In this activity, learners investigate and compare the rate of drying in different conditions. Learners place wet dish cloths in front of a fan, on a flat surface inside the room, in a box with a lid, and outside on the grass or in the sun by a window and record the dampness on a chart every ten minutes. Learners discover that wind can impact the speed of water evaporation. This activity can also be used to introduce learners to the scientific method.
