Thermometers and Water Cycle

During fourth grade’s weather unit, I demonstrated how to make a “homemade” thermometer with a bottle, straw, clay, and water colored with food coloring. Click here for directions. In the photos below, the water moved in the straw as the temperature changed throughout the day. I also taped a water cycle bag on my window. Fourth graders made these during online instruction. As the water heats up, it changes to water vapor, condenses, and then falls again as precipitation down the side of the bag. Click here for additional directions. (Food coloring is optional.)
