Water Cycle Stations

Watch it! Ted-Ed: How Do Clouds Affect Earth’s Temperature? Directions: Watch the video below and answer the question “How Do Clouds Affect Earth’s Temperature?” http://ed.ted.com/lessons/cloudy-climate- change-how-clouds-affect-earth-s-temperature- jasper-kirkby

Explore it! Directions: Working with a partner or group, discuss the following questions: What would the lamp represent and what type of heat transfer is this? What do you think the plastic wrap would represent? If this represented a true model of the Earth, what percentage would be land (the small cup filled with rocks) and what percentage would be water? Then explain how you know that each process below is or has occurred in “Water Cycle in a Beaker.” You should only observe the beaker, NOT TOUCH! Try to collaborate and talk with a partner or group about each process

Read it! Directions: Read “Walter the Water Molecule” (pg. #5 of PDF File) story in the ISN folder of your Class Notebook. Next to each paragraph, write the process(es) that is or are occurring. Highlight the evidence from the paragraph that supports the process occurring. Sign your sheet when finished. There should be highlighting and words next to EVERY paragraph.

Map it! Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation.  Directions: Fill out the flow map below showing the formation of dew. You can use words or words AND pictures. Your flow map should show what is happening to the molecules and WHY. The following words should be used: Condensation, Water Vapor, Liquid, Humidity, Molecules Website: http://www.todayifoundout.com/index.php/201 2/06/what-causes-dew/

Organize it! Directions: Match each process of the water cycle, to the picture, to the description, to the picture. Try to do it without using your notes, and then use your notes to check it. Finally, use the answer key in the folder to check it.

Assess it! Directions: Answer the 7 questions on your sheet. Check your answers using the answer key in the folder. If incorrect, read and analyze why the actual answer is correct.

Assess it! 4. 1. 3. 5. 2. 6.

Answer Key D Water to ice is freezing (through cooling). Ice to water is melting (through heating). Water to gas is evaporating (through heating). A Dew is created through condensation. On humid days, there is a lot of water vapor in the air. At night when the temperature cools, the water vapor turns to water droplets (dew) on the grass through condensation. 18 degrees is more than freezing so it would not be frost. C The water is seeping below the ground (Zone A), which is infiltration. Ground must be permeable for water to seep through. Condensation occurs when the water vapor (gas) molecules begin to cool. This causes the molecule to move slower and together, turning into a liquid. Melting and Evaporation involves heating. The sun’s radiation causes the water to evaporate, which is essential for the water cycle. Without evaporation, there would be no water vapor in the atmosphere and therefore no clouds or precipitation. Evaporation and transpiration change water to water vapor through heating. This allows the water to enter the atmosphere, or the air.
