Haley, a student at ISB in Bangkok, where Allanah visited last Christmas, is just learning about blogs. She blogged about a science experiment she did and we thought we would do the same experiment here to see if the results were the same.
Today we did an experiment about coins. What we did was we cut some paper cups. We did a small one, a medium one and a large one.
We got a tote tray and put water in it then we got the cut paper cups and we got a bag of $2 coins and put them in the paper cups one at a time.
We put money into the cups that we had in the water. We had four different sized cups. The baby sized cup only took two coins to make it sink. The mummy sized cup only took two coins and the daddy sized cup took five coins. It was hard to put the coins in the middle so it was even.
We decided that the the taller cup held more air and that's why it was able to hold more coins. The pressure of the air underneath it helped to hold it up as well.
