This week, the kids are learning about the earth's layers.
We touched on it briefly last year, and decided to
review it a bit.
After enjoying a book about the different layers, figuring out
how long each layer is, and discussing the
heat that melts rocks, the kids made their own
earth graphs.
Using their compasses, they traced out circles of varying sizes.
Discussing heat so hot that it could melt rock led
us to other discussions of things that could melt with
lots of heat. Snow, ice, chocolate, and crayons.
Thrilled by the idea that crayons melt, the kids
rifled through the crayon tin looking for broken crayons.
We peeled paper, broke them apart,
and placed them in muffin tins.
Setting the oven at 275, they watched for fifteen minutes
as their crayons melted.
The colors they chose were so pretty, and they loved the idea
that the mantle layer of earth is so hot that the rock melts.
After about an hour, our old crayons looked new again.
During all of our fun, I think the kids might have learned a thing
or two about the earth.
