WATER CYCLE
ObjectiveExplain and trace the possible paths of water through the
hydrosphere, geosphere, and atmosphere (the water cycle: evaporation, condensation, precipitation, surface run-off/groundwater flow) Provide examples of how the availability of fresh water for humans and other living organisms is dependent upon the water cycle. Relate the comparativeamounts of frest water and salt water on the Earth to the avaliability of water as a resource for living organisms and human activity. Describe the affect of human activities (landfills, use of fertilizers and herbicides, farming, septic systems) on the quality of water. |
ActivitiesUnderstand the percentage of water on earth and the forms in which the water exist. Use the USGS website to discuss these percentages.
Assessment: Two questions addressing the percentage of freshwater and the percentage of atmospheric water. Begin water cycle discussion using animation and video and interactive diagram. Now, use the USGS website to investigate the way water interacts as it changes within the water cycle. Complete the water cycle diagram. Discuss the diagram on the and then have students create a water cycle diagram in notebook. Give them the Notebook slide for the necessary information, and the Water Cycle Notebook Page requirements to complete assignment. Assessment: Scoring Guide for student created Notebook diagram. Use the website Scientific Facts about Water Resources to better understand the pressures we face on our water resources. Discuss the pressures on water resources, the forms and availability of water, human actions affecting our water, and how can we meet the demands on our water supplies in the future. Using the information from this comprehensise website, students will develop a Water Resources Action Plan to address topics for a Movie Maker activity. This action plan will organize the information into six steps; an introduction of the context of the video, pressures on water resources, where and in what forms is water available on Earth, how can human actions seriously affect water resources, how can the growing demand for water be met and a conclusion to bring these ideas together. Assessment: Action Plan Evaluation Once the action plan has been evaluated, the creation of the video can be completed. Using the Water Resources Movie Maker Activity to help with the structure, students will create a video approximately one minute in length addressing the information in the action plan.
