Connor worked with Ed to test the expansion of various substances when frozen to two different temperatures. Helen played a supporting role. The highlight of the experiment for Connor was when I intentionally dropped an egg that had been cooled to 20 degrees to confirm that it wasn't frozen.
Many liquids freeze at 20 degrees.
Eggs, do not freeze at 20 degrees.
But that is OK, because seeing your clean-obsessed mom intentionally drop an egg on the floor is hilarious. Trust me on this one. It even made it into the final display board, which Connor was extremely proud to have created.
At the Science Fair, I had three very proud scientists. I was the jerk mom who ran in to see her child's project, spoke to the Principal briefly, and then dashed out - probably to go running, but I'm not entirely sure about that. I had something else to do, I know.
