In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

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 will compare predicted and observed tides using data from The National Oceanic and Atmospheric Administration(NOAA).

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