Investigating three types of matter, using shaving cream.
The first activity's materials is:
- Shaving cream
- 10 cents
- Magnifying glass
- Paper towel
Procedure:
- Place the folded paper towel on the table.
- Place a 10 cents coin on the middle of the paper towel just to ready it for later.
- Spray shaving foam on each end of the paper towel.
- Put the 10 cents coin on top of one end you sprayed shaving cream on.
- Observe it, is it sinking or sliding.
- Take a magnifying glass and look closely to the coin to see if it is actually sinking.
- Put a bit of the one on the other end on your index finger and start rubbing it with your thumb, what do you notice?
- Have a bit of fun with the other side and look at the coin, did it sink, if yes, you have found out it is a liquid.
Exciting, I will make sure I come with the camera next time.
