Your skin is more than just natural packaging for your body – it is a large organ and contains things like nerve cells, sweat glands and small blood vessels. But how large is the surface of your skin? How can you measure how large your skin surface is?
How large is the surface of your skin?
You will need
- A second person to work with you
- 1 roll of toilet paper
- Masking tape
- Measuring tape or meter stick
Let’s get started!
1. Stand on one leg
One child stands with their left foot on the end of the toilet paper.
The second child carefully wraps the paper around up to the first child’s hip and down their right leg. The paper should not overlap!
2. Wrap above the waist and down one arm
Start wrapping again over the trousers (stick the end down first) and up the chest.
Then wrap the toilet paper around one shoulder, down one arm and to the hand.
3. Wrap the other arm and then the head
Now wrap the other arm up from the hand to the shoulder. Wrap around the shoulder and neck, then finally around the head. And you’re done! Now you can carefully unwind the paper again.
4. Mark out a square meter
Use masking tape to mark out a 1x1-meter square on the floor. Neatly fill in the square with the toilet paper. If the square is completely filled but you still have some paper left, put a second layer on top of the first until all the paper is laid out.
How many squares could you fill? That number is the approximate size of the surface of your skin.
