This demonstration uses a water balloon to show how Earth's oceans are absorbing most of the heat being trapped on our warming world.

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 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.

Students code microcontrollers to send and receive radio signals, simulating communications between Earth and spacecraft.
