48) Funnel Phone
Materials: 2 plastic funnels
4’ to 8’ of plastic tubing 3/8”
thick (available at hardware stores), tape
Directions: Fit each end of the plastic tubing in one of the funnels and tape in place. Have one child hold a funnel to his ear while another child talks into the other funnel. How does sound get from one funnel to the next?
Adaptations: Make individual phones with paper cups, string, and paper clips. Poke holes in the bottom of two cups and thread the string through the holes. Tie a paper clip to the ends of the string. Let children take turns speaking and listening with the “cup phones.”
