This week we started working with our “Water Cycle, Plants, and Light” unit. This week we learned all about the water cycle. In order to understand the water and why it rains, kids need to know about the water cycle first. I explained to them that water covers more than 70% of the earth’s surface, and living things need water to survive. The water cycle is nature’s way of purifying, circulating, and replenishing water.
We learned the four basic steps in the water cycle:
1. Evaporation: When heat from the sun turns liquid water into gaseous water vapor, causing it to rise into the air.
2. Condensation: When gaseous water vapor cools at high elevations and becomes liquid (or solid) again
3. Precipitation: When liquid water (rain) or solid water (snow) falls to the ground.
4. Collection: When large amounts of water gather in oceans, lakes, rivers, and streams
We did a simple demonstration to help the kiddos understand the basic elements of the water cycle, . We used water and ice. In a larger container I put hot water, stirred it well to make the ocean(evaporation). I covered the top of the container with a plastic wrap so we could see the water condense into clouds. We put some ice cubes into the center of the cling wrap covering the top of the container, so the cool ice in the “sky” would cause the evaporated water to condense when it rose up. After several minutes the kiddos could see water condensing into “clouds”, and then precipitation began with water dropping from the plastic, back into the ocean.
