In science class we finished a lab a couple of weeks ago. The lab that we did was the onion lab. In the onion lab. We used compound microscopes to examine the peel of an onion then we used iodine drops which turned them yellow. We had to draw pictures of the onion cells when they did not have iodine drops then when they did have iodine drops. Most of us saw the cell nucleus then we had the draw what we saw. After that we had to answer questions. I had good practice on my microscope skills and learned how to identify cells.
