In this illustrated math problem, students use pi to calculate the approximate density of the asteroid (16) Psyche and compare that to the density of known terrestrial materials.

In this illustrated math problem, students use pi to figure out how much of the Sun’s disk will be covered by the Moon during an eclipse and whether it’s a total or annular eclipse.

In this illustrated math problem, students use the mathematical constant pi to find the "habitable zone" around a distant star and determine which of its planets are in that zone.

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

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

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

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

Using real data from NASA’s GRACE satellites, students will track water mass changes in the U.S.

Students draw and interpret topographic maps while learning about technology used to map Earth's surface, the seafloor, and other worlds.
