"A" Science Experiments and Activities

A
Absorb - Put a sponge in water. Observe the water absorb into the sponge.

Air
Blow a feather across the floor.
Put some water into a container and blow on it.
Blow on your hand.
Blow a balloon up. Play with it.

Air in a Bag
Materials:
Straw
Book
Zipper Sandwich Bag

Predict what will happen when you blow air into the bag. Take a straw and place it in the center of a plastic bag. Seal it on the sides towards the straw. Place it under the book. Blow into the straw. Observe what happened.

Air Pressure 
Experiment - Fill a sink (or container) of water (enough to cover the cup). Have the child(ren) predict if water will go in the cup or not. Push a clear plastic cup into the water. Take the cup out of the water. Did any water get into the cup? Was the cup heavy or light? After doing that several times, let the children experiment with the cup and let water enter into the cup. Was the cup with the water in it heavier or lighter than the cup with "just air" in it?

Astronomy - Look outside during the day or the night. What do you see?
