<Tab/>Water never stops moving. Snow and rain fall to the earth from clouds. The rain and melted snow run downhill into rivers and lakes, sometimes crashing over waterfalls. Eventually the water flows into the ocean. During evaporation, the water turns from liquid into gas, and moves from oceans and lakes into the atmosphere where it forms clouds. Then the cycle begins all over again.
<Tab/>The first experiment I did, built my own water cycle. You could use this experiment with elementary students. Materials needed are a jar, plants, bottle cap or shell of water…
