Pupils from 4th and 6th class have been investigating the effects of heat.
Here are the recordings of one of these students:
Last week I did an experiment about heat.
A thermal conductor is something that lets heat pass through it.
My investigation was to find out which material the best thermal conductor.
The materials I tested were:
The other equipment I needed was:
• 4 mugs
I predicted that metal would be the best thermal conductor.
This was correct because the butter and pasta melted on the knife the quickest.
I noticed that when the butter fell in the water it changed into liquid. I also noticed that the wool was the only material to absorb water.
A note from Ms. Ni Dhalaigh:
If you would like to carry out this investigation at home make sure you have an adult to help you with the hot water. Be very careful!
