What I learned about friction -- 05-14-12

2012-05-14T14:21:08-05:00

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 -- 04-09-12

2012-04-09T15:02:54-05:00

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!

Planting trees! -- 01-27-12

2012-01-27T15:06:04-05:00

We went on a field trip to plant trees in Discovery bay. It was fun I planted six trees and we even got to name them! It was by a creek called Snow creek. It was so fun! Our teachers name was Chauwnce(Chawn Cee) I don't know how to spell it hahahahaha. Thanks for having us plant trees!

Sam severn Fry -- 01-12-12

2012-01-12T15:16:51-05:00

Needs: Zooplankton until they grow larger. Then they will need larger aquatic insects.

Dangers: Mergers and great blue herons.

Discription:Fry are small and have tiny goldish lines all the way down their body. They travel in large schools of fish.

Sam Severns Alevin -- 01-04-12

2012-01-04T15:22:00-05:00

Dangers: Spawning Adults, Gulls , Dippers, Sculpins, And Trout all feed upon young Alevin.

Needs: Yolk sac

Discription: Alevins are usually small and a little orange colored. They have a "Yolk sac " on the front of their body kinda below their mouth. It will feed them for about a month. It contains Protein, Sugar, Minerals, and Vitamins.

Sam Severns eggs -- 01-03-12

2012-01-03T15:08:50-05:00

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??!! -- 11-06-11

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 -- 11-04-11

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.

Check out this bug! Its a scud. We took this photo November 1,2011. This is how we scored our bugs: Very intolerant (uncommon)= 4 points These are not uncommon in clean waters though, intolerant (kinda common)= 3points, Tolerant (common)= 2 points, Very tolerant (very common)= 1 point(s).

Water Pollution -- 10-11-11

2011-10-11T13:56:34-05:00

The worls is at risk! Read on...
What is water pollution?
Water pollution are Oil leaks,Sewage,Landfill sites,And Human waste.Water pollution is extremley bad for our enviroment.These are some types of Water Pollution: Surface water pollution,Groundwater,Microbiological,Chemical,
Oxygen Depleting,Nutrients,And Suspended Matter.

Surface waters resources of the earth. They are found on the exterior of the earths crust.
Oceans,Rivers,Lakes.These waters can be polluted in a number of ways,and this is called Surface Water Pollution.
Alot of the earths water is found underground in soil or under rock structures called Aquifers. Humans often obtain drinking water,and build wells to access it.When this water becomes polluted it is called Groundwater Pollution.Groundwater Pollution is often caused by pesticide contamination from the soil,this can infect our drinking water and cause huge problems.
Microbiologiacal water pollution is usually a natural form of water pollution causedby microorganisms.Many types of microorganisms live in water and cause fish,land animals and humans to become ill Microotganisms such as: Bacteria,Viruses,Protozoa.
Serious diseases as cholera come from microorganisms that live in the water.These diseases usually affect the health of people in poorer countries,as they do not have the facilities to treat polluted water.
Idustrial and agricultural work involves the use of many different chemicals that can run-off into water and pollute it.
Chemical water pollution.
Metals and solvents from industrial work can pollute rivers and lakes.These are poisonous to Run-offs of these pesticides can cause water pollution and poisen aquatic life.Subsequently,birds,humans and other animals may be poisoned if the eat infected fish.

Petroleum is annother form of chemical polluted that usually contaminates water through oil spills when a ship ruptures.Oil spills usually have only a localized affect on wildlife but can spread for miles.The oil can cause death of many fish and stick to the feathers of seabirds causing them to lose the ability to fly.
Suspended Matter
Some pollutants do not dissolve in water their molecules are to big to mix between water molecules.This material is called
Particulate Matter and often be caused by water pollution.
The suspended particles eventually settle and cause a think silt at the bottom.This is harmful to marine life that lives on the floor of rivers or lakes.
Biodegradable substances are often suspended in water and cause problems by increasing the amount of anaerobic microorganisms present.
Toxic chemicals suspended in water can be harmful to the development and survival of aquatic life.
Nutrients
Nutrients are essential for plant growth and development.
Many nutrients are found in wastewater and fertilizers,and these can cause excess weed and algae growth if large concentrations end up in water.
This can contaminate water and clog filters.
This can be damaging to aquatic organisms as the algae use up the oxygen in the water,leaving none for the surrounding marine life.
Oxygen Depleting
Microorganisms that live in water feed on biodegradable substances.When too much biodegradable is added to the water,the number of microorganisms increase and the available oxygen.This is called oxygen depleting.
When oxygen levels in the water are depleted, relatively harmless aerobic microorganisms and anaerobic microorganisms begin to thrive.Some anaerobic microorganisms are harmful to people,animals and the environment, as they produce harmful toxins such as ammonia and sulfides.
How will I help to not pollute?
Pick up garbage that is on trails and in the forest. Also You should pick up after you dogs so there isn't dogs scat everywhere.
