Radioactive dating for kids
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).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.
The geologist may have found some fossils in Sedimentary Rocks A and discovered that they are similar to fossils found in some other rocks in the region.They not only enjoyed this activity, but they really gained a better understanding of it as well.by Tas Walker A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.Once this is done, students have some post questions they are given that they should record in their science notebook.Adapted from: For Special Ed and ELL kids, you could give them a template of the data table/graph.
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.
