On Monday, two cans with the same amount of water were placed outside, one in the sun and one under a tree. On Tuesday, some water had evaporated from the cans. Evaporated water molecules move farther apart and faster as water changes from a liquid to a gas. There was more water left in the can under the tree because it was shaded and prevented some evaporation.

THURSDAY I want to know how much water evaporated between Day 1 and Day 3.
1. In order to do this I need to measure the:
a. mass of the water in each glass
b. the temperature of the water
c. the volume of the water in each glass
d. the weight of the water in each glass
Day 1 Day 3 3. The units I would use to measure the
amount of water that evaporated would be
2. The tool that I would use would be
a. mL
a. balance scale b. L
b. graduated cylinder c. g
c. a spring scale d. ounces
d. a metric ruler
4. I would calculate how much water evaporated from Day 1 to Day 3 by
