Today we had a science challenge. Some penguins had been frozen in ice and we had to set them free. There was salt, warm water and sugar to help us. We made predictions about what would happen. Lots of people thought the hot water would melt the ice the quickest because it is hotter than the ice. James thought it would be the salt as his dad uses salt when its icy to clear the drive.
We watched the ice with the different substances on it. The ice with salt on melted the quickest. It stayed on the egg and kept it melting when the hot water disappeared.
