WATER RESOURCES Learning targets At the end of this lesson, you should be able to say, "I can"... 1. Describe how water is distributed on earth; 2. identify the various water resources on earth; 3. explain how different activities affect the quality and availability of water for human use; and 4. suggest ways of conserving and protecting water resources. Colors of Earth Colors of Earth There is more water on Earth than land because EARTH IS IN THE HABITABLE ZONE, where the temperature allows liquid water to exist. This, combined with Earth's stable atmosphere and water cycle, ensures that water covers most of the planet, creating an environment that supports life. 1. Why care about water? 2. How do you spend your water at home and at school? Water is an important natural resource however it is not equally distributed in our planet. Various Water Resources Various Water Resources 1. Oceans 2. Freshwater Various Water Resources 1. Oceans There are five recognized oceans. These are the Pacific, Atlantic, Indian, Arctic, and Southern Oceans THE FIVE OCEANS Various Water Resources 2. Freshwater Freshwater constitutes around 2.5% of water on the Earth's surface. How much water is available for human use? Fact: Most of the Earth’s Freshwater are found in ice caps and glaciers G r o u n d wa t e r i s wa t e r t h a t se e p s i n t o t h e g r o u n d a n d f i l l s u p t h e o p e n sp a c e s i n r o c k s, se d i ment s , and soi l beneat h t he Ea r t h ' s su r f a c e.

Roles Assignment for Role Playing: Specific role in each group, such as: 1. FARMER: Concerned with water for irrigation and agriculture. 2. CITY RESIDENT: Focused on water usage for households and daily living. 3. GOVERNMENT OFFICIAL: Responsible for creating policies for water management. 4. INDUSTRIAL WORKER: Using water for manufacturing or production processes. 5. ENVIRONMENTAL ACTIVIST: Advocating for sustainable water usage and conservation. Guide Question for the Role Playing 1. What is the importance of each role in water conservation? 2. What challenges and conflicts between different stakeholders? 3. How can collaboration lead to better water management?

Learning targets At the end of this lesson, you should be able to say, "I can"... 1. identify different uses of water; 2. explain how different activities affect the quality and availability of water for human use; and 3. suggest ways of conserving and protecting water resources. With all these water, why is there water scarcity? With a continuously growing population, the demand for water exceeds what is available. It is therefore everybody's responsibility to conserve and protect water resources. What are we then doing to address this major concern? The Philippine Clean Water Act of 2004 (Republic Act No. 9275) aims to protect the country's water bodies from pollution from land-based sources Water use and Management The Philippines obtains its water supply from different sources – rainfall, surface water (river, lakes), and groundwater. The use of water in the Philippines may fall among the following categories: (1) Agriculture; (2); Industrial (3) Domestic/ Household; (4) Recreational; and (5) Aquaculture & Livestock raising 7.22% 0.03% 7.48% Water Use Agriculture 85.27% Domestic 7.48% 85.27% Industrial 7.22% Others 0.03% Water use and Management AGRICULTURAL WATER USE Water use and Management Agriculture uses more than 2/3 or 69% of the water human use, globally. There are two types of irrigation methods: overheard sprinkles and trench irrigation (drip Ir.). Water use and Management INDUSTRIAL WATER USE Water use and Management An estimated 15% of worldwide water use accounts for industrial use. According to the United States Geological Survey (USGS), industrial water is used for fabricating, processing, washing, diluting, cooling, or transporting a product. Water is also used by smelting facilities, petroleum refineries, and industries producing chemical products, food, and paper products. Water use and Management HOUSEHOLD USE Water use and Management Globally, household or personal water use accounts for 15% of worldwide water use. We use water for daily activities such as cooking, bathing, washing dishes, doing laundry, and flushing toilets. The used household water can be treated and reused. Sewers may transport water to treatment plants where water quality is improved for reuse. Water use and Management RECREATIONAL USE Water use and Management Many sports involve the use of water. Swimming, fishing, and boating are the most common examples of activities that use water. Water use and Management Aquaculture & Livestock raising How do you categorize your activities? (1) Agriculture; (2) Industrial (3) Domestic/ Household; (4) Recreational; and (5) Aquaculture & Livestock raising THANK YOU A small step can lead to a thousand miles! Save Energy!
