Following on from our frosty morning observations we decided to become scientists to investigate the quickest method to dissolve an ice cube. We brainstormed some ideas and came up with a list of things to investigate:
Set it in the sun
Put it on the radiator
Put it in salt
Put it in warm water
Put it in cold water
Put it in sugar
Put it in sand
The children helped to set up the investigation, finding the materials and labelling our work. We predicted that the ice cube would melt quickest in the sun. Observing the ice cubes we were surprised to find that the warm water dissolved the ice cube quickest. Given time all ice cubes melted.
Our conclusion was that warm water would be the quickest method of dissolving ice on your car windscreen!!
