Students are trying to make sense of what happens to the water droplets they seemingly saw disappear on both the paper towels and the plastic cups. Many students suggested the water evaporated, but what does evaporation really mean? How can we gather evidence to support the claim that the water evaporated?
How long does it take to have water evaporate? Since many bodies of water contain much more than just "water," we've set up three two-bottle systems to see just what happens! One system contains sand/water, another contains salt/water, and the third contains blue food coloring/water. We made observations and predictions today for what will happen to the water over time as the light is turned on...
Wait and see!!!
