Air Experiments

The fifth graders conducted 10 experiments about air. They were able to see air take up space because air bubbles came out of a brick and a bottle. A piece of paper stayed dry in a cup that was put straight down in a tub of water. Wow! There was air in the cup so the water couldn't go into the cup. The students witnessed air having pressure when they flipped over a cup of water with a piece of posterboard on it. It was like magic when the paper stayed on the cup, and the water didn't spill out. They proved air has a little weight when they balanced a balloon with air and one without air. It took a steady hand to try to hold a quarter with two straight pins and blow it like a windmill to show air does work. Also, air that they blew into balloons lifted books. Lastly, they proved that warm air rises when they saw the spiral paper move that was above the warm lamp. Also, the balloon over the bottle sitting in warm water had air go to the top of the balloon and actually blow up a little. I think the students had fun while learning about air.
