Today we did a science day since I am such a jerk and forgot about Art with C! I was telling L that we were going to do an Experiment. We were going to learn about ice. He smiled and thought this was cool, and then ran upstairs to get dressed. He asked me if he needed safety glasses and I said, probably not and he looked sad so I told him if he really wanted them he could get them. (His sunglasses lasted all about two minutes)
When water is a liquid it can take any shape of the container it is in. This is because the molecules can move around easily. (picture a ball pit) The molecules in a liquid can not be squashed nearer together or pulled farther apart, so liquids cannot be compressed or expanded by force. So we splashed a little and then filled the ice cube trays.
Ice is solid water. Can you splash it? Nope. In a solid like ice, the molecules can only move a little. So a solid stays in the same shape as it's container unless it has powerful force like crushing or twisting. The molecules are in a tight frame and are bonded together.
(I drew pictures do help them understand) My kids are in this need-to-know-why mode.
I asked them if they were ready for the Treasure hunt...
*Tips* Use distilled water for clear cubes. Minerals in regular tap will make the ice white.
This Science Fun can also be done outside, but it will melt faster.
