Science Experiments - Mini Water Cycle
The purpose of this Science for Kids activity is for children to discover how water is cleaned using a mini water cycle.
Materials:
16 oz. clear plastic cup, 3 drops of food coloring, 8 oz. warm water, ice cube, 8" square of clear plastic wrap, rubber band, paper towel
1. Place the cup on the paper towel. Put the food coloring in the cup and add the warm water.
2. Stretch the plastic tightly over the cup and secure with a rubber band.
3. Place the ice cube on top of the plastic wrap. Ask the kids what they think will happen when warm vapor from the colored water hits the cooler plastic above it (it will condense/form drops). What color will the drops be? (clear) Why? (As water evaporates, the food coloring is left behind.)
The kids have just seen how water is cleaned through the water cycle!
