Students create a scale model of the solar system using beads and string.

Students predict the scale of our solar system and the distance between planets, then check their answers using fractions.

Students will use the engineering design process to design, build, test and improve a model satellite intended to investigate the surface of a planet.

Students explore practical applications of exponents and division to investigate what it takes for NASA spacecraft to travel deep into the solar system using only solar power.

In this video lesson, students learn to design, build and launch paper rockets, calculate how high they fly and improve their designs.

Students use the Danjon Scale of Lunar Eclipse Brightness to illustrate the range of colors and brightness the Moon can take on during a total lunar eclipse.

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic.

Whip up a moon-like crater with baking ingredients as a demonstration for students.

Students use satellite and rover images to learn about the various features and materials that cause color variation on the surface of Mars, then create their own “Marscape.”
