Draw a shape on cardboard. A grown-up cuts it out. Tape it to a craft stick or straw. Make one more puppet from wax paper. Shine a flashlight at a wall. Put on a show!
Safety first
A grown-up uses the scissors. Never shine the light into eyes.
For a grown-up
Ask: what did you notice? Ask: what would you change next time? Compare the cardboard shadow and the wax paper shadow.
