radiometric dating activity answers-34

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 will only re shake the radioactive M&Ms each time. Once they are finished with their 8 runs, they will record their data on the class data table (which can be on the board).

Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives.

Once this is done, students have some post questions they are given that they should record in their science notebook.

Students begin by pouring the 100 M&Ms on the table, and set aside the "stable" isotopes (M side down).
