another sweet bug!!!cool
This is a scud it is worth 2 points it's tolerant to pollution.We scored our creek after everybody got a microscope and a sample of water then the whole class put in what they found and as a total of the bugs that we found and got 21 points. 21 points is a potentially good water quality but on BIBI we were very low integrity but we have a good creek.When we went to Cispus we went to a creek called Yellow Jacket creek after we came back we saw that the creek that we saw was clearer and it was mostly the same just a litle bit higher so it is a lot different but it's still cool to see bugs AWSEMOME=http://=http://!

Acidic and basic are two extremes thatdescribe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.
The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. The same holds true for pH values above 7, each of which is ten times more alkaline—another way to say basic—than the next lower whole value. For example, a pH of 10 is ten times more alkaline than a pH of 9.
