Possible Hypotheses:

Materials:

Two large plastic containers Clear plastic wrap Masking tape Two small rocks Two small glasses Two tablespoons of dirt Two tablespoons of salt Water

Procedure:

1. Fill both plastic containers with one inch of water. Mix the dirt into the water in one and the salt into the other.

2. Place one empty glass upright into the middle of each plastic container. Make sure it remains empty.

3. Cover both plastic containers tightly with plastic wrap and seal them with tape. Place a small rock in the middle of the plastic wrap directly over the glass but not touching it.
