Tuesday 8.31.10

First, Mr. Paek talked about the microscope lab that we were going to be doing later on in the class and finishing on Wednesday. He also talked about the “quest”(quiz/test) we were going to have on THURSDAY about microscopes and making graphs.
Second we looked in out UP (unit packets) page 33 and it was about the microscopes (compound) were going to be using. Then, we were taught the do’s and dont’s of handling a microscope. Such as
1. Start with the lowest power (smallest lens) then work your way up to the strongest.
2.Mr. Paek talked about how the microscope lens and how the eye piece already magnifies whatever you’re looking at by 10 times. (pg 41 in packet)
3. And the different types of various knobs that moved the stage, focused on what you’re looking at, or made it more defined. And the knob that lets more light in to see your slide.
The class got into groups of 2-3 and started the lab, looking at a lot of different slides, such as; a wet mount slide with pond water, a wet mount slide also but with yeast culture, and another wet mount slide with a fish scale.
Taking out the microscope, and making the wet mount slide (that we learned how to by putting whatever you’re looking at on the slide and putting a drop of water on it, then putting a plastic cover over it) and then drawing a colored picture about what you saw, then answering questions that corresponded to what you just looked at.
When you were done with the mandatory slides to look at, turning to page 39 in your UP, and getting a dollar bill from either Mr.Paek of your own, you looked at the dollar bill with good ol’ George Washington’s facing you, then answering the questions on the page.
We didn’t have time to finish the lab, so that was all we got up to for today.
