Radioactive decay dating video datingolderwomen net

Carbon dating uses an unstable isotope of carbon to find the date of dead substances.

This isotope Carbon-14 has a half life of 5,700 years.

Although students could work through the simulation individually, I prefer partnerwork to foster discussion among students, encouraging scientific discourse (SP7).

In this video I walk you through using the simulation.

This is exactly how carbon dating works, but with dinosaurs instead of models.

This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.In a large collection of atoms, there is a definite time, called the half-life of the isotope, after which one-half of the total number of nuclei would have decayed.This time varies from few-millionths of a second to millions of years for different radioactive isotopes.I know can be hard to wrap your head around, so let's model it with a six-sided die. You can use Lego bricks, pennies, beans—anything you can easily count. Every time you roll a one, put that object into a separate pile.Count the remaining objects and repeat the process until half of them have decayed. It took a while, but we finally got pretty close to 40 tiles left.
