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.

IN THIS PAMPHLET YOU WILL FIND WHAT WATER POLLUTION IS, HOW IT AFFECTS US, AND HOW CAN WE PREVENT IT. YOU WILL ALSO LEARN ABOUT NITRATES, WHAT AFFECT IT HAS ON US, WHAT WE WILL DO WHEN THERE’S TO MANY NITRATES IN OUR WATER, AND WHAT CAN BE DONE TO PREVENT THIS.
What is fresh pollution?
Well first of all the definition for water pollution is: polluting the natural environment is when waste products or other substances change
Physical the thermal or biological characteristics of the water adversely effecting living species and reducing the water’s beneficial uses.
What are the sources of freshwater pollution?
One of the main sources are human influenced pollution’s. These can relate to trash because it can fall into the water. Or car exhaust because it evaporates and then it rain’s and the rainwater gets carried into rivers or oceans. Another one is: fertilizers for crops that are in the field, than it rains and washes the fertilizers in to creeks, which eventually get to the oceans.
What are the consequences of water pollution?
Some of the consequences are very bad! Many things die and many things are destroyed. For example: the Exxon Valdez oil spill in Alaska. This oil spill killed eagles, aquarium life, murrelets, crows, gulls, otters, and much more life! Ever since this has happened necessary precautions have been taken.
What can we do to improve the water after it has been corrupted?
We can pick up trash if seen, we can throw away our trash away properly so it doesn’t pollute. And we can minimize our resources consumption.
What can we do to help prevent water pollution?
We can educate young children to help throw away trash, so in their generation will lean and it will keep getting passed down to the next generation and so forth. And we can encourage people not to pollute also.
What is a nitrate and how does it affect our water supply?
A nitrate is a natural compound present in all ecosystems. It is one of the chemical’s essential to plant life, but to much can be a problem for plant’s and animals. It is also a component of chemical and manure based fertilizers. Nitrates can enter water sources and ponds from sources such as areas of high fertilizers use, livestock feed lots, and sewage treatment areas.
What affect does high nitrate levels have on humans?
Excessive levels of nitrates in drinking water are very bad. Some of the consequences are: serilous illness, stomach acks, and sometimes death!
What is the standerd level in drinking water?
Drinking water levels whitch are conciderd “ safe “ for short term exporsures: for a 20 lb baby it is conciderd a liter a day.
What should a person do if there is too many nitrates in there water supply?
They must take steps to reduce the amount of nitrates, so they are constently below that level
What can we do to keep nitrates out of our water?
Your wells need to be isolated from contamination and from the surface damage. Make sure it is in good repair to prevent surface from coming in.
What are point and non point sources of pollution, and what are differences between the two?
Point sources are sources of pollution that are obvious, and non point is pollution that you can’t see. The difference between the two is that: point source you can point to it. And non point you can’t point to it.
