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.

What I learned about friction

I learned that without friction when we tried to stop after walking, running, driving, etc. you would just keep sliding until you hit something.
I learned that friction is very helpful with everyday tasks. There would be lots of car crashes and people getting hurt without friction.
1. We measured friction with a 2.5 Spring Scale and a 10.0 spring scale. We pulled wooden blocks across different surfaces types to see how friction would change on each surface type.
2. Then we pulled more then one block across different surface types to see if the friction would change.
3. Last, When changed what side we would pull the block across the surface types to see if the friction would go up or go down.
The spring scale was measuring friction force because the force is pulling the opposite way that you're pulling.

What I learned about Batteries

I learned that batteries can be recharged. I also learned that the longer the batteries got charged the longer you would be able to use it. I learned that you don't need copper sulfate or any metals to make a Battery. You can make batteries out of Lemons and even Potatoes!

I learned that there is no good level of DO.
I learned that our creek is slightly acidic.
I learned that our creek turbidity level is great and good for the fish.
I learned our creek has a good nitrate level and the creek can not harm any fish.
I learned that our creek has a very bad Ammonia level. There is not a Ammonia level that is good.
Our creek has a good speed that is Slow enough for fish to rest when they need to. And Fast enough so that Algae can not grow very big.
I learned that our creek has a very bad Ammonium level.
I learned that our creek has a good fow rate that is fast enough for algae not to grow to big and slow enough that fish can rest if they need to.

HOW IS CHIMACUM CREEK DOING?
Dissolved Oxygen
|
What is this year’s average D.O.?
8.125
What does that mean about our creek’s D.O. levels?
That means that there is a good level of DO that is not too high and not too low.
|
pH
|
What is this year’s average pH?
This year’s average PH is 6
What does that mean about our creek’s pH levels?
That means our creek is slightly acidic.
|
Turbidity
|
What is this year’s average turbidity?
It is 44.7 NTU
What does that mean about our creek’s turbidity levels?
It means that the creek turbidity level is very clean and grt for fish.
|
Nitrates
|
What is this year’s average nitrate level?
This year’s average nitrates level is 0.3
What does that mean about our creek’s nitrates levels?
That means that our creek is at a very good nitrate level that is at no risk of causing harm to the fish.
|
Ammonium
|
What is this year’s average ammonium level?
This year’s average Ammonium level is 1.6
What does that mean about our creek’s ammonium levels?
That means that our creek has a very bad level of Ammonium.
|
Flow Rate
|
What is this year’s average flow rate?
1,972 gallons per. second
What does that mean about our creek’s flow rate levels?
That means that our creek has a good speed that is slow enough for fish to rest when they have to. And fast enough so that algae can not grow really big
|
Temperature
|
What is this year’s average water temperature?
37.13
What does that mean about our creek’s water temperature levels?
The air tempature is 44.35

Dangers: People can step on them. Eroision can even be a danger because it can bury the eggs. Wild animals are dangerous salmon eggs also. Fisherman, Horseback riders, loggers, livestock, and even the casual hiker can be dangerous to the salmon eggs.
Needs:They nned cool clean water to survive. They also need trees and brush along side of the river to provide shade which keeps the water tempature cool enough for the eggs.The trees and plants also help prevent soil erosion which could sometimes smother the eggs.
Description: Small red round eggs with little black dots (eyes).

Who will win??!!

Okay, Yellow Jacket creeks Score on how clean it is.It got 25 points. Our score (Chimacum creek) Got 21 points, I know bummer right? But don't worry how clean our creek is going up all the time. Both of the creeks put up quite a fight the scores were very close as you can see.
The scoring criteria is easy to understand. First,each group got together and started to plug in microscopes to the computers,We used a program called "Mixscope" so we could see all of the tiniest parts on the computer screen.We took twissors and tried to find bugs in the little samples Mr.G provided for us.Then,we took snapshots of the bugs in the water.Everyone tried to identifie each bug.Also we added up the total score of our bugs. If you red my last blog you will understand how we scored them thanks for reading my blog.

Mt.Saint Helens

I don't think that Mt. Saint Helens will ever grow back to the orginal shape and size. It almost lost half of itself In the 1980s explosion. Its supposed to eroupt in in the next two hundred years and even then it would blow all of the dirt and rock off again.
