Carbon dating half life worksheet
As far as mastery of content, this activity is done in our rocks and minerals unit.
Students should have some prior knowledge of rocks and how they are dated. Materials Needed: -100 M&Ms (per group) -Notebook -Piece of Paper -Plastic Container with a Lid Lesson should be introduced by reviewing the 2 broad ways scientists age rocks (relative dating and radioactive dating).
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).
Daughter isotopes are represented by the M side down (stable).
Students begin by pouring the 100 M&Ms on the table, and set aside the "stable" isotopes (M side down).
They then gather the radioactive, or M side up M&Ms, put them back in the container, and then pour them out again. and continue this process until all M&Ms are stable, or M side down.
Equipment that is necessary is M&Ms– a lot because each group needs to begin with 100, and a container with a cover for each group.
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.
