Students use global carbon dioxide (CO2) concentration data since to plot major life milestones of themselves, their parents, and grandparents along a curve.

Students observe the process and results of transpiration from a plant in their schoolyard.

Students design a robotic insect for an extraterrestrial environment, then compare the process to how NASA engineers design robots for extreme environments like Mars.

Using the fundamental criteria for life, students examine simulated extraterrestrial soil samples for signs of life.

In this standards-aligned unit, students learn about Mars, design a mission to explore the planet, build and test model spacecraft and components, and engage in scientific exploration.

These 60-second videos answer some of the most frequently asked questions about our planetary neighbor, Mars, and the spacecraft that explore it.

In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

This six-part video series walks educators and students through the ins and outs of crafting a science fair project.

Launch rockets, build a hovercraft, create a winning science fair project and more! These science, technology, engineering and math activities are fun for kids, adults and the whole family.
