Our next experiment got us wondering about best locations for water to evaporate. We gather all the house thermometers, four trays, and four cups. The kids measured 35 ml in each cup.
They placed a cup, and a thermometer in each tray. They brainstormed about what places in the house will make water evaporate, and what places would make it stay in its liquid form.
Little Guy placed one tray in our hallway bathroom. It has very little light, and does not get much use. He also chose to leave another tray in the learning space by a sunny window.
Big Sister chose to place one of her trays inside the refrigerator, and the other one in between the refrigerator and the stove.
After a few days, here is what we found: The water in the learning room (exposed to the sun) completely evaporated. The water in the refrigerator didn't evaporate at all.
We compared the water left over to see what places evaporated more water or had less water left.
We also measured how much water was left.
We recorded the temperature of each location and compared them to see how it impacted the evaporation rates.
We compiled all our data on the white board, but I forgot to take a picture of it. Basically, we had a graph with the locations, amount of water left, temperature, and evaporation ranking from best, to worst place.
