6. Evaporation Experiment
Step 1: fill a glass measuring cup with water
Step 2: wait one day and mark the new water level
Step 3: repeat step 2 over several days and compare the
new water level to the original level
You will see evaporation!
Water vapor in the air changes from a gas to a liquid
Cool temperatures cause this
The liquid collection forms clouds
8. Condensation Experiment
Step 1: fill a glass with ice
Step 2: let it sit on the counter for a few minutes
Step 3: observe the water droplets that appear on the
outside of the glass
How did they get there?
