Homework 10/17/09

This past week in Science class we focused on demonstrating the uses of a microscope. My group tested a pot/chicken in a petri dish and pond water under a microscope. After that we resaerched and recorded our results. Before we could conduct our experiments we had to do a few quizes, like an oral quiz explaning how to use a microscope, and what the parts are and what they do. Then we wrote out procedures for them. We learned how to do experiments by doing mini lessons and having class discussions. It is very important to not do anything wrong when setting up or doing an experiment because then you knowledge is wrong because your results are not accurate, this is why we had to make sure to not contaminate the things that we were testing and to set up the slides carefully. We also talked about small organisms this week. We learned about them by studying a simulation that focuses in on tiny organisms such as Paramecium and tRNA. A stimulation is a picture that describes a transformation of a stage. It is important to know about these microscopic organisms because we are going to be experimenting with them, and they live around us so we should know a little bit about them at least.

Also This week we had to continue helping the nearby schools with finding out why there students have been getting sick. My group was going to test the pan for bacteria but the pan was gone, so the pond water was still there to test so we set up a slide and observed it, and we found multiple things.We found a dead organism and a living organism.
