Students learn about the role of dark energy and dark matter in the expansion of the universe, then make a model using balloons.

In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.

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

In this engineering challenge, students must stay within design limitations while creating a balloon and gondola system that can descend or ascend at a given rate or maintain its altitude.

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.
