I AM MEDUSA! I CAN PARALIZE YOU! MWAHAHAHAHAHA=http://!!!

WARNING: Do not look directly into eyes. Will paralize.

What are some ways to use elastic force to move a cart? Well, I came up with a smarticle idea. ( ok. So mr. G gave me the idea! So what. Don't you give me that look!) so my smarticle idea is that I will take the rubber band and break it so that it is one long strechy string and I will tape it to two nice solid objects. Then I will place the cart in front of it and then I will pull the cart back and let it go. I have made my very own smarticle slingshot=http://!

I will (i said will) be an actress. Even ask Alex. He wants to be a movie director and i asked him if i could be the lead actress in his first movie he ever professionally directs and he said sure. Yay=http://!!!! It will be awesome. So in a couple years you will turn on your tv's and you will see me.

This blog is directed to those kids who need help in class-social studies, exploratory, language arts, science... Anything, really! Leave me a comment telling me you are coming and i will get back to you. Then on Mondays we'll meet at the elementary school library. This will go on for only a couple of weeks, so hurry up!

See ya there!

Well, first you insert the battery into the charger and you plug it in and electrical energy goes into the battery and turns into stored chemical energy. Then when you hook the battery up to the light as it runs through the wires it becomes electrical energy again and as it enters the light it becomes light energy and heat energy. When you hook it up to the motor it does the same thing except it turns into mechanical energy instead of light and heat energy.

I only know a few things about batteries, and here they are.

1. If you put the end of a 9 volt battery on your tonge it will shock you
2. It contains battery acid and copper
3. If you break a battery open and it gets on your skin, it will burn your skin.
4. They can be so small that they can sit on a dime, and so big they can power a car.
5. They are used for most modern day electronics
6. Some are rechargable!

What I would like to know about batteries.
How do they work?
When was the first one made?
How big is the worlds biggest battery?
Who discovered how to make batteries?
How do you make them?

What I learned about batteries.
1. How to make batteries
2. Who invented batteries
3. How long a battery would stay on based on different charging times
4. That copper sulfate solution is EXTREMALLY toxic (WARNING: do not drink)
5. How to make car batteries...See Serenity's blog
6. When the first battery was made
7. How big the biggest battery ever was
8. We use more energy now than in the 1930's (they used aprox. 1.4 killowats a day!)
9. Batteries can be super small but still generate a lot of electricity
10. How energy changes as it goes from the charger into the battery into the device the battery is powering (electrical energy, stored chemical energy, electrical energy, light + heat energy or mechanical energy.)

The score for Yellowjacket Creek is 25.
The score for Chimacum Creek is 21 (according to period 5 and Mr. G.) this is a awesome score. This means that our creek is pretty healthy. We found quite a few intolerant and very intolerant macro invertibrates.
The creeks are scored like this:
Very intolerant-4 points
Intolerant-3 points
Tolerant-2 points
Very tolerant-1point

ARE YOU TIRED OF WATER POLLUTION?
If you are tired of water pollution, and want a change, then here are a few things to help you understand water pollution.

What is water pollution?

Water pollution comes in many forms. The six main types are:

Surface water pollution. This is when the waters on the earth's crust become polluted.

Groundwater pollution. This is when the underground water, often used for drinking and other household things, becomes polluted, often by pesticide run-offs.

Microbiological water pollution. This is usually a natural form of water pollution. It is caused by microorganisms such as bacteria, viruses, and protozoa.

Chemical water pollution. This is caused by industrial and agricultural chemicals that run off into nearby streams, rivers, etc.

Suspended matter. This is when particles in the water have molecules that are to big to mix in to the water's molecules. This creates a layer on the bottom of the creek, river, etc, harming the fish and other marine life that lives there.

Nutrient water pollution. This is when fertalizer or other nutrient-filled substence goes into the water and causes excess algae and/or weeds grow. This causes many different problems. The weeds use most of the oxygen in the water

What are some of the sources of water pollution?

According to http://www.water-pollution.org.uk/,
"Farmland that is irrigated and treated with chemicals in the form of fertilizers or pesticides"

"Industrial processes produce toxic waste containing heavy metals."

"construction industry is also at fault for contaminating our water resources with cement, lubricants, plastics and metals."

"Natural catastrophes are the cause of water pollution effects as well."

"The growth of algae due to food items, feces, or urea in the water source is also a source of water pollution."

"Littering on the land or on the water is a source of water pollution. Debris tossed onto land eventually makes its way into storm drains and then returns to surface water."

What are some of the consequences of water pollution?

Water pollution effects all of the water that we use every day like drinking water, hose water, etc.

The pollution effects everyone and everything. If the fish get sick, the animal that eats it will get the sickness, too. Then if that animal gets hunted, then the people who eat it will get sick also!

Diseases can get spread from the polluted water when drank.

Acid rain contains harmful particles that can hurt the fish and other marine things, including the plants.

Pollutants will cause changes in the water's chemistry. It effects acidity, tempurature, and conductivity.

How can you improve the quality of the water after it has become polluted?

There are many different ways to improve the quality of the water. Industrial factories purify sewage before sending it out for people to be reused.

Denitrification is a ecological approach on water pollution. It stops nutrients from contaminating the groundwater. When the oxygen level is low, a certain type of bacteria turns the nitrates into gasses such as nitrogen, nitrous oxide, or nitrogen dioxide.

Sewage is a form of treatment that is often used for only one building. Raw sewage from the property it belongs to flows into it. It separates the solids from the liquids. Solids are separated by density (heavier particles on bottom, lighter on top). Biological processes are used to degrade the solids. The liquids then flow out into a land drainage system and the remaining solids get filtered out.

Some evidence I found in my research that Mount Saint Helens will someday rebuild itself to look like what it did before the May 18, 1980 eruption is the ever-growing lava dome. In about a century or two, if an eruption doesn't destroy it, the lava dome may reach the size of the space blown off by the eruption and may grow even bigger
