Renewable versus Non-renewable resources

As students wrestle with their understanding of these two terms, questions are common!  There were several a-ha moments in class today.  One student used the example of a young tree being renewable, if sound practices are used to plant more trees, while a 500-year-old Redwood tree is not renewable.  This link was sent to students to help deepen their understanding.
