Model of a Telephone

Telephones are a major communication tool.

The students engaged in an activity to fashion telephones using two plastic or paper cups with a long string. They used a tip of a pencil to pierce a hole at the bottom of each cup.

Then they threaded a long string through each hole and tied a big knot at each end. They held one cup over one ear and asked their partner to walk away holding the other cup.

The partner spoke into the cup and could hear the other partner speak even at a distance.
