Layers of the Earth

I am teaching "Layers of the Earth" in science right now. I found the CUTEST song on the internet. http://www.educationalrap.com/59/lay...the-earth.html

Even though some of it is over my 2nd graders, they still loved it. It definitely helped them remember the 4 layers 2nd graders need to know. So....throw your hands UP!

I know someone who makes an earth cake (three colored layers) out of ice cream for her class. Then rolls it in nuts. Yum!

We made an Earth today as well.

Crust= I gave each student a zip-loc bag and one whole graham cracker. We discussed how the crust was made of rocks and soil. They turned their cracker into crust by crumbling, smashing and beating.

Mantle= I put some extra crunchy peanut butter into a mixing bowl (I don't have any students with nut allergies this year). Students observed the "rocky" look. Mix in tons of powdered sugar to make stiff! Once stiff enough, I scooped some on each student's plate. They formed into the shape of Earth. Then they cut it in 1/2 with plastic knife and poked a small indention in each 1/2.

Outer Core= I gave each student a squirt of decorating icing (the gel icing would have been great but my store was out) for the liquid layer.

Inner Core= Students placed a red hot inside the "liquid layer". Appropriate since this is the hottest part of the Earth.
Put the halves together and drop into the plastic bag of crust to roll around ..... voila! Earth with all its layers.

Here's a worksheet I created to assess. Hope it will attach.

I really don't remember exactly how it went, but one teacher used a hard boiled egg to represent the layers of the earth. The kids loved it because then they could eat it!!!!

polarteach- I have racked my brain for an alternative. What about rice crispy treats cut into small squares? They are "rocky", kids could roll them into a ball shape, and they are sticky enough that the graham cracker crumbs might stick to the outside. Just a thought...???

Hard boil and egg. Have the kids tap it gently on their desks until it has cracks all over. Then have them push it together-gently-- and watch how it represents folding and bending of rocks, pull it apart and it is spreading plates, You will also see slipping and sliding plate movement. Kids think it is neat.
