This morning Nathan brought some rock salt to school. He asked if we could do an experiment with the salt. At circle time we had a discussion about what rock salt is used for. Many friends knew that rock salt is used on the roads and sidewalks to help make the ice less slippery. We decided to try an experiment. We had two bowls with ice, one with the salt and one with just ice.
The children checked the bowls and discovered that the in bowl with the salt (orange bowl), the ice melted faster. At home children could try the same experiement with table salt and see if they will get the same results.
