This resource turns uncertainty in dating into a complete, ready to use review for Grade 9-12 earth science, covering the same idea from three different angles.

Students will answer questions such as "What can contribute to discrepancies between different dating methods?", "How does the conservation of isotopes contribute to dating uncertainty?", and "How can the presence of daughter isotopes affect dating accuracy?"
