Welcome to another wacky episode of the Wonderful World of Science, starring..Me, Professor Science!!! Do I have a great show for you today! We are going to discuss the water cycle. No, it’s not some new aquatic recreation vehicle. The water cycle is nature’s way of distributing water to everyone and everything on Earth. Water is an essential part of the life cycle. It has a wide variety of functions. Water nourishes plants and animals, and carries impurities away. Water is capable of dissolving many things, and it even helps shape the face of the Earth. Pretty amazing stuff, huh? Just about all of the water on Earth today has been recycled millions of times. The water that was on Earth millions of years ago is the same water that you drink today. And the Earth has as much water today as it always has because of the Water Cycle. But that doesn’t mean we don’t have to conserve water. You see, we’re not really conserving water; we’re conserving the amount of recycling Earth has to do. On Earth, major elements and nutrients are used and recycled in Biogeochemical Cycles. Whew! That was a big word. Basically, a biogeochemical cycle is the Earth’s way of processing natural resources, such as nitrogen, oxygen, carbon, and most importantly — water! Living organisms can use these materials over and over again. Water Cycle Video Quiz © Sunburst Visual Media, a division of Global Video, LLC
Script Water is by far the most common compound found on Earth. About 75% of the Earth is water! That’s right, there is more water than land on our planet. Water even makes up about 70% of the weight of our bodies. All living things require water to survive. Let’s talk about the compound water for a minute. Old H20! That’s the scientific abbreviation for water. Each water molecule has two atoms of hydrogen and one atom of oxygen. The way these atoms combine accounts for the properties that make water so valuable. Water is referred to as the universal solvent because it has a property called polarity that helps break down other compounds. You see, the hydrogen atoms share their electrons with the oxygen atom, which gives the hydrogen side a positive charge, and the oxygen end a negative charge. This polarity causes water molecules to stick to one another. They also stick to molecules of other substances. That’s why water can break down and dissolve other materials so well. That’s why we use water to wash clothes and dishes. SCENE TWO PROFESSOR SCIENCE Water naturally occurs in solid, liquid, and gas forms, depending on its temperature. When we think of water, we usually think of liquid. Snow and ice cubes are common examples of water in its solid form. Water vapor also exists in our air. You are probably familiar with the term “humidity”. It means the amount of water in the air. Water changes form as a result of its temperature. Water freezes to solid form at zero degrees Celsius or 32 degrees Fahrenheit. At 100 degrees Celsius or 212 degrees Fahrenheit, which is commonly referred to as the boiling point, water escapes its liquid bonds and becomes vapor or gaseous. It remains liquid at temperatures in between. So, you see, water is pretty amazing stuff. Water’s ability to change form is what makes the water cycle so efficient. Let’s see how water travels through this cycle. Water is soaked up into the atmosphere everyday. That’s called evaporation. We have all seen what happens to puddles of water after a rainstorm. The sun comes out, and they dry up. Well, the water doesn’t just disappear; it changes form. You can’t see evaporation happening at a normal rate, but when we boil water, we can see the steam rising. This is evaporation at an increased rate. But a puddle doesn’t have to boil to evaporate. © Sunburst Visual Media, a division of Global Video, LLC Water Cycle Video Quiz 43
