Radioactive dating video
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).Daughter isotopes are represented by the M side down (stable).
Students will record the number of M&Ms that are still "radioactive" (M side up) in their data table after each run, and set aside the "stable" (M side down) M&Ms.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.
