In this exploration, students build towers out of sugar cubes then explore what happens when they drip water on them.
Sugar is and example of a solid that breaks down into tiny pieces, and dissolves in water. When a solid dissolves, it seems to disappear. The dissolved solid is still there; we just can't see it.
Once students have seen sugar dissolve in water, they may be able to predict what will happen to a sugar cube when it gets wet.
These activities are part of Science World’s Big Science For Little Hands program. They were developed and tested with preschool and kindergarten educators. Some of the activities are done in stations.
