Radioactive carbon dating demonstration
Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.
This experiment is best used by student working in pairs.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.
Carbon-14 is radioactive and undergoes radioactive decay.An example of isotopes is carbon, which has three main isotopes, carbon-12, carbon-13 and carbon-14.All three isotopes have the same atomic number of 6, but have different numbers of neutrons.You’ll also see how you can tell when a fossilized animal died by comparing the amount of carbon-14 that would have been in a living creature to the amount that’s left in the fossil. In this lesson plan, which is adaptable for grades K-12, students use Brain POP and/or Brain POP Jr.resources to learn about planning projects when they create a science fair exhibit.
