Have An AMAZING summer,guys!!!


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.

Conclusion Blog

All of the blog articles that i have done for science,have led to this one.Water quality,creek jobs,water pollution,etc etc.so,heres what i figured out.......


WATER QUALITY


water quality is like the creek jobs,but it is how water is doing as in just water.The levels of toxins,acids,etc etc.this is partly why we went down to the creek!


CREEK JOBS


the creek jobs are testing the levels of amnonia,turbidity,nitrates,dissolved oxygen,and more.we used tools to go down to the creek and test the water.I was turbidity which is the testing of cloudiness and clearness of water.So,we just check for the cloudiness because sometimes thatmeans that there are acids or dead plants in the water.


WATER POLLUTION


water pollution sorta ties in with the creek jobs.because some of the ways to get water polluted is some of the things we are testing for.like acids,amnonia,etc.it can be caused by fertilizer leaking in the water,sewage,garbage,and toxic chemicals.


 


HOW IS CHIMACUM CREEK DOING??


chimacum creek is doing very very well because all the levels of things like turbidity,dissolved oxygen,etc...exept for amnonia which is bad for the water and makes it polluted.the high level was thought to be a mistake tho.....


 okay here are the creek lvls


D.O


D.Os average for this year is 8.125 MLG/L.this is good because it means our creek  doesnt have to much D.O and it doesnt have  to little D.O.


Nitrates


Nitrates average for this year is 0.3 mg/l this is good because if our creek has too much nitrates,the alge and the other plants will grow too much.


Turbidity-meh job!!!!


turbiditys average this year is 44.7 NTUs.this is relatively low and that is good for our creek because that means our water is clear.If the was is high in turbidity,that means that the water is muddy,foggy,or just unclear.if the water is foggy,that could mean that our water has acids,dead plants,mud,or something that is bad for our water.


PH


the average this year for ph is 6.this is great for our creek because if it is under seven it is acidic.if it is over seven t is alcoline.


Ammonia


the average level for ammonia this year is 1.6...this is the one that mr.g thinks is likely a mistake because it is very high and it means our creek is very high in ammonia and all the other levels are great.


Flow Rate 


1972 GPS is the average flow rate for this year.this is good for our creek because if the flow rate is to  fast then the fish cant rest and then they would be very tired.but he level is good because the fish can rest and they wont get pulled with the stream.


 Temperature


the temperature level this year is good.37.13 F.this is good because if iti is too hot then the fish eggs would overheat.if it was too cold,they would freeze.
