Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
This experiment is best used by student working in pairs.
Grade Level: 5-12 grade Disciplinary Core Ideas (DCI) 3-5ETS1-2, MS-ESS1-4, HS-ESS1-6 Time for Teacher Preparation 40-60 minutes – To gather materials Activity Time: 40-60 minutes (1 Class Period) Materials: Objectives Students try to model radioactive decay by using the scientific thought process of creating a hypothesis, then testing it through inference.
The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.
Students are able to visualize and model what is meant by the half-life of a reaction.
