Radioactive dating lab
Once this is done, students have some post questions they are given that they should record in their science notebook.
Adapted from: For Special Ed and ELL kids, you could give them a template of the data table/graph.
This activity would also be easy to adapt when talking about half-lives within a chemistry course. Also, review what a half-life is (info given the day prior during lecture/ notes/ reading).
New information needed to be introduced with parent and daughter isotopes.
Daughter isotopes are represented by the M side down (stable).
Students should have the skill to set up a data table and a graph, however, if you want to use this activity with students that have not, you can provide them a template with that information.
Correctly estimate the age of the various virtual objects (skulls, rocks, etc.) using the principles of radiometric dating.
The activity is designed as an in-class competition between lab groups.
Popcorn popping is a great analogy for the spontaneity of radioactive decay.
It is impossible to predict which kernel will pop first.
