Carbon dating and video
Here is a site that would be a great out side reading material for further exploration of the topic, carbon dating. In class we would explain how it works, but if a student would like to know more about how it works, this link give a nice explanation and a video to supplement. On the site there are explanations to how C14 is naturally occurring and this is why we can use if for dating living objects. There are diagrams and even example math problems for students to see how half life is calculated.
