Tuesday in Class October 18th

Tuesday October 18
Today we did an assignment out of our books about the three main cycles, they were the water cycle, the carbon cycle, and the nitrogen cycle. Some people were allowed to check out books over night if they didn't get finished during class. This is due the beginning of class Wednesday.
Some things that I think are good to know are:

-how waste water is filtered and the separate steps taken to purify it

-how plants and animals get nitrogen

-what the difference between free nitrogen and nitrogen already processed by bacteria is

what I wondered was what happens if there is too much or too little free nitrogen in the air.

Today we went to the pond to take a temperature test of the water. We also collected water samplesto do later water quality tests. After recording and collecting our samples we came back to the school.

On Wednesday this week we took our first real test. It required alot of study if you wanted to do very well on it and who wouldnt? But there were some questions on the test i didnt know, but i took an educated guess. These were the questions:

What is the PH of battery acids?

Which one of the following is not a scientific base unit
A. Second
B. Meter
C. Feet
D. Kilogram

I also thought the base unit question were challeging. You just had to remember the saying:

Today we tested the dissolved oxygen in five water samples. We did this with the probe. After we got the five readings we answered two questions on what would happen if there was to much or to little dissolved oxygen in the water, and what dissolved oxygen did.

In our class we finally got to the point of taking a test. As we prepared for our test we were given a study guide. This study guide had the majority, if not all of the questions on it that are going to be on the test. I thought this was very convenient and will help improve test scores. We were able to work on the review which added up to be a little under 80 questions. After we finished the review we went over it, correcting wrong anwers and questions. A big questions many missed was "what is the water cycle called?" many put transpiration cycle, while the real answer is the hydrologic cycle. That was the most missed question and the others were just human error rather than actually not knowing what the answer was. As for being prepared for the test I think our class will do well on the test.

Well today we didnt do much except watch mythbusters. they tested quite a few myths. they tested if a postage stamp was enough to critically unbalance a helicopter to the point that it would crash. so what the did was get a 1/7 scale model of helicopter and put seventh of a postage stamp on one of the blades. that didnt do anything so they then tested it on the real thing. again, it only affected the blades by 1 one thousandth of an inch. they also tested, or more or less found why dropping mentos in diet coke creates a geiser. the did research and found that it was due to four things: the CO2, the aspartame, the caffeine, and the nucleation that that pitted surface of the mentos causes.

Today in science class we tested several materials' pH's. Once we did that then we decided whether or not, by the pH if the material was acidic- acid contained, alkaline- a base, or lastly a neutral- having neither base, or acidic properties. Lastly, we took a quiz on the things we learned about each one of those definitions, and applied it to an actual material. What i learned from the things we did in science class today were, how to figure out whether a material is acidic, alkaline, or neutral.
