This video explains how NASA's Deep Space Network uses a system of giant antennas located around the world – and electromagnetic energy – to talk to spacecraft.

Students explore the science behind an intriguing planetary feature by creating saline solutions and then observing what happens when the solutions evaporate. Now updated with findings from Mars!

Students make predictions and observations about how ice will melt in different conditions then compare their predictions to results as they make connections to melting glaciers.

In this lesson, students use their knowledge of moon phases to build a calendar they can use to find out when and where to see each phase of the Moon throughout the year. Calendar for 2022 now available for download!

In this lesson, students build a paper helicopter, then improve the design and compare and measure performance.

Student teams use the engineering design process and everyday materials to design an insulator that will keep a small amount of water from rapidly changing temperature.

Students learn how Mars rovers use spectroscopy to study the chemical composition of rock samples on the Red Planet then model the process in the classroom.

Students will learn about the expanding universe and the redshift of lightwaves, then perform their own calculations with a distant supernova.

Students decide what they want to learn from a robotic mission to Mars and what tools they will put on their robot to accomplish their goals.
