How carbon dating works for kids Dating your boss
Empty the graduated cylinders between classes if the volume is more than about 25 ml."Carbon-14 undergoes beta decay with a half-life of 5720 years.In this interactive, learn how radiocarbon dating works, what it takes to determine a date in the lab, and why it's challenging to pinpoint a date precisely.This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.
The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.
It is incorporated into the carbon cycle, so that all living things, including you, contain radioactive carbon-14.
Living things have about 15 disintegrations per minute per gram of carbon.
Write a letter to a friend explaining what radiocarbon dating is.
Be sure to include how radiocarbon dating works backwards to solve a puzzle.
To be able to do this lesson and understand the idea of half-life, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
