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.

water pollution is very bad for the earth.so why do we need to stop water pollution? well,one of the reasons is because it can kill sea animals.another reason it is bad is because if we don't start taking care of the earth we will not have clean water to drink or healthy fish to eat.



what are the causes of water pollution? well,some of the causes are sewage,waste water,marine dumping,oil pollution,radioactive waste, global warming,and underground storage leaks.



how do we treat water pollution?we can treat water pollution by stop letting litter getting into are lakes oceans and rivers.this is a big part of what causes water pollution.





what is the danger of water pollution?some heavy metals from industrial processes can accumulate in nearby lakes and rivers.these are toxic to marine life such as fish and shellfish.it is also toxic to the humans who eat them.



what can we do to prevent water pollution? we can stop water pollution by conserving water by turning off the running faucets when you are brushing your teeth.this helps preventing water shortages and reduces the amount of contaminated water that needs treatment.

1. the effort force went down.



2. they help us do less work.



3. the motor did less work and lifted more washers.

1. The more washers that you put on the paperclip the brighter the light bulb will be.



2. It lights up.



3. The more washers that go on the paperclip the brighter the light will be.



4. The washers falling make the motor make energy for the lightbulb .



5. The more work that got done the brighter the lightbulb.



6. The washers falling makes the motor makes energy for the light bulb.



7. I saw the more work that got done the brighter the light bulb will be.



8. When the washers dropped the motor did lots of work.



9. Use the work that was recorded in the graph.and then you time how long it takes for the washers to reach the ground then you divide the work by time.



10. No because we chargedn the battery by putting it in copper sulfate.

1. one watt is equal to doing 1 newton-meter of work in one second.



2. It describes The power.



3.1 horse power is 750 watts.



4. Yes needs more energy



5. The motor lifted more as me added more batteries .



6. Power goes up and the time goes down.



7. A newer motor.



8.Yes because I think that all of the energy was used by the motor.

1. We found out that the shorter the string,the more washers the motor could lift.



2. The motor can lift 4 to 7 washers at the most.



3. It pulled 2 newtons.

1. I learned that you can have more that 1 varrible.



2. When you measure speed you get friction from it.



3. it would make it slide easier.



4. When we changed the surface area we got different numbers in newtons.Are surface type was fine sand paper.

1. pull the cart with the rubber band.

2. stretch the rubber band and it will make the cart go faster.

3. gravity.

4. gravity goes down.

5. the reson things have different weight is because of the mass.

6. strength and energy

7. when i changed the amount of washers the weight got bigger or smaller.

The motor required more energy than the light. we gave the battery a 3 minute charge. then we conected the battery to the light. then, we gave the battery another 3 minute charge. then, we found out the results for the motor. the motor didin't last as long as the light. we found out that the motor took up more battery by recording the time.
