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.As far as mastery of content, this activity is done in our rocks and minerals unit.

Skills: -critical thinking -data analysis -questioning -graphing and data collecting Vocab Words: 1. This activity can be adapted for older students, but is used in an 8th grade earth science classroom.Carbon is a very important chemical element, with a chemical symbol of C. Many of the substances that people use daily are organic compounds. Methane, Propane, and many other fuels are hydrocarbons.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).Carbon forms a very large number of organic compounds because it can form strong bonds with itself and with other elements.Because of the amounts of carbon living things have, all organic things are considered "carbon-based".The radioactive decay of carbon-14 may be invaluable for dating biological artefacts, but no one has ever been sure why it is so slow.Now, researchers in the US and Canada think it is because mesons — elementary particles that contribute indirectly to the decay — change their properties as they pass through a carbon-14 nucleus.Class size can vary, but activity should be done in groups of 2-3.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.
