Activity: Radioactive Dating: The Demise of Frosty
In this activity students will investigate the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point and then pool the data to make a graph that simulates halflife. Students will be introduced to solving mathematical problems that involve halflife.

History, Model of the Atom, Atomic Structure, Radiation, Half Lives, Subatomic Particles, Radioactive Isotopes  High School, Middle School
Activity: Marie Curie Video Questions
In this activity, students will watch a short video and learn about Marie Curie, her Nobel Prizes, radiation experiments, and discovery of new elements.

Half Lives, Radioactive Isotopes  High School
Activity: Using Dice to Explore Radioactive Decay
In this activity, students will use dice to simulate the radioactive “decay” of samples of two different elements with two different halflives. At the end of the simulation, all the groups will pool their data (by round) and then the class results will be graphed. The graphs will be analyzed to illustrate the process of radioactive decay and to determine the halflife of each element in the fictitious time units of “rounds”.

Radiation, Half Lives, Radioactive Isotopes  High School
Simulation: HalfLife Investigation
In this simulation, students will have the opportunity to investigate the decay of two samples of unstable atoms. Students will interact with the simulation in order to decay the unstable samples resulting in a visual and graphical interpretation of halflife.

Video: Marie Curie Video
This video tells the story about Marie Curie, including her Nobel Prizes, radiation experiments, and discovery of new elements. Irene Curie is also mentioned.

Half Lives  High School
Lab: Twizzler HalfLife
In this lab, students will better understand the concept of halflives.

Half Lives  High School
Lab: HalfLife
In this lab, students visualize the random nature of atomic decay (or first order chemical reactions) and also helps them realize the important difference between macroscale and microscale phenomena.
