Freezing water

This was a wonderful idea, (stolen from Sid the Science Kid) poorly executed. This is definitely one of those activities where YOU can learn from my mistakes. Here's what I did....

The children and I put a bunch of fruit (i.e. grapes and strawberries) in a large Tupperware, filled it with water, covered it, and placed it in the freezer. We talked about what we thought would happen to the water and fruit. Some of the kids said they would turn into popsicles. I thought that was cute. :) The following class, I took the container out of the fridge and dumped the, now, big block of ice into a large bin. Then, the children felt the ice, and gave me ideas of how we could get to the fruit inside. I got ideas like: put it in the pantry, put it in the closet, melt it with cold water, melt it with hot water, etc.

Good so far, right? Here's where things start to fall apart.

We decide to melt it with hot water. So I gave each child a cup of water to pour over top of the ice, and I had a large pitcher. We counted one... two.. three.. and poured. Oops! The ice melted, but not enough to release any fruit. I had to go back to the sink (all the way in the kitchen) about 5 times. Meanwhile, the children were getting bored. Finally, all the ice melted, and we got the fruit. The grapes were wonderful, but the strawberries were mushy - I probably should have anticipated that. I also probably should have anticipated that getting a huge bin full of water out of the room might be difficult. I picked it up, one side gave way and - SPLASH - it went all over the floor. I raced to the sink to dump what was left, spilling much more water in the process, and proceeded to race around the room trying to clean up all of the water before someone fell. In the end, the kids really enjoyed it. I, on the other hand, did not.

However, I can learn from my own mistakes!!!

I did a few things differently with my other class. First of all, I did it outside - MUCH BETTER! Second, I was prepared with a couple pitchers. The strawberries still stunk though. Next time, I will only use grapes.
