Inquiry

Today in room 4 we were looking at cheek cells. We wanted to see what our cells would look
like under the microscope.

Hypothesis

We will see some of the organelle in our cheek cell

Equipment

Lolly pop stick

Slide

Sodium Chloride

Methylene Blue (stain)

Method

First we put the lolly pop stick inside of our mouth and rubbed our cheek.

Then we wiped the lolly pop stick on the slide

Next we added a drop of sodium chloride on top of the slide

Finally we added a drop of methylene blue to stain the water blue. 

This meant that our slides were ready to go under the microscope.

Why did we need to dye the liquid slide blue? so the side of the cheek cell you can see better
