Geology- The Layers of the Earth

The four layers of the Earth.  Although most of our lessons are given individually (such as practical life, math and language) at times the children gather in a small group for a special presentation.  We had purchased a model of the Earth that splits in half and also had printed out our nomenclature cards for the children to match showing the different layers of the Earth. 
We discussed each layer: the inner core, the outer core, the mantle and the crust.
I then showed them a playdough Earth I had made the night before and proceeded to cut through to see the various layers. (Of course, this gave us a chance to discuss knife safety!)
We passed around the two halves and pointed out the different layers. 
After the presentation, many children chose to make their own Layers of the Earth booklet.
One child also pin-punched each layer and glued on to make a little diagram.
