DNA - Proteins

Task Description -

Whaea Kelly hasn't been coming to school for the past few days since she is sick, but today we had Mrs Ilaoa. Our little project we had to do was doing some research about DNA. I found proteins interesting so I decided to pick that as my subject. We had to make a poster and share it some of the students in our class. This is some of the interesting things I found out about Proteins. I hope you learnt something new from my research.

Experiment With Onion Cells

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.
