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 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 build a paper helicopter, then improve the design and compare and measure performance.

In this activity, students learn how light and energy are spread throughout space. The rate of change can be expressed mathematically, demonstrating why spacecraft like NASA’s Juno need so many solar panels.

Students model different densities of Jupiter’s moon Europa to investigate what might lie beneath the icy surface.

Students use a spreadsheet model to understand droughts and the movement of water in the water cycle.

In this illustrated problem set, students use pi to collect samples from an asteroid, fly a helicopter on Mars for the first time, find efficient ways to talk with distant spacecraft, and study the forces behind Earth's beautiful auroras.

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.
