Which material would be best to keep our ice lolly cold?
Due to the nice warm weather that we have been having we thought it was an important job to work out which material would keep our ice lolly the coldest. In small groups, we chose different materials and monitored how quickly each ice lolly melted. Most of the class thought that the cold water would keep the ice lolly the coldest because it is cold......they quickly found out that this was not the case!
