Science Experiments: Moving Molecules

We got our copy of Adventures with Atoms and Molecules in the mail last week, and I couldn’t wait to try it out.

I love that it has simple, straightforward experiments that demonstrate physical and chemical principles, without asking kids to figure out concepts that are far above their level of knowledge. There are plenty of science experiment books out there, and this is an important thing to remember when using any of them. At this age (we’re ramping up for 2nd grade), students need to observe, record, and learn from the experiments. These activities shouldn’t be “magic tricks” that are never explained, nor should they be unfathomable mysteries.

This morning we watched (groups of) molecules move and talked about the differences between how the molecules move in warm water, cool water, and ice:
