3. Introduction This is our presentation about water. Here we are going to show you many things about water like Definitions, uses of water, pictures of water, videos of water, news, comics, graphics, problems and solutions of water, ways people use water, and G.O. We hope you like it and learn many things about water. Have many fun In this presentation you are going to see another's natural resources like hydrogen and oil.

4. Definition Water in three states: liquid, solid (ice), and (invisible) water vapor in the air. Clouds are accumulations of water droplets, condensed from vapor-saturated air. Water is a chemical substance with the chemical formula H 2 O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

5. H2O Water in three states liquid, solid (ice), and invisible (water vapor) in the air. It should be cared. It doesn't last for ever. types polluted salt drinking Water pollution is the contamination of water bodies (lakes, rivers, oceans and groundwater).Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. 97% of the earth water is salt water. Salt water is not drinkable because of the salt it contains. Drinking water or potable water is water of sufficiently high quality that can be consumed or used with low risk of immediate or long term harm. we can prevent these things by not throwing our garbage on the floor or by recycling. Uses There are a lot of uses but some are good and some are bad. Drinking Recreational Personal Drinking water or potable water is water of sufficiently high quality that can be consumed or used with low risk of immediate or long term harm. We use water in pools and when we go to the beach or jet ski etc… When we take showers, wash our hands. environmental W ater tests, cleaning plates, boiling,fishing etc…

6. Hello Hello i hear what you are sadeding about water, so water is important? Yes grandson, if we don't have water we will dead, water is very important Nothing Yestorday i see a program about save water

21. Problem and solution

22. Ways people use water Water resources are sources of water that are useful or potentially useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water. 97% of water on the earth in salt water, leaving only 3% as fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is mainly found as ground water, with only a small fraction present above ground or in the air. Fresh water is renewable resource, yet the worlds supply of clean, fresh water is steadily decreasing. Water demand already exceeds supply in many parts of the world and as the world population continues to rise, so too does the water demand.

23. Why do we need water Water is probably the most important resource on earth. We need water to grow and stay alive. In fact, we could only live for a few days without drinking water. We also need water to grow plants and care for animals, cook our food, bathe and brush our teeth, flush the toilet, and wash our clothes.

24. Why do we need to save water Look at the picture of earth. Most of the earths surface is covered in water. You might think that there is plenty of water for everyone to use. But did you know that most of the water on earth is ocean water? Ocean water is very salty. You cant drink it or use it for growing plants, cooking food, bathing, or washing clothes. The water we use for these things is called freshwater. It comes from rain or snow that falls in rivers and lakes. It is also found stored in rocks beneath the ground. Some people don't have enough fresh water where they live. It is important for everyone to conserve, or save, water so that there is enough for everyone

25. What are some ways to conserve water In the united states, each person uses about 50 gallons of water a day. When people use water, they often waste a lot. Very large amounts of water go down the drain without being used. To conserve water, try some of these ideas:

27. Water cycle The earth has a limited amount of water. That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle". This cycle is made up of a few main parts: evaporation (and transpiration) condensation precipitation collection
