Science 9/26

We had another exciting week in science. We continued our work with the charictaristics of life. We classified things into living and nonliving. Then we relized that those two catagories were not enough. We added two more catagories, dead and dormant. Then we noticed that we had trouble catagorizing things still such as an apple. For homework, we were assigned to think and write about why it is difficult to catagorize as a class. I wrote that because people are sometimes not as open minded or acceptive of ideas. It all depends on how creative you are.

We were told later in the week that we are going to do research to help Truman Middle School. The students there seem to be getting a disease, and are absent all the time. We looked at their website for info on the outbreak. Their attendance sheets gave us a good amount of info. Mr. Finley told us to make hypothesis about the disease. One that I noticed was that on May 22 something changed such as climate to cause more students to recive the illness. Tothether as a class we discused or hypthesises, that caused us to reach a dillema.

What is the difference between a prediction and a hypothesis? That was the problem. Mr. Finley helped us understand the difference. Hypothesises are testable questions based on fact. A prediction can only be made after a hypothesis is tested. A prediction is based off of the test results and can never be wrong. Only a hypothesis can be wrong.

The best part of the week was when Mr. Finley proved me wrong . I said metal can't burn. To prove me wrong he lit a piece of magnisium on fire. Coolest thing EVER.
