Slide 2 The Water Cycle start Slide 3 The Water Cycle The water cycle has no beginning and no end, but it does have several stages that the water will go though. Here are the steps to the water cycle: follow the arrows CLICK on each step to find out more! Precipitation MOVIE Slide 4 Evaporation: A change from liquid to vapor form. Water evaporates when heated Click to return NEXT Slide 5 Condensation: Change of substance from the vapor state to a denser liquid or solid state Clouds or dew forms when vapor is cooled Click to return NEXT Slide 6 Precipitation: water droplets rain, fog, mist, dew, snow or hail. When the clouds become too big and heavy with water droplets, the water starts falling to earth as either rain, fog, mist, dew, snow or hail. Click to return NEXT Slide 7 Watch This Video! NEXT Slide 8 What is the heat source that drives the water cycle? A B C D The clouds The Wind The Sun Electricity NEXT Slide 9 Try again! Click to return Slide 10 Correct! The water cycle is powered by the heat of the sun NEXT Slide 11 Water is Everywhere! Ground water Fresh surface water Snow Ocean Atmosphere NEXT Slide 12 GAME! Droplet and the Water Cycle And so begins the adventure of Droplet, the water molecule, as he enters the great water and starts his journey home. Your task, as you play this game, is to get him safely through the forest, into the river, and out to sea so that the sun can warm him once again and help him get back to the clouds. Good luck and have a safe trip! PLAY Next Slide 13 THE END! To Core Standards and References Slide 14 Fourth Grade Content Standard 1 Students will develop an understanding of their environment. Objective 2 Describe the water cycle. Locate examples of evaporation and condensation in the water cycle (e.g., water evaporates when heated and clouds or dew forms when vapor is cooled). Describe the processes of evaporation, condensation, and precipitation as they relate to the water cycle. Identify locations that hold water as it passes through the water cycle (e.g., oceans, atmosphere, fresh surface water, snow, ice, and ground water). Construct a model or diagram to show how water continuously moves through the water cycle over time.
