Okay, I’m just going to say it: I am done with single digit temperatures! (And the windchills below zero.)
With the temperatures down so low, we decided to do a couple experiments with freezing water.
For our first one the kindergartner carefully measured out 1 cup of water into 3 separate containers. We placed one container in the refrigerator. (Sometimes the kids’ piddly amounts of water will freeze if they put their cup towards the back, so she wanted to test this out.) We put one in the freezer, and we stuck one container outside on the porch.
The I asked her which container she thought would freeze the fastest. Knowing how cold it is outside right now, with below zero windchill factors, she went with the one outside. Smart girl!
We checked our containers every 10-15 minutes.
After an hour, the water in the refrigerator was very cold, but not frozen.
Since the wind is really the factor right now, we did one more experiment.
I got out 2 old kitchen washcloths and got them wet. We put one in the freezer and hung one over the porch rail outside.
The kids were fascinated by how it held the shape of the rail it had been hanging on. The one in the freezer was not frozen yet.
By then this mommy was finished with going outside to check on our experiments; it was time for hot chocolate for everyone!
Have you done any ice experiments yet this winter?
