Across the Water

Materials

1. Jelly roll pans, or any flat metal or plastic lid with sides
2. Water
3. Styrofoam packing pieces
4. Food coloring

Instructions

1. Place each pan on a table.
2. Pour in a small amount of water to cover the bottom of the pans.
3. The children can make ripples in the water by blowing gently. Give a name to this wind (gentle breeze, light wind).
4. Two children can stand across the table from each other and blow pieces of Styrofoam back and forth. Investigate to find out what other objects can be moved by the wind on the water.
5. Observe the change in the water as you add drops of food coloring. Swirl the water around and watch as it gradually turns a different color.
6. Compare gentle wind to strong wind by letting two children stand on the same side of the table and blow. Give names to the strong wind (blustery, windy, gale, storm, etc.). After your storms, there will be cleaning up to do!
