We have been carrying out more ice experiments today.  We have already found out that hot water melts ice and that a coat can act like an insulator.  Today we were trying to find out whether sand, salt or sugar would make the ice melt more quickly.  Lots of us thought that sand would melt the ice because ‘you get sand on beaches and beaches are hot places.’ 🙂

We found out that the salt made the ice melt the quickest.  We could see the ice cube with salt on it getting smaller and that the ice was turning into water.  We spoke about what the  road gritters might be spreading and why.  We found out that the sand was the slowest material to melt the ice.
