The Water Cycle by: Meghan Maloney & Trisha Anderson

1. The Water Cycleby: Meghan Maloney & Trisha Anderson Introduction Task Process Evaluation Conclusion Teachers page

2. Introduction Have you ever wondered where all the water you drink comes from? Is the water we have on Earth today the same water that was here millions of years ago? Could you possibly be drinking the same water a dinosaur drank centuries ago? Today we will investigate the water cycle and all the different parts. 

3. Task You will be working with a partner to complete the following tasks: • Brainstorm 12 different ways that we use water everyday. Use this worksheet to get you started-ways we use water. • Research the water cycle on the internet using the following website hydrological cycle and also look at this information to fill out this small quiz: water cycle quiz • Finally, construct a water cycle wheel using the worksheets moving raindrops and the water cycle wheel-your final product will look like this:

4. Process Read the following information to get an idea of how the water cycle works! Click here to see what evaporation is. Click here to see how condensation works. Click here to see what precipitation is. Click here to see what collection is. Also take a look at the water cycle animation for more information.

5. Evaporation • Evaporation is when the sun heats up the water from oceans, lakes, or rivers and turns it into vapor/steam. Then the steam leaves the surface and goes into the air.

6. Condensation • Condensation is when water vapor in the air gets cold and turns back into liquid, forming clouds.

7. Precipitation • Precipitation happens when so much water has formed in the clouds and they cannot hold anymore. The clouds get heavy and water falls back down to the earth through rain, sleet, snow, and hail.

8. Collection • Collection is when the water falls back to the earth and collects is various places. • when it ends up on land it can either soak into the land and become “ground water” or run back into the oceans, rivers and lakes and that is called “runoff” water. • And the cycle starts all over again!

9. Evaluation You and your partner will be graded on the quiz you completed as well as the following:

10. Conclusion • Great job on being investigators of the water cycle! • Now every time you take a drink of water think of where it came from. • For fun you can read about drippy the raindrop and his adventures!

11. Teacher’s Page A- Pennsylvania Academic Standards Subject : Science and Technology Area 3.5: Earth Sciences Grade 3.5.4:   Grade 4 Standard D.:  Recognize the Earth’s different water resources. • Know that approximately ¾th of the earth is covered by water. • Describe locations of fresh and salt water in or near the state of Pennsylvania. • Identify examples of water in the form of solid, liquid and gas on or near the surface of the earth. • Explain and illustrate evaporation and condensation. • Recognize other resources available from water (e. g., energy, transportation, minerals, food). • Objectives: have students recognize parts of the water cycle and understand where water comes from.
