Earth... is it like an onion?

So I just got done watching Shrek (the first one), and he talked about having many layers and then compared himself to an onion. This week for my lesson we discussed how the Earth has layers.

My lesson was great. The students really enjoyed it, and they seemed to learn the names of the layers. At the same time though it could have been that they just remembered the names because they wanted to eat their food. Either way, when they left my room they could identify the layers of the Earth.

I was not able to go to school the next day, and so I could not ask them what they remembered. However, I plan on asking them on Monday. This will be the true test. Then I will know if they information had truely sunk in.

Below are pictures of my students having fun learning about the layers.
