In this illustrated problem set, students use pi to calculate the size of a Mars rock sample, compare the mirrors of two space telescopes, deduce an asteroid's makeup, and size up a solar eclipse.

In this illustrated math problem, students use pi to determine the volume of a rock core collected by the Perseverance Mars rover.

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.

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

Students use global temperature data to create models and compare short-term trends to long-term trends.

Students play a strategy card game that requires them to use problem-solving to successfully explore the Moon and Mars. Plus, *NEW* Outer Worlds Expansion Pack now available!

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

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 2023 now available for download!

Students use a planar model of a gravity well to create different orbital configurations around a central mass.
