Lets Think About...Air

Activities:

1. Air Takes Up Space

Use 2 balloons of equal size and shape and color. Fill one with water and the other with air. Ask the children which one will be heavier and which one lighter? Have them test for results. Which is heavier? Air or Water? With older children, you may weigh and record the weights.

2. Air Can Be Strong and Move Things

Place a ping-pong ball in a basin of water. Ask the children if there is a way to make the ball move without touching it. Have one child at a time try blowing the ball to see if the child can make the ball move.

Blow up balloons and float them on water. How can you make them move without touching them?

Some suggestions:
Try blowing air on the balloons through a plastic straw or some plastic tubing. Use a paper plate and wave it like a fan at the balloon.

3. Many Things Need Air to Work

Balloons, Balls, Bubbles - all are filled with air.

Bubble Blowing:

Add 1/4 cup of Dawn dishwashing detergent to a basin of water. Use bubble blowing equipment of varying sizes to make bubbles. (Plastic strawberry boxes can be used to make small bubbles, while covering hangers with yarn can make large bubbles.)

4. Air Can Make Sounds

Blow up balloons and then slowly let out the air by narrowing the opening of the balloons. Listen to the sounds that can be heard.
