In this project, you will simulate radiometric dating using different colored candies to represent isotopes. By measuring half-lives and decay rates, you'll estimate the age of a geological sample. This experiment demonstrates how scientists date rocks and fossils, helping us understand Earth's history.
If we simulate the decay of isotopes, then we can accurately estimate the age of a sample based on the remaining quantity of the isotopes.

Separate the colored candies into two distinct colors.
Count the total number of candies and record the data.
Set a timer for a predetermined time to represent a half-life.
After time is up, remove one color of candies to simulate decay.
Record the remaining candies.
Repeat the process for several half-lives.
Plot the data on graph paper to visualize decay.
Use the graph to estimate the age of the sample.
The data will show an exponential decay curve, allowing you to estimate the age of your sample based on the remaining isotopes.

Ensure candies are safe to eat, and supervise younger students while they handle food items.
Use visual aids like graphs to show results.
Incorporate a model that explains the concept of half-lives.
Include a timeline of Earth's geological history.
Prepare to answer questions on real-world applications.
It's a method used to date materials by measuring the decay of radioactive isotopes.
It helps understand the age of rocks and fossils, providing insight into Earth's history.
No, this is a simulation; real isotopes require specialized equipment and safety protocols.
