In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.

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 model the gravitational fields of planets on a flexible surface.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

Through a series of simple body movements, learners gain insight into the relationship between time and astronomical motions of Earth (rotation about its axis, and orbit around the Sun), and also abou

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners drop impactors onto layers of graham crackers!

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
