Students explore different types of space missions and observation techniques that scientists use to study distant objects like asteroids.

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 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 the mathematical constant pi to find the "habitable zone" around a distant star and determine which of its planets are in that zone.

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

Students model the position of the planets around the Sun and then model viewing them from Earth on any given date.

Students will learn about the expanding universe and the redshift of lightwaves, then perform their own calculations with a distant supernova.
