Design and craft a mobile that reinforces our understanding of the water cycle.
Earth has a limited supply of water that is cycled over and over again. The water cycle is an important process on earth because living things, including animals and humans, need water to grow and survive. Water is used for drinking, growing food, providing habitat, generating electricity and more. The sun has been driving the water cycle on Earth for billions of years. The four main stages of the water cycle are evaporation, condensation, precipitation and runoff.
This activity uses paper cut into strips. The strips for condensation and runoff should be longer and wider than the precipitation and evaporation strips.
Conservation tip: cut letter size paper into three vertical strips (approximately 7 cm wide) for condensation and runoff, two for each student. Cut paper into twelve horizontal strips (approximately 2 cm wide) for precipitation and evaporation. Each student needs six.
You can cut the strips for evaporation, precipitation, condensation and runoff ahead of time or have students do it. Feel free to use coloured paper, construction paper or have students decorate the strips themselves.
