Today Room 4 were looking at cheek cells. We wanted to see how these cells looked compared to other cells. First we watched a video about how to see a cell under the microscope. The equipment we need was a Lolly Pop Stick, a slide, Sodium Chloride, and Methylene Blue (which is stain).
First, one of us took the Lolly Pop Stick, and gently rubbed it against our mouth, which caused all the dead cells to come of. Then we rubbed the Lolly Pop Stick against the slide, which caused all the cells to go on it. After we threw the stick away, we put a drop of Sodium Chloride on, and a drop of Methylene Blue on. Then we waited for it to dry.
After we let it dry, we took the microscope and put the slide under it. Then we could see the cells. They were hard to see at first, but after we magnified it, we could see all the cells. I hope we do more work on these cells, and hopefully, we can do work on other cells.
