Activity 1.1 What am I made out of?
February 4, 2015
What did we do?
We took a piece of tape and put it on an elbow and removed it. After adding blue dye we made a slide and observed it under the proscope. We saw blue speckles. These are skin cells. There are thousands of these.

Why did we do it?
We did this to show that we are made of cells. How many different kinds of cells are there? |
Skin cells at 200 x on the Proscope

Activity 1.1 What am I made out of?
February 5, 2015 What did we do? We scraped the inside of our cheek with toothpick to get cheek cells. With the ProScope we saw little blue speckles with darker speckles mixed in. In the microscope photo they were bigger and more detailed. The shapes were all different, almost like watercolor paint. |

Activity 5.2 How does water get into the cell?
February 26, 2015
What did we do?
We peeled a layer of red onion skin and looked at it under a microscope. The cells were filled with water. Then we added salt water and observed the cells had shriveled
Why did we do it?
We were learning about osmosis. Water can pass in and out of the cell.
