I am going to tell you what I did yesterday (I didn't do any science today). Let me give you a little background before I begin my discussion of what occurred today.
I am almost finished with my first module of biology, well at least reading it. I mostly learned about the 4 criterion for life and classification. But yesterday at the end of the module I was introduced to the microscope. I have always wanted to work with a microscope and now I was finally able to. Here is the microscope.

Sorry the pictures are kind of fuzzy.
First in the experiment the book told me the parts of the microscope and how to work it. My older sister helped me with it because she has used microscopes a lot in college. Here is the setup

My first task was to put a drop of water on a slide and some threads.

I was then supposed to find the threads on the first magnification, the second, and the third. On the second magnification they looked soooo neat. I could see all the little strands that made up the thread.
Next I was supposed to collect some cells from inside my cheek and put them on a slide. Then I put some stain (dye) on the cells so I could see them.

This part of the experiment didn't work very well. Even after three tries I still couldn't find any cells. The slides were a little dirty though, so it was fun to look at dust and air bubbles.
Since the second portion of my experiment failed I decided to do my own little experiment. I pulled out a piece of my hair and cut it so it was short. I then placed it on the slide and took a look. Again the second magnification was the most interesting.
Well that concludes my post on that experiment, which by the way was Exp. 1.2. I hope you enjoyed this and that you will come back for more.
I am considering making this an interactive thing where you can post about what you did in science that day, too. It wouldn't have to be biology, just any course would do. BUT I will only do if enough people leave me a comment and say that they would like to do it. |
