Material Detail

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes. Participants imagine themselves inside a large star at the end of its life, just as it is about to go supernova. This activity simulates the momentum transfer from the denser material of the core (represented by the tennis balls) to the lighter material of the outer layers (represented by the ping-pong balls) after the star's core collapses. The pdf contains step-by-step instructions, photos, presentation tips, and links to background information.
