Friday Period 4
Today during class, we started off by having our microscope experts share their knowledge with us. Caroline, Claudia, Chloe, and I shared vocab and how to use the microscope properly. We told them everything from starting on the lowest magnification to what the different parts are and how to use them.

After the people presented, we talked about the order of multi cellular organisms. We looked back into our notes to to try to figure out the correct order again. Below is what we configured.

Multi Cellular Organisms

Organ System

Organs

Tissues

Cells

After reviewing this, Mr. Finley taugh us how to make a wet mount slide for our experiment for the day. Before he made the example, he said we would be studying our cheek cells under the microscope today. He told us that we are always loosing cells in our mouth when we eat of scratch our skin. Mr. Finley also told us that most of the thing that float in the air are dead cells. Next, Mr. Finley made the example He made it in the following order.

-He swabbed his cheek and put it on the slide

He dropped one drop of methionine

-Then he put on the cover slip.

- Finally he put it under the microscope to focus it and observe it.

When he was finished with the slide, it was our turn to make one. Unfortunately, because of time, class ended before we could really get into looking at our cells under the microscope. People also voted to do it again on Monday instead of trying to catch up. What a shame. Lucky for us, one group was able to focus it rally quickly so we could take a look. (see pic. above) This was a great learning experiment for us about how to use dry mount slides.

  1. The advanced group told us info like.....
    cover slip- clear piece of plastic used to cover your sample.
    slide- what the sample goes on
    dry slide- a slide with no liquids
    -start with low power then once you have an image switch it to high power and only change the fine adjustment.
