Radiometric dating activity answers
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.
Once all groups finish, each group records their info on the class decay table (on the board) and we calculate the averages of the class. Isotope Concepts: Students should begin to see the pattern that each time they dump out their M&Ms, about half become stable.
Students begin by pouring the 100 M&Ms on the table, and set aside the "stable" isotopes (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.The module is an integrated unit which addresses the following National Science Education Standards: *Science as Inquiry: Students develop the abilities necessary to do scientific inquiry identify questions, design and conduct scientific investigations, use appropriate tools and technologies to gather, analyze and interpret data, think critically and logically to make the relationships between evidence and explanations, communicate results, and use mathematics in all aspects of scientific inquiry.*Life Science: Fossils indicate that many organisms that lived long ago are extinct.
