What is air?
What causes air to move?
Experiment: Air exists
Equiptment
- Container filled with water
- Jar
- Paper towel
Prediction
It think that the paper will stay dry because the air is trapped in the jar with no way to escape.
Observe
When you put the paper towel in the jar and then place the jar in the water upside down and then lift the jar out of the water and the paper towel will still be dry.
Explain
In our groups, we all run down to the water troth and fill our bucket with water then we all run back to the class. We scrunch up the paper towel and put it in the jar and then tip it upside down and place it in the bottom of the bucket then lift it back up. The paper towel stays dry. Why? Because the jar is filled with air and then when you put the paper towel in the jar it is surrounded by air so when you put the jar under the water facing down the air has no way to escape.
Wow, it actually worked!
