Even though melting old broken crayons into "new", swirly, multicolored crayons has been done (and is almost cliche), you can't deny that kids love it! (which is why it's been done so much!)
Last time I had the "little" kids for art class, they found some crayons I had made with another girl a couple summers ago. The kids were doing some texture rubbings during free-draw time and found that the "muffin pan" crayons worked better since they were flat. When they asked about where the flat crayons came from, I told them about making them and said that could be the project for their next class, and they could make their own.
It was a pretty laid-back class today. Most of it was the kids peeling the paper off old, broken crayons and trying to break them into smaller pieces. I brought out a knife and cutting board so I could help cut them into even smaller pieces.
3 kids...3 rows of four...so each kid got to make 4 crayons. I suppose I could have taught a bit of a quick, simple math lesson here, but these kids are a bit small to be learning division.
The kids were SO excited to get them in the oven!
They were so cute! When I put the pan in the oven, they all sat right down in front of the window to watch the crayons melt!
We had a bit of a mini science lesson about solids and liquids. I explained that the crayons they cut up are solid, but then when heated they turn liquid, but then turn solid again when they cool.
I always like how they look on the bottom!
When I took the kids home, their older brothers saw the crayons and said they wanted to do this project too, so I guess I know what project I'll be doing again next week! Good thing I had broken crayons left over from today!
