Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

In this activity, learners work in NASA teams to build balloon-powered rockets using identical parts and compete to launch the greatest number of paper clips to "space" (the ceiling).

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

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