 We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world. Mr. G's Blog Mr. G's Class Facebook Page

When you charge a battery it puts more stored energy in your battery then your battery will be able to be used again if your battery is rechargeable. if your battery is not rechargeable your battery is know useless. When you use a battery it goes from stored enegy in the battery to chemical energy. Article posted April 26, 2010 at 06:01 PM GMT • comment • Reads 1450

This pamphlet will provide you with information about how fresh water pollution can be caused and prevented. What is water pollution? A. Fresh water pollution is when there is runoff or people dump trash or oil into the water. The water is then polluted. What are some of the sources of pollution? A. Oil is one source of pollution, and from the ships dumping large amounts of waste into the ocean is another. What are some of the consequences of water pollution? A. Animals from the ocean and land that drink the water get sick and could die. They die from people dumping waste in the water. What can be done to improve the quality of water after it has been polluted? A. Pick up trash around the water and recycle properly. Get people educated about water pollution. What are some actions that can be taken to help prevent water from being polluted? A. Recycle properly. And add in less household cleaners and chemicals. Don’t throw trash from your boat into the water. What are nitrates and how do they get in are water? A. Nitrate is a natural compound present in all eco system. It is one of the chemicals essential to plant life but too much can be a problem for plants and animals. It is also a component of chemical and mature based fertilizer. Nitrates can enter watercourses and ponds from sources such as areas of high fertilizer use, livestock feedlots and pastures, and sewage treatment areas. What effects do high nitrates levels have on people? A. Well it caused blue baby syndrome that put big effect on people. . What is considered to be the safe level for nitrates in drinking water? A. Under 10 mg /l no. What should a person do if there are high nitrates in their water supply? A. If you are pregnant try to avoid drinking water on a daily basis from that source. You should call your water supply company right away. What can be done to prevent nitrates from entering our water supply? A. Reduce the high fertilization dig tile drains deeper in the ground. This will prevent nitrates in your water. What are point and non point sources of pollution and what are the differences between the two? A. A point source of pollution is when you know what’s causing it. A non point source is when you don’t know what causing it. The difference is that one can be traced and one can’t. We hope that you try and get people educated about fresh water pollution because it is becoming a huge problem. Article posted November 2, 2009 at 06:17 PM GMT • comment • Reads 522
