Name: ______________________________________ WHY CONSERVE WATER? The issue of water conservation is not about “saving” water—it is about having enough clean water at any given time and place to meet our needs. Gifford Pinchot, an American conservationist and politician who served as chief of the U.S. Forest Service (see below) between 1898 and 1910, referred to conservation as “The wise use of the earth and its resources for the lasting good of men.” The conservation of our water resources depends on our wise use of these resources. Such wise use, without a doubt, begins at home and in our community. As we attempt to meet the water use needs of a growing population, issues of water quality and quantity will gain increasing significance in years to come. We cannot afford to take our water resources for granted—not even here in the water-rich Northeast. Droughts, for example, are natural occurrences that can cause water shortages. But human activities can cause water availability problems as well. In some instances, communities have had to seek other sources of drinking water because their water supply well had been contaminated. For example, infiltration of gasoline from a leaking underground storage tank into a ground water supply well is all it can take to reduce a fresh drinking water and make it unusable. Once ground water becomes contaminated, it can take years or decades for it to clean itself naturally (Established in 1905, the Forest Service is an agency of the U.S. Department of Agriculture. The Forest Service manages public lands in national forests and grasslands.) Your Conservation Challenge Over the next 5 days you will be challenged to conserve the battery in your classroom ipad. You will be asked to complete assignments during the week that may make using the ipad easier, but it will not be the only way you can get the information. You may have to seek “other” ways to help you complete the assignments. You will also be sharing the ipads with Ms. Difiore’s classes, as well as my other classes. You may not be able to control how much of the ipad battery they use but you may be able to find ways to inform them of on how to conserve the battery. The better you are about informing others about conserving, the better chance you will have at having the highest percentage of battery at the end of the week. Use the chart below to keep track of your battery use: Ipad #: ____________ Date Battery Charge before class Battery Charge after class Battery charge lost or gained Monday Tuesday Wednesday Thursday Friday Total battery charge on Friday: _______________ Monday’s homework: Below please brainstorm 3 different ways you can inform others to conserve the battery on your classroom ipad. 1. 2. 3. Earth’s Water: A Drop in your Cup CCCS: 5.4.8. G. 2, 5.4.6. G 3 Objective: 1. Students will learn that Earth has a limited amount of fresh water. 2. Students will learn ways to conserve freshwater and brainstorm ideas to increase usage of untapped water resources in their local area. Vocabulary: 1. resource: a natural, economic, or political asset that can be drawn upon when needed 2. desalination: a process that removes salt from seawater to produce drinkable water 3. fresh water: water that contains minimal amounts of salt (as opposed to saltwater in the oceans) 4. scarcity: the state of being in short supply Monday: How much water is on the planet? DO NOW: With your partner, brainstorm NATURAL resources of water. Resources of Water: 1. 2. 3. 4. 5. 6. 7. 8. Activity: How much water is freshwater? In class today, you watched me distribute the Earth’s freshwater into small cups. The water in these cups represents the percentage of that particular water resource on our planet. With your classmates, decide which cup of water goes with which resource of water we listed above. Use the globe and or ipad to make an educated guess. Bottle A: _____________________ ______________ Percentage on the planet: Cup B: _______________________ ______________ Percentage on the planet: Cup C: _______________________ ______________ Percentage on the planet: Cup D: _______________________ ______________ Percentage on the planet: Cup E: _______________________ ______________ Percentage on the planet: Cup F: _______________________ ______________ Percentage on the planet: Cup G: _______________________ ______________ Percentage on the planet: Cup H: _______________________ ______________ Percentage on the planet: Percentage of water on the planet: _____________ Percentage of salt water: _______________ Percentage of freshwater: ______________ Percentage of accessible surface fresh water: ______________ You may now drink the liquid if you want to, but first you must decide how to divide it amongst the other students in the class. Discuss with each other how you might share your portion of the water. Consider the following: 1. Freshwater has to accommodate the needs of plants and animals as well as humans. 2. The salt water cannot be used for drinking. Although, salt water can be put through a process called desalination, it is very expensive and uses a lot of energy. 3. Ice and glaciers are difficult to get to and is not readily available for human use. How does this activity relate to the scarcity of water? ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________ What do I mean when I say we must “conserve” water? (hint: it does not mean “save” water) ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________________________________________ ________________________________ Before you leave today: Because fresh, drinkable water is such a limited resource, it is important to conserve water in our daily lives. On a post-it give me one way you might try to conserve water?
