We began the digestive system today, with the mouth. The boys added the taste buds and the face to our skeletons. Then they made a large model of the mouth for their notebooks. These show where on the tongue are the taste buds that specialize in certain flavors. They then could match different foods with specific flavors to the appropiate areas on the tongue.
Lips are the cover to the book. Sam and Alex will label the different types of teeth.
