Down the DDDrraaaiiinn!
With Down The drain, I learned that water doesn’t get smaller (which I thought it did.) I wanted to be sure so did a test. So I just had to do the experiment. I did this by putting water in a plastic cup and filling it with water about half way. Then, I put it in the freezer and I marked were the water was. After 24 hours, I checked the cup. The water had actually raised about an inch! As you may see by now, I like science. I like to prove things and be sure. Down The Drain showed me this and more. My hypothesis is “People in the ocean use almost as much as the people in the desert.” First of all, people in the ocean have a lot of tourist. Secondly, you can’t drink salt water. People in the desert use a lot of water and I think people close to seashores also use almost as much as the people in the desert. My prediction is that people in Tucson, AZ use almost as much water in Charleston, South Carolina. My hypothesis was wrong. The states near the ocean use less that the people in the desert. That is because in the ocean there is more precipitation than since of all the ocean water. When the water precipitates, it gets clean and purified. My prediction was also wrong. Charleston uses only 90 gallons a day in average. I learned a lot in Down The Drain! Did you know that you could get 271 daily baths with one rainstorm! Also washing a lawn can take up to 300 gallons of water! Wow!! An old toilet (standard flow) can waste up to 8 gallons! A standar flow shower head can waste 50 gallons! “But it isn’t much!” you say. Not much? gallon by gallon, liter by liter wastes a lot of water. I wasted 100 gallons a day. 901.75 gallons a week! I knew that raindrops were not tear-shaped but I didn’t know that water evaporated quicker in Colorado than at the beach. I bet you didn’t know that more things could be dissolved in water than in sulfuric acid. Or I bet that you didn’t know that if you boiled water from the Great Salt Lake an inch of salt would be left!
Up there are graphs showing how many gallons and liters each of our class member uses. To use the graph, look at the initials in the graph. Then look in the spread sheet and locate the same initials. There it shows the number of gallons and liters each person used. I was in the middle so that was good. I think this mean that I drink, eat and take showers almost as much as other classmates. Remember, water is life! |
