 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

Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.   The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9. Article posted May 14, 2012 at 07:54 PM GMT • comment • Reads 982

It stands for potential of hydrogen (yes i rememberd).what i learned is that 0,1,2,3,4,5 is not so good 6,7,8 is good (7 is sorta the best to get) 9,10,11,12,13,14 is bad anything above 8 is bad because if its not 6,7,8 then the fish will die and we dont want that. There are other jobs other than pH : there is flow rate,ammonia,nitrates,temperature,dissovled oxygen, turbidity         Hope you enjoyed it well see you on my next blog=http://=http:// Article posted March 1, 2012 at 10:16 PM GMT • comment • Reads 1344

The hot water is a pollution to the fish. The hiest we want the water is 41-42. If it gets in the 50's and 60's the fish would die. So would say chimacum creek is doing good. From Mr. G - Temperature is important! Do you know how the other parameters are doing for our creek? Do you think Chimacum Creek is doing well overall? How are the salmon and trout in our creek doing? Article posted March 1, 2009 at 06:00 AM GMT • comment • Reads 1279
 Article posted February 3, 2012 at 03:55 PM GMT • comment (1) • Reads 1558 Name _Nicklas S._____________________________        Date _2-1-12_________________ Water Quality Research Questions Research Notes  What is the parameter? (Write a complete description of it.    Flow Rate is it is the measure of cubic feet per second or gallons per second in a creek or river. Cubic feet per second is expressed: ft3/sec. Flow is a function of water volume and velocity. Stream velocity increases as the streams volume increases. Unless the volume of a stream is the same of the other stream they won't have the same Flow Rate.        How does it affect water quality?   Large, swiftly flowing rivers can receive pollution discharges and be little affected, whereas small streams have less capacity to dilute and degrade wastes. Stream flow determines the kinds of organisms that can live in the stream, some need fast flowing areas others need slow, quiet areas.         How is it measured? What levels are good? What levels are acceptable? What levels are bad?    Flow Rate is measured in cubic ft. per second, or "ft3/sec". Good levels of ft3/sec depends on what lives in the stream. Bad levels are pretty much whats too fast for any fish, macroinvertebrates, ect. Acceptable levels also differ to whats is living in the stream, there really is no good/bad levels, it just depends what the things in the stream need.       How does this parameter affect fish? How does this parameter affect humans? How does this parameter affect vegetation?    Flow Rate affects fish VERY much, fish could be washed away, etc. Fish do need either fast streams or slow streams. Fast-moving streams generally have higher levels of dissolved oxygen than slow streams because they are better aerated. This affects humans because streams with a higher flow can wash away eutrophication, waste, etc. Article posted February 3, 2012 at 03:55 PM GMT • comment (1) • Reads 1558

You measure D.O with a probe , you put the sensor in the water & it gives the the amount of D.O . Turbidity Turbidity is Based on how clean or dirty the water is , high turbidity can kill fish and fish start to abandon habitat and plants will die . Chimacum creeks average of turbidity is in the 30's . Ammonia Ammonia can be found in many cleaning products .Ammonia is a colorless gas & strong smelling . The formula of Ammonia is NH3, means it consists of one atom of nitrogen and three atoms of hydrogen . Nitrates Nitrogen is In the air ,and is a gas . It can cause a sickness called Methemogoblin . Plants can not use nitrates it's not good for them . N2 is 78% of air . Flow rate Flow rate is based on how fast or slow the water is going .Flow rate is measured by a probe with a propeler . Air flow rate is one other type of flow rate . Flow rates average is 1.3 cubic meters per second which is good . Temperature temperature is very important to water , if its to cold or to warm fish can die. It takes longer for deeper water to heat up because there is more water . In the summer if the temperature doesnt get over 50 degrees ferenheit then the fish will be fine . Ph Ph is Positive Hydrogen , Which is H2O . Ph ranges from 0-14 , 0-6 is Acidic , 7 is Basic (well, 7 is pure H2O, or water, and above 7 all the way to 14 is basic and alkaline because they mean the same thing. - From Mr. G) , And 8-14 is Alkaline ,Human blood is basic so about a 7.3 or 7.5 .

We measure the dissolve oxygen and make sure there is enough for the salmon to breath and live normaly.d.o. Is a simple yet important job.
