A few months ago Luke came up with an experiment he wanted to do. He created a chart, wrote up what he was going to do, and kept track of his findings. Below I've typed up what he wrote since it's hard to read in this picture.
Question: Does water evaporate faster when the waters skin is greater?
Hypothesis: Water evaporates faster when the waters skin is greater.
Experiment: Take a cup and a bowl and put the same amount of water in each container. Whatever evaporates more in 6 days would have evaporated faster.
Cup: 1 1/2 inches around at waters surface (he used a measuring tape around the perimeter)
Bowl: 14 inches at waters surface
Analysis: The cup had 3/4 cups of water left and the bowl had 1/2 cup of water left.
Conclusion: Water with more surface area evaporates faster than with less.
Can you see his drawings at the bottom? He drew H2O molecules and wrote, enlarged to show detail.
I love it!

You have a little rocket scientist on your hands. Awesome!
He is brillant! What kid does this for fun? Just one that is going to be something really awesome someday!
