Description
Did you know you can use Skittles candy to demonstrate absolute dating and radiometric decay! Buy a 1-4 lb bag at your local bulk warehouse store for savings.
This lab is a great way to show how isotopes decay by shaking a plate full of random skittles.
Students use Skittles to observe "Isotopes" decay over each half life. At the end of the lab (and only IF they have done all their work) they can enjoy their "daughter products".
Skittles were used because they are durable, hypoallergenic, and the gelatin S logo is only on one side.
They will practice graphing data and producing tables as well in this lab. Included in the zip file is an excel file sample for your students!
Please check with your students and admin before doing this lab. Check for any food allergies before bringing food into class.
