 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://!

 About the Blogger 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. |
