In this activity, learners verify that the Sun appears in a different location at a specific time every day of the year with one exception: on the Equinoxes.

In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

This fun and simple hands-on astronomy activity lets learners create 3D models of the Earth, Moon and Sun to demonstrate solar and lunar eclipses.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

This demonstration activity models how Venus appears from Earth.

In this activity, learners investigate passive solar building design with a focus solely on heating.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this board game, learners explore the origins of meteors, meteoroids, and meteorites as well as the their characteristics and importance. They also discover some misconceptions about meteors.

In this activity, learners make flipbooks of drawings showing the progression of a Total Solar Eclipse.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

This is an activity to do when there is a solar eclipse!

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

This is a classic exercise for visualizing the scale of the Solar System.

This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.
