We will be spending the next week or two exploring the qualities of solids, liquids, and gases. We started this today by heading outdoors to melt ice in the sun. The kids worked in small groups to develop a question they wanted to explore. Some included:
Will ice melt faster on a metal surface or a concrete surface?
Will ice melt faster when surrounded by water or air?
Which of our shoes will make the ice melt faster? (Or, which holds heat more?)
Will the ice melt faster on concrete or asphalt?
Will ice melt faster in direct sun?
Everyone really enjoyed these mini-experiments. We found that some surfaces do, in fact, absorb heat more than others. Introducing heat to a solid to turn it into a liquid is called melting. As we all know, ice melts rather easily. Other solids require a much more intense heat source to melt - think rocks!
