Skittle Radiometric Decay Half-life Lab
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 th

Determination of acceleration due to gravity lab
Students will choose an object to drop from rest to measure the time of fall. After several trials, students will use kinematic equations to calculate the Earth's gravitational constant. This "economy style" lab uses few materials and is an excellent introduction to free fall. Students are asked to design their own experimental method rather than following recipe type instructions. A teacher's page is provided and includes hints, suggestions, possible sources of error and answers to the "motion
