Water pollution is very serious, it is making are world unsafe in almost every way. Why can't we just stop making water pollution happen? It pollutes are land, water, and are bodies. Marine dumping is another type of water pollution.Some things that take a while to break down.Cardboard it takes two weeks to break down,news paper takes six weeks to break down, and foam takes fifty years to break down. Industrial dumping causes lots of health problems with people that drink water from factory's it causes lung cancer, liver cancer, mesothelioma, and more problems. Some industries use radio active waste. Operations that conduct this produce radio active waste.Oil spills make up about 12% of oil that enters the water, others oils come from shipping travels, drains and dumping.A tank or piping network that has at least 10% of its volume underground. In the atmosphere ,water particles mixed with carbon dioxide turn in to weak acid.Global warming is a process where it takes the green house effect which makes the earth hotter than it should be.farm fertilizer runs into the water we drink by when you put harsh toxic fertilizer on the soil it goes into the water we drink. There are 7 types of water pollution.The types of water that are on the top of the land are oceans,rivers, and lakes when they get polluted bad things happen to are water we drink and the animals we love.tiny little animals live and eat things in water are called microorganisms when their water polluted they have no place to live and nothing to eat. Ground water pollution is hard to get rid of because it is in the water you drink.Nutrients can sometimes be to much and clog you filters.Microbiological live in water and have people,and land animals become very ill.Suspended matter eventually settle and cause a thick slit at the bottom of the water.suspended matter eventually settle and cause a thick slit at the bottom of the water.Chemical water pollution is also a big part in water pollution metals have chemicals in them and if they get water it will pollute the water. There are a lot of dangers when water pollution is near us.when heavy metal parts get dropped in the water it pollutes the water and fish breath water and it get in their gills or shellfish get shellfish poisoning.in the economy there are a lot of choices to prevent water pollution like biological filters, chemical additives, and sand filters.industrial waste can get into water and pollute it so animals the drink the water in lakes, rivers, and oceans and seas. Preventing water pollution can be easy if you know what to do.turn off water to save it, try not to throw things in your sink, toilet, or shower because it clogs and gets in to in sea. dumping things in the water like sewage ,waste ,and nucular waste has been illegal in a lot of countries. Treating water pollution is hard but can be done. the sewage has to be treated a special way it must be it goes through chemicals and other things that help it be not so harmful.Untreated sewage flows in the septic and makes it get worse over time it starts collecting other kinds of bacteria.Lots of fertilizers are used to help grow fruit and vegies the fertilizer goes into the ground soil and pollute the water.The ozone breaks up water waste and pollution it kills bacteria in the pollution. Water pollution is very serious. It could be in your backyard or the ocean you love. Or can kill animals that cant help themselves. So one at a time we can each stop polluting water.

1. The effort force kept going up, the effort distance went .10,.40,.10,.09,.10.The amount of work kept going up, as the we got closer to the fulcrum point it got harder to pull.

2. They help us lift things and do some work for us.

3.It took a lot of figuring out to make it work but then we got it.

1.Newtons first law is Inertia which is if an object is in rest it will stay in rest unless distirbed by a unbalenced force.

2.Acceleration is produced when a force acts on a mass.Or something that is lighter is easier to move than a heavier thing.

3.For every action there is a reaction, or its like gravity. What goes up must come down and a apple must fall from a tree.

1. The lightbulb went on.

2. The washers would fall faster and the lightbulb would go on longer.

3. with all the washers the lightbulb went on but a little longer each time with more washers.

4. That weight can power light.

5. The motor.

7. The weight of 4 washers was 1.2, the weight of 5 washers was 1.4. The weight of 6 washers is 1.5, and the weight of 7 washers is 1.7 . And they all fell 3ft 8 inches.

8. Having more washers.

9. Step one get pegboard, 2 get materials, 3 put black wire on the light bulb holder and then put the red one on to. Step 4 put the washers on the hook, wind them up and drop them. Thats how you do lesson 10.

10.No because you have nothing to hook the wires on.

1. A watt is how you measure power. Its work over time.

2. Well power is work over time, 1 watt is 1 newton meter over 1 second, and power is work over time.

3. Horse power is 750 watts.

4. Yes because the more batteries that you use the more power you have the more power you have more washers that you can lift.

5. When my team and I added more batteries the motor lifted faster and more powerful.

6. On the time graph the line went up and then down, then on the power graph the line kept going up.

7. I would have more batteries.

8. Kinetic energy and heat.

I learned that you can change the mutilated varible and can not change the others. You can change the different surfaces,wieght of the block,surface area,pulling distance ,and pull speed.

I know because the there is a hook on the block that you attach the spring scale and there are different types of surfaces that you can have to pull the block on.

I think that if you pull the blocks on ice the spring scale will be at .1 because if you walk on a table and walk on ice I the ice slippery and the table

When i changed the surface area i got different numbers in newtons.Like .5,.7,and .6. My team and i got table top and thats what we measured.My hypothesis was as the surface area increases the friction force will increase because of the urface type.

My science passion is to learn new things and learn more about animals.

My team and i found out that the motor needed more energy.Beacause the light bulb stayed on for longer and motor ran out of energy faster. And they were both charged for the same time.I think why the motor did not run as fast is because the motor is larger than the light bulb so it needs more energy to power.
