provide drinking water for humans, this experiment was performed to determine if water velocity affects the health of a stream. For our purposes, water heath was determined by concentrations of dissolved oxygen. We predicted that areas of higher water velocity would have a lower chlorophyll a concentration and higher dissolved oxygen concentration. We collected six samples of water from Wild Basin Preserve in Austin, TX, three from areas of still water and three from areas of running water. We measured
Fresh Water The earth has many different natural resources that it is made up of. Some of these resources include oxygen, soil, food, and most of all water. However, one of them is increasingly becoming scarce and it is a problem that not everybody is aware of. This resource is water, but not just regular water or salt water, fresh water. The earth is made up of 70% water. Out of that 70%, only 2.5% is fresh water which is mostly locked up in ice caps and glaciers. The amount of fresh water on earth
management of our water resources which worsen the drought. The mere idea of running out of water is not to be taken lightly, only a small amount on our planet is safe for human consumption; keeping that in mind Californians must face the necessity to rationalize water in order to cope with the concurrent crisis. The practice of rationing will help maintain water levels. The expected result of this calamity is water shortages and a major impact in the agricultural level across our entire state. The
Child Hood Field Day. I thought that must be a hundred degrees, as I waited for Mrs. Cailler, our school principal, to shout into her microphone. “GO!” I heard, and started to run. Even though it wasn’t a race, I was young, and wanted to zoom around the track like 6th graders could. Lea came up beside me and she was already sweating like crazy. “I love field day, only I don’t like the hotness” I said, panting. “You mean the heat, right?” She corrected me, as she always did. We had only
that are harmful to our environment, for example; water pollution. Pollutants change the pH balance of the water sources they infest, which in large cases is dangerous to the plants and animals that both live in that water source and rely on it for survival. Industrial activities such as mining and manufacturing produce waste that make the pH balance of water acidic, while in suburban areas the waste produced and the activities that affect the water sources generally make the water more alkaline. This
California get its Water? Introduction The Earth is a huge planet this is covered by 70 percent water. Astonishingly from this 70 percent the human population can only use 1 percent of the world’s water the rest of it is salt water, frozen, or in some way unattainable (Santa Clara Valley Water District, 2016). Humans have found many different ways to obtain this 1 percent of fresh water they need, but the techniques vary depending on location. In San Jose, California we obtain our water from 3 major sources:
originate from. Should we utilize non-renewable assets or put resources into new and imaginative renewable vitality sources? Our reliance on outside oil puts the U.S. in an exceptionally powerless position on both the political and sparing fronts. Incalculable studies have been led supporting both contentions. While our surroundings is a noteworthy thought for figuring out which sources to use, the monetary ramifications should likewise be weighed. Renewable vitality sources could last uncertainly
SPORTS NUTRITION PAGE: H: EAT SMART, RUN BETTER SH: SPORTS NUTRITION FOR RUNNERS Healthy-eating habits are the foundation of a good running routine. When you’re running faster, and going for longer, you need to make sure you’re both well-hydrated and well-fuelled. When you’re energised you’re able to run faster, burn more calories, and get fitter, faster. In this guide to sports nutrition we take you through the key food groups, why they are important to runners and athletes and which foods
Water scarcity is a global concern, and that means there’s even a problem in our own backyard. While it may be difficult to put yourself in the shoes of an African child struggling to find fresh water, it’s important to understand that water scarcity affects everyone, even here in the United States. Water covers approximately seventy percent of the Earth surface, but less than one percent of that is available for human use. The world must share this small amount for agricultural, domestic
