Designing an investigation with hot water, graduated cups and plastic wrap, fifth graders are gathering evidence that the water must be in the air when it evaporates. Why? Because it ended up on the plastic wrap.
Our current thoughts....
1. Water must move. That's weird, because it's a non-living thing.
2. Our water was hot. Does this happen with cold water or room temperature water? Our lakes we built (or a real lake for that matter) are not hot. This gets us thinking...
