This is a great way to either introduce an unit on the layers of the Earth or as a review. It covers vocabulary over Earth's layers and it also has comprehensive questions students will answer by using the information gathered on the scavenger hunt. I find this is great way to cover a lot of information that allows the student to get up, move around and work with others in a cooperative manner. On top of this the students really enjoy learnng voacabulary in a non-traditional dictionary and pencil manner.
