Layers of the Earth

The youngest group of students has been learning about the layers of the earth.  We started off our unit by reading parts of Gail Gibbon's bookPlanet Earth/Inside Out and How to Dig a Hole to the Otherside of the World by Faith McNulty.  As we learned about the many layers, we made small models out of clay and are in the process of making LARGE cardboard models that will include the many layers as well as what we can find on the crust of our earth.  As we finish up our earth models, we have gone on to read and learn more about how magma comes up from one of the layers and out of volcanoes!
