Chimacum's Science Blogs-

Mr. Gonzalez's Science Classes

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.

Our amazing water quality project has come to an end. Students have been busy the last few weeks sharing presentations of their work with each other, writing final conclusion blogs (#comments4kids), and self-assessing their understandings of the Science standards that most closely fit our project.

Since we are beginning a completely different unit studying physical science students who are not done with any of the above can access any of it from home to finish. Their goal is to have all this work done by March 28 for student-led conferences! Parents don't forget that you can see what we're doing in Science by visiting my HW/Daily work site.

Chimacum Creek, both Forks and Mouth.

Here is a picture of the Pacific Northwest Peninsula. We find it on a map of WA state by looking for the peninsula that looks like a dragon. The dragon's head is where Port Townsend can be found while just south of there, where the heart of the dragon would be, we find Chimacum and Port Hadlock and Port Ludlow. On this image you can see the two forks of our creek. It's the west fork that passes through our campus so that is the one that we get all our data from.

Slightly more detailed view of Chimacum Creek, both forks, as they lead to the mouth.

This image is a zoomed in view of the first image. This one allows a slightly more detailed view of Chimacum Creek, including both the West and East Forks.

My job is dizzolved oxygen wich is the long term for D.O. And dizzolved oxygen is what fish breathe.The best levels are 5.0 and up to at least 18.0 anything below or above is a form of polution .Our hear average is 8.125 and thats great!

PH is short for positive hydrogen and the years average was 6 and that means good! Once again the levels are good .

Turbitity means how clear the water is and the years average is 44.7 and that means its good! Wich is the types time ive wrote so chimucum creek must be good.

Nitrates is a mix of one nitrogen molecule and three oxygen molecules and the years average was 0.3 that means its good man ! This creek is good .

Ammonia is a gas wich can kill alot of fish wich is sad :(

The year average is 1.6 wich is impossible because we've seem fish and this level would mean the fish would be dead see!

Flow rate is the flow of the creek and it's to find the speed of the creek and the speed is 1,972. If it's too fast and too slow it's bad.

Tempurtere is too find the tempature of the creek .If the tempature is too hot or too cold the fishes will die .the year average isn27*c which is alright .

Roses are red, violets are blue, our creek is clean, clear, and cool. Nitrates, Ph and others like DO, lead us to one thing that all of us know. Chimacum Creek is doing great, so jump off your chair and celebrate!!!

That's right Chimacum Creek is absolutely great! If you don't believe so, I'll prove it to you. All the sixth graders in Chimacum divided into water quality jobs and gathered this data:

DO ( disolved oxygen ) average= 8.125 mg/l which is not too high or too low

Ph ( positive hydrogen ) average= 6 which means that our creek is almost pure but slightly acidic.

Turbidity average= 44.7 NTU which means our creek is clear.

Nitrates average= 0.3 mg/l which means that there is enough nitrates for algae to grow but not enough for fish to be effected.

Ammonium average= 1.6 mg/l which is the only average here that is bad.

Flow rate average= 1972.8 gal/s which is slow enough for fish to rest but fast enough for the algae to not grow super big.

Temperature average= 31.13 dergrees F which means the creek is cool. ( As in cold ).

This data proves that Chimacum Creek is doing well. And if this still doesn't convince you, that data is backed by our benthic macros research.

Jac and Aliina from the North Pacific Salmon Collition brought in water samples from the creek that had a bunch of bugs in it. A tool on the moodle showed us a chart of what bugs are tolerant and sensitive. We identified many mayflies which are very sensitive. That means that our creek is clean enough to be home to very sensitive bugs.

So, all of this years water quality research has totally paid off, it lets us know that Chimacum Creek is doing awesome. But, just because we know that the creek is clean and healthy, doesn't mean we can take it lightly. We still need to make sure it stays clean. So please stop doing anything that might pollute it, even litering on land can effect the creek.
