This KS2 / Elementary outdoor science investigation teaches students how evaporation causes cooling. Using two thermometers—one wrapped in a wet cloth and one in a dry cloth—students measure temperature changes outdoors every minute for 10 minutes and compare the results.
Learning Objectives:
Understand that evaporation causes cooling.
Record temperature data at regular intervals.
Compare results from two different starting conditions.
Work scientifically by observing, predicting, and measuring.
Discuss why the wet thermometer cools more quickly.
