We started the class by making questions for the plant microscope experiment. Mr. Finley
introduced to us that we would be getting different samples for the microscope experiment. Then representatives from each table went outside to get a new sample of grass. Next we went over the procedure for making a slide. We remembered that we should only use ond drop of water and only a tiny piece of grass. While the people from each group were outside the others set up the microscope. We made a slide and looked at the piece of grass. We got ours perfect in focus from low power. We drew the picture of our grass next under low power. We say that the grass under low power had little dots on it and they looked like cells or water. Then we
set the microscope to high power and drew a picture of that in our notebook. Under high power the grass looked like it had dots too. The dots looked like they were dark on the outside and lighter on the inside. They looked like they were in a row. There was also a line in the middle of the grass. the dots were close to get her. After we drew our pictures we went on and answered questions about what we saw while Mr. finley called us up to see our grades. When the gr
oup finished the grass experiment we moved on to an onion experiment where we looked at a tiny piece of an onion and put iodine on it to make the cells darker when we put it under the microscope. The onion cells were in a line and linked together under low power. Also
under low power the onion cells were long and and looked thin. We didnt get to get to highpower with the onion but we finished the grass lab from yesterday. I think that class today
was very interesting and it was pretty interesting. The microscopes really help us see things that are very hard to see. Todays class was great and we got to see where some of the parts
of a cell can be located. Here are some pictures of what the grass and onion cells looked like from under the microscope.
