Aim:
Finding a clear picture of onion cells?
Hypothesis:
The magnification I think we’ll be able to the onion cells is 40.
Equipment:
1 Onion
A Slide
A Cover Slip
Tweezers
A Blue Stain
Method:
Firstly, we peeled a thin layer of onion with the tweezers. We put the thin onion
layer on top of the slide Mrs Stone gave us, we put 2 drops of saline on top of onion to smooth it down. Next, we put 2-3 drops of blue stain on the slide. Mrs Stone gave us a cover slip to put on top of the onion/slide to cover it and then it was ready!

Observation:
For my point of view, It looked like wings but specific types of wings. It looked like
insect wings or fly wings. There’s lines everywhere that connect with each other
and little dots in between some of those gapes.
