Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

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 measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.

In this activity, learners use their hands as tools for indirect measurement.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.
