While this was a great activity to build fine motor skills, we wanted the children to have a purpose. We asked:
"melt it in the oven. us- (use a spatula) |
The next morning, we heated the rocks in the oven (350 for 10-12 minutes). We discovered that larger rocks need a little longer. The rocks became hot enough to melt the crayons, yet not hot enough to burn. (A few students didn't believe to rocks were hot, and touched them to see. A valuable life lesson!)
The results were gorgeous:
It's working because the rock is hot. -Ella It's wax so it melts. -Cameron Hu I can use two crayons at a time. You have to go carefully. -Kristien |
Look, now it's green! -Patrick |
I'm making a rainbow rock! -Ethan |
Hold it on for a while...now pull it off. See! You get lots. -Olivia to Kristien |
Hot lava! Look, it's starting to fall down. - Patrick |
"We're learning to be artists and scientists. We're watching it melt. The crayons are cold but the rock is hot. Like ice in the sun. It's like weird syrup on a rock pancake!"
