First Grade Using Vibrations to Communicate

As a culminating project for our 1st grade lessons on sound and light, we started out having the kids use "cylinders" and "string" to communicate over a distance (about 6-8 feet). We put out a bunch of containers with holes and an collection of different types of connecting materials.

From there they got together in pairs and experimented with different combinations.

After a few minutes, we regrouped and reviewed what they knew about how sound moves. We came to the conclusion that the vibrations move best through a tight connection.

One group wanted to see if you could hear other people talking if you crossed lines...so they tried it.
