Friday, October 29

This Friday we got our Unit 3 tests and our first quarter grades. We went over the test and then Mr. Henderson explained to us that the computer took off three of our worst webassign homework grades. There seemed to have been a problem, so he said that he would fix it once we went to the science computer lab. Once we got into the science computer lab we had to get with our qroups and exchange our information and work for the flight crash problems. Mr. Henderson said that if groups finished early they could start on the homework which was a Chemthink on chemical reactions. First we had to look at the tutorial to get the idea of the subject. Then we had to take a quiz on the material we just learned. You could only get 2 wrong. If you got three wrong you had to start over. mr. Henderson also told us a bout a work sheet on the back of the new packet that would be due with the Chemthink. The page has a front and a back side to it. An easy way to get it done would be, going through the tutorial and writing in the answers as you follow.

The basics of what we will be learning about in this unit is that the starting materials are called reactants, the materials that are created are called the products. You know that there has been a change when there is an arrow in between the two. This is just a little from the chemthink. There is a lot more to it than this. But I will let you figure that out for yourself.
