at Cape Canaveral Air Force Station in Florida on an Atlas V 541 rocket – one of the most powerful rockets available for interplanetary spacecraft.

Besides providing an excuse to eat all varieties of pie, Pi Day gives us a chance to appreciate some of the ways NASA uses pi to explore the solar system and beyond. You can do the math for yourself – or get students doing it – by taking part in the NASA Pi Day Challenge. Find out below how to test your pi skills with real-world problems faced by NASA space explorers, plus get lessons and resources for educators.

How It Works

The ratio of any circle's circumference to its diameter is equal to pi, which is often rounded to 3.14. But pi is what is known as an irrational number, so its decimal representation never ends, and it never repeats. Though it has been calculated to trillions of digits, we use far fewer at NASA.

Pi is useful for all sorts of things, like calculating the circumference and area of circular objects and the volume of cylinders. That's helpful information for everyone from farmers irrigating crops to tire manufacturers to soup-makers filling their cans. At NASA, we use pi to calculate the densities of planets, point space telescopes at distant stars and galaxies, steer rovers on the Red Planet, put spacecraft into orbit and so much more! With so many practical applications, it's no wonder so many people love pi!

In the U.S., 3.14 is also how we refer to March 14, which is why we celebrate the mathematical marvel that is pi on that date each year. In 2009, the U.S. House of Representatives passed a resolution officially designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.

The NASA Pi Day Challenge

This year's NASA Pi Day Challenge poses four puzzlers that require pi to compare the sizes of Mars landing areas, calculate the length of a year for one of the most distant objects in the solar system, measure the depth of the ocean from an airplane, and determine the diameter of a distant debris disk. Learn more about the science and engineering behind the problems below or click the link to jump right into the challenge.

Mars Maneuver

Long before a Mars rover touches down on the Red Planet, scientists and engineers must determine where to land. Rather than choosing a specific landing spot, NASA selects an area known as a landing ellipse. A Mars rover could land anywhere within this ellipse. Choosing where the landing ellipse is located requires compromising between getting as close as possible to interesting science targets and avoiding hazards like steep slopes and large boulders, which could quickly bring a mission to its end. In the Mars Maneuver problem, students use pi to see how new technologies have reduced the size of landing ellipses from one Mars rover mission to the next.

Cold Case

In January 2019, NASA's New Horizons spacecraft sped past Arrokoth, a frigid, primitive object that orbits within the Kuiper Belt, a doughnut-shaped ring of icy bodies beyond the orbit of Neptune. Arrokoth is the most distant Kuiper Belt object to be visited by a spacecraft and only the second object in the region to have been explored up close. To get New Horizons to Arrokoth, mission navigators needed to know the orbital properties of the object, such as its speed, distance from the Sun, and the tilt and shape of its orbit. This information is also important for scientists studying the object. In the Cold Case problem, students can use pi to determine how long it takes the distant object to make one trip around the Sun.

Coral Calculus

Coral reefs provide food and shelter to many ocean species and protect coastal communities against extreme weather events. Ocean warming, invasive species, pollutants, and acidification caused by climate change can harm the tiny living coral organisms responsible for building coral reefs. To better understand the health of Earth's coral reefs, NASA's COral Reef Airborne Laboratory, or CORAL, mission maps them from the air using spectroscopy, studying how light interacts with the reefs. To make accurate maps, CORAL must be able to differentiate among coral, algae and sand on the ocean floor from an airplane. And to do that, it needs to calculate the depth of the ocean at every point it maps by measuring how much sunlight passes through the ocean and is reflected upward from the ocean floor. In Coral Calculus, students use pi to measure the water depth of an area mapped by the CORAL mission and help scientists better understand the status of Earth's coral reefs.

Planet Pinpointer

Our galaxy contains billions of stars, many of which are likely home to exoplanets – planets outside our solar system. So how do scientists decide where to look for these worlds? Using data gathered by NASA's Spitzer Space Telescope, researchers found that they're more likely to find giant exoplanets around young stars surrounded by debris disks, which are made up of material similar to what's found in the asteroid belt and Kuiper Belt in our solar system. Sure enough, after discovering a debris disk around the star Beta Pictoris, researchers later confirmed that it is home to at least two giant exoplanets. Learning more about Beta Pictoris' debris disk could give scientists insight into the formation of these giant worlds. In Planet Pinpointer, put yourself in the role of a NASA scientist to learn more about Beta Pictoris' debris disk, using pi to calculate the distance across it.

  ABOUT THE AUTHOR

  Lyle Tavernier is an educational technology specialist at NASA's Jet Propulsion Laboratory. When he’s not busy working in the areas of distance learning and instructional technology, you might find him running with his dog, cooking or planning his next trip.

The length of a year is based on how long it takes a planet to revolve around the Sun. Earth takes about 365.2422 days to make one revolution around the Sun. That's about six hours longer than the 365 days that we typically include in a calendar year. As a result, every four years we have about 24 extra hours that we add to the calendar at the end of February in the form of leap day. Without leap day, the dates of annual events, such as equinoxes and solstices, would slowly shift to later in the year, changing the dates of each season. After only a century without leap day, summer wouldn’t start until mid-July!

But the peculiar adjustments don't end there. If Earth revolved around the Sun in exactly 365 days and six hours, this system of adding a leap day every four years would need no exceptions. However, Earth takes a little less time than that to orbit the Sun. Rounding up and inserting a 24-hour leap day every four years adds about 45 extra minutes to every four-year leap cycle. That adds up to about three days every 400 years. To correct for that, years that are divisible by 100 don't have leap days unless they’re also divisible by 400. If you do the math, you'll see that the year 2000 was a leap year, but 2100, 2200 and 2300 will not be.

After learning more about leap years with this article from NASA's Space Place, students can do the math for themselves with this leap day problem set. Follow that up with writing a letter or poem to be opened on the next leap day. And since we've got an extra 24 hours this year, don't forget to take a little time to relax!

  Lyle Tavernier, Educational Technology Specialist, NASA/JPL Edu

  Lyle Tavernier is an educational technology specialist at NASA's Jet Propulsion Laboratory. When he’s not busy working in the areas of distance learning and instructional technology, you might find him running with his dog, cooking or planning his next trip.

Tell us about your background. How long have you been teaching?

Hagensmith: I've been teaching for 32 years total, with 29 of them at Toluca Lake Elementary. I began my teaching career in a split fourth- and fifth-grade classroom and moved to sixth grade for several years. But I have spent most of my career working with fifth graders.

Lee: This is my seventh year teaching and my fourth year teaching fifth grade. I have also taught kindergarten and second grade. Although there are aspects of teaching primary grades that I miss, fifth grade is my favorite of the three because the standards students are working toward are so comprehensive. It keeps me interested and excited about learning along with my students.

Wyatt: I have taught for almost three years. Before that, I was a teacher's assistant and instructional aid for three years.

How do you use resources from NASA in the classroom?

Hagensmith: I have used NASA resources to create hands-on lessons measuring the relative size of our solar system, to prepare a salad demonstrating the Sun's mass, to make bracelets with colored beads matching the chemical composition of the cosmos and assemble handmade telescopes.

Lee: Dennis and I recently attended an oceanography workshop put on by JPL that involved learning from teachers and researchers who had just completed cruises aboard the Exploration Vessel Nautilus. We were inspired to include similar activities leading up to and during an already-planned after-school screening of [the Netflix documentary] "Chasing Coral." The lesson complements other JPL lessons related to sea-level rise and global climate change.

Wyatt: Many of the JPL resources aren't just about science – they are generally thought-provoking activities. I use many of the activities pertaining to art because my students this year are artistically talented and curious.

How do you address the specific needs of your students and get the community involved in their education?

Hagensmith: Teaching in a low-income area, it is imperative that we find ways to make our families feel welcome and encourage academic excellence. Our goal is to create a school culture in which all realize their potential and make the most of their education. To that goal, we host a variety of parent and community nights each year, including Night of the Arts, Family Science Night, Family Reading Night, family writing workshops and Family Pi Night. The most popular of all of these is our annual Family Astronomy Night and Star Party. The evening always kicks off with a presentation from a visiting scientist, then families participate in a number of hands-on workshops. The most popular activity is often the telescopes provided by the Burbank Sidewalk Astronomers taking aim at various celestial objects.

This idea for the family events came about back in 2010 when I took a class at JPL with scientist Bonnie Burrati. The class inspired me to take steps to enhance my science instruction. We became a NASA partner school and began utilizing lessons from the NASA-JPL Education website. As a result of these lessons, two of our students – Ali Freas and Caitline Molina – were awarded a trip to NASA's Johnson Space Center in 2012 to participate in the Student Science Symposium. That year, we also presented NASA's "Space School Musical" at our annual Night of the Arts. I began doing the star party sometime around that era. Originally, it was just parents from my class and one guest presenter. As the years went by, we were able to recruit more teachers to host workshops and get speakers from JPL and UCLA. Last year, we had nearly 200 guests at the star party.

STEM Lessons

Bring the wonder of space to your students with standards-aligned lessons and resources from NASA-JPL Education.

Lee: I really try to maximize the impact of field trips. Students bring study guides and circulate through the tour, working as investigators searching for information and formulating their own conclusions about the topic we're exploring. This approach is useful for focusing student attention on key concepts at a wide range of locations. Recently, we visited the ecosystems and Space Shuttle Endeavour exhibits at the California Science Center, we've seen art at the Getty and Los Angeles County Museum of Art, and we've built cultural understanding at Los Angeles Plaza and the California African American Museum.

Wyatt: Many students that come to me struggle with social-emotional skills and really need a jump-start on how to express themselves without feeling overwhelmed or picked on by other students. It is very important to me to begin by engaging with my students in a way that communicates that they can feel safe, comforted and empowered when they are in my class. All students have the ability to express themselves and still be strong scholars. I strive to help my students find that sweet spot in my classroom.

One thing teachers struggle with, especially in primary grades, is making science cross-curricular. How have you brought science into the everyday lesson?

Hagensmith: Part of my success as a teacher has come from letting students direct their own assessments. I believe students need to see that learning isn't done in isolation. Subjects are connected with one another and with real-world applications. Each activity is preceded by lessons providing a context for students' learning. For example, after reading a book, students may create a diorama, write a review for the school newspaper, dress as one of the characters and get interviewed by peers, make a presentation and so forth. This provides a vehicle for students to build upon their unique skills and interests.

Lee: I've found success especially with topics related to the environment. I completed the National Geographic Educator Certification program last year, and that experience made a huge impact on me personally and professionally. I highly recommend it to all educators. National Geographic resources, combined with those offered by NASA-JPL, are guaranteed to create highly engaging, cooperative learning opportunities for students across all disciplines.

How It Worked

Human eyes can see only the portion of the electromagnetic spectrum known as visible light. This is because the human retina can detect only certain wavelengths of light through special photoreceptors called rods and cones. Everything we see with our eyes either emits or reflects visible light. But visible light is just a small portion of the electromagnetic spectrum. To "see" things that emit or reflect other wavelengths of light, we must rely on technology designed to sense those portions of the electromagnetic spectrum. Using this specialized technology allows us to peer into space and observe objects and processes we wouldn’t otherwise be able to see.

Infrared is one of the wavelengths of light that cannot be seen by human eyes. (It can sometimes be felt by our skin as heat if we are close enough to a strong source.) All objects that have temperature emit many wavelengths of light. The warmer they are, the more light they emit. Most things in the universe are warm enough to emit infrared radiation, and that light can be seen by an infrared-detecting telescope. Because Earth’s atmosphere absorbs most infrared radiation, infrared observations of space are best conducted from outside the planet's atmosphere.

So, to get a look at space objects that were otherwise hidden from view, NASA launched the Spitzer Space Telescope in 2003. Cooled by liquid helium and capable of viewing the sky in infrared, Spitzer launched into an Earth-trailing orbit around the Sun, where it became part of the agency's Great Observatory program along with the visible-light and near-infrared-detecting Hubble Space Telescope, Compton Gamma-Ray Observatory and Chandra X-ray Observatory. (Keeping the telescope cold reduces the chances of heat, or infrared light, from the spacecraft interfering with its astronomical observations.)

Over its lifetime, Spitzer has been used to detect light from objects and regions in space where the human eye and optical, or visible-light-sensing, telescopes may see nothing.

Why It's Important

NASA's Spitzer Space Telescope has returned volumes of data, yielding numerous scientific discoveries.

Vast, dense clouds of dust and gas block our view of many regions of the universe. Infrared light can penetrate these clouds, enabling Spitzer to peer into otherwise hidden regions of star formation, newly forming planetary systems and the centers of galaxies.

The bow shock, or shock wave, in front of the giant star Zeta Ophiuchi shown in this image from Spitzer is visible only in infrared light. The bow shock is created by winds that flow from the star, making ripples in the surrounding dust. Image credit: NASA/JPL-Caltech | › Full image and caption

Infrared astronomy also reveals information about cooler objects in space, such as smaller stars too dim to be detected by their visible light, planets beyond our solar system (called exoplanets) and giant molecular clouds where new stars are born. Additionally, many molecules in space, including organic molecules thought to be key to life's formation, have unique spectral signatures in the infrared. Spitzer has been able to detect those molecules when other instruments have not.

Both NASA's Spitzer and Hubble space telescopes contributed to this vibrant image of the Orion nebula.

Stars are born from condensing clouds of dust and gas. These newly formed stars are optically visible only once they have blown away the cocoon of dust and gas in which they were born. But Spitzer has been able to see infant stars as they form within their gas and dust clouds, helping us learn more about the life cycles of stars and the formation of solar systems.

Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from Spitzer. The colors in this image reflect the relative temperatures and evolutionary states of the various stars. The youngest stars are shown as red while more evolved stars are shown as blue.

Infrared emissions from most galaxies come primarily from stars as well as interstellar gas and dust. With Spitzer, astronomers have been able to see which galaxies are furiously forming stars, locate the regions within them where stars are born and pinpoint the cause of the stellar baby boom. Spitzer has given astronomers valuable insights into the structure of our own Milky Way galaxy by revealing where all the new stars are forming.

This Spitzer image, which covers a horizontal span of 890 light-years, shows hundreds of thousands of stars crowded into the swirling core of our spiral Milky Way galaxy. In visible-light pictures, this region cannot be seen at all because dust lying between Earth and the galactic center blocks our view. Image credit: NASA/JPL-Caltech | › Full image and caption

Spitzer marked a new age in the study of planets outside our solar system by being the first telescope to directly detect light emitted by these so-called exoplanets. This has made it possible for us to directly study and compare these exoplanets. Using Spitzer, astronomers have been able to measure temperatures, winds and the atmospheric composition of exoplanets – and to better understand their potential habitability. The discoveries have even inspired artists at NASA to envision what it might be like to visit these planets.

Thanks to Spitzer, scientists are learning more and more about planets beyond our solar system. These discoveries have even inspired a series of posters created by artists at NASA, who imagined what future explorers might encounter on these faraway worlds.

Data collected by Spitzer will continue to be analyzed for decades to come and is sure to yield even more scientific findings. It's certainly not the end of NASA's quest to get an infrared window into our stellar surroundings. In the coming years, the agency plans to launch its James Webb Space Telescope, with a mirror more than seven times the diameter of Spitzer's, to see the universe in even more detail. And NASA's Wide Field Infrared Survey Telescope, or WFIRST, will continue infrared observations in space with improved technology. Stay tuned for even more exciting infrared imagery, discoveries and learning!
