Edible Model Earth

Continuing our geology unit study, we built an edible model Earth today.

If you want to replicate this, you will need:

a maraschino cherry
2 cups of crisp rice cereal
1 T butter
13 marshmallows
8 Oreo cookies (crushed into crumbs)
and peanut butter

Also soap for your hands. Lots and lots of soap.

The cherry gets stuffed into one marshmallow. That's the solid core inside the molten core.

Then, you make Rice Krispy Treats (melt the butter on the stove, add the marshmallows, stir until melted. Remove from heat, stir in cereal. let cool five minutes.

You take your rice treat mix and you mold it into a ball around your core. Try to make it as even and round as possible.

Next, smear peanut butter all over the outside. This is the MOHO layer. You will be dirty now.

Finally, roll your Earth in the cookie crumb crust, and you are done. If you carefully slice it in half, hopefully you can see all the layers nicely.

We were able to see all the layers, although our core didn't end up dead center. It was a tasty project.

We are loving this Intellego unit study on Geology!
