The Education Office at NASA’s Jet Propulsion Laboratory is always working to bring exciting scientific content to K-12 classrooms. Educators can access many of these free resources, classroom materials and activities online – and we’re adding more all the time. The inspiration for these products often comes from the work being done at JPL and NASA, but sometimes it’s the teachers we work with whose creative ideas inspire the lessons we share with our community of STEM educators. This blog is an effort to capture those creative ideas and highlight the teachers behind them.


Teacher Lina Khosrovian in her classroom

Ms. Khosrovian teaches third grade at Stonehurst Magnet Elementary in Los Angeles County.

Lina Khosrovian is a first-year teacher at Stonehurst Magnet Elementary, a STEAM magnet school in Los Angeles County. She teaches third-grade students subjects including language arts, math, science and social studies. Ms. Khosrovian recently reached out about how she added her own creative spin to the JPL lesson Art and the Cosmic Connection to have it reflect her multidisciplinary classroom.

What inspires you to teach?

I am in my first year of teaching, and I could not be more driven and excited to teach my students about all the wonders of life. I am a learner myself, and I strive to discover new and moving ways to instill knowledge upon my students.

I consider myself extremely lucky to be teaching at Stonehurst, where we have a passion for teaching STEAM to our students. I especially appreciate the students’ enthusiasm for learning science.

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

I have found that the key to effectively and successfully teaching students is to teach what they admire, are curious or fascinated about or have an appreciation for. I always ask my students about their interests and what they would like to learn. This inspires my lessons and tends to each students’ individual interest in learning.

How did you incorporate a JPL Education lesson into your classroom?

Art and the Cosmic Connection Lesson from NASA/JPL Edu

Art and the Cosmic Connection

In this lesson for grades K-12, students use art to describe and recognize the geology on planetary surfaces.

Brandon Rodriguez, an educator professional development specialist at NASA’s Jet Propulsion Laboratory, visited our school and presented a lesson called Art and the Cosmic Connection.

After showing us images of planets, Mr. Rodriguez handed out paper, chalk, crayons and markers, and instructed us to draw our own imaginary planet. Listening to his awe-inspiring lecture, I began to think about the beautiful garden at our school and wondered how I could incorporate it into a similar activity with my students. I decided that I would have my students create their own planet inspired by the school garden.

First, my students and I began to learn about different planets together, discussing the possible history of each unique world. We conversed and wrote about our theories. Then each student drew and wrote about their own, imaginary planet. Some students drew icy planets and said that the ice had melted when the planet was close to the Sun. Other students explained that the uniqueness of their planet was due to the presence of life and water.

With our knowledge, ideas and imagination, we grabbed paper bags to collect soil, sticks, hay, leaves, rocks and other natural items from the garden. Back in the classroom, each student began to construct 3-D versions of their drawings with the materials they collected. Their work was beautifully presented, with soil representing land, leaves representing life, blue paint representing water, and mixtures representing unknown and unique creations – plus some silver paint to make it all more “cosmic.”

How did it help you meet your objectives? How did students react to the lesson?

This lesson allowed my students to engage with the world around them and understand that planets have a uniqueness and a history that is quite remarkable. The lesson gave students a chance to discover more about their own planet and express their connection to it.

I sincerely value the JPL Education lessons, activities and resources, as they are quite beneficial to teachers. Each activity and lesson provides the opportunity for students to learn and wonder. And when you’re inspired to wonder, the possibilities are endless – and so is the fun!

Brightened processed image of Saturn from Cassini to highlight the F ring

Update – Feb. 24, 2017: The deadline for the Cassini Scientist for a Day Essay Contest has passed. The winners will be announced in May 2017.


In the News

Next week, NASA’s Cassini spacecraft will go where no spacecraft has gone before when it flies just past the edge of Saturn’s main rings. The maneuver is a first for the spacecraft, which has spent more than 12 years orbiting the ringed giant planet. And it’s part of a lead-up to a series of increasingly awesome feats that make up the mission’s “Grand Finale” ending with Cassini’s plunge into Saturn on Sept. 15, 2017.

How They’ll Do It

To prepare for the so-called “ring-grazing orbits,” which will bring the spacecraft within 56,000 miles (90,000 km) of Saturn, Cassini engineers have been slowly adjusting the spacecraft’s orbit since January. They do this by flying Cassini near Saturn’s large moon Titan. The moon’s gravity pulls on the spacecraft, changing its direction and speed.

On November 29, Cassini will use a big gravitational pull from Titan to get into an orbit that is closer to perpendicular with respect to the rings of Saturn and its equator. This orbit will send the spacecraft slightly higher above and below Saturn’s north and south poles, and allow it to get as close as the outer edge of the main rings – a region as of yet unexplored by Cassini.

This graphic illustrates the Cassini spacecraft's trajectory, or flight path, during the final two phases of its mission. The view is toward Saturn as seen from Earth. The 20 ring-grazing orbits are shown in gray; the 22 grand finale orbits are shown in blue. The final partial orbit is colored orange.

Why It’s Important

Cassini’s ring-grazing orbits will allow scientists to see features in Saturn's rings, up close, that they’ve only been able to observe from afar. The spacecraft will get so close to the rings, in fact, that it will pass through the dusty edges of the F ring, Saturn’s narrow, outermost ring. At that distance, Cassini will be able to study the rings like never before.

Among the firsts will be a “taste test” of Saturn’s rings from the inside out, during which Cassini will sample the faint gases surrounding the rings as well as the particles that make up the F ring. Cassini will also capture some of the best high-resolution images of the rings, and our best views of the small moons Atlas, Pan, Daphnis and Pandora, which orbit near the rings' outer edges. Finally, the spacecraft will do reconnaissance work needed to safely carry out its next planned maneuver in April 2017, when Cassini is scheduled to fly through the 1,500-mile (2,350-kilometer) gap between Saturn and its rings.

These orbits are a great example of scientific research in action. Much of what scientists will be seeing in detail during these ring-grazing orbits are features that, despite Cassini’s 12 years at Saturn, have remained a mystery. These new perspectives could help answer questions scientists have long puzzled over, but they will also certainly lead to new questions to add to our ongoing exploration of the ringed giant.
