Question

Zelda noticed a puddle outside her front door. She saw that the puddle got smaller every day, until the 3rd day when it was completely gone. The next week, she noticed the puddle again. This time the puddle was gone the next day. Since the sun was out the second week but not the first week, Zelda hypothesized that the heat from the sun was the reason for the water evaporating at a faster rate. If she were to set up two containers with equal amounts of water, what would be the best way for Zeldato test her hypothesis\

Answer 1

Answer: Zelda should place one container of water in sunlight (by a window or outdoors) and the other container in a dark room (closet) away from the sun.

Explanation: This would allow Zelda to test two different settings (sun and no sun) so she can test her hypothesis.
