Dating rocks using radioactive decay
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.During each trial, students record the number of radioactive parent isotopes and record this in a data table.Many secular scientists use it to dismantle the faith of Christians and cause them to accept uniformitarian assumptions that, in addition to being scientifically erroneous, demand a figurative and distorted interpretation of Genesis.Being knowledgeable about such a widespread dating method is essential for Christians to address opposing arguments and critics. Natural radioactivity was discovered in 1896 by the French physicist Henri Becquerel.They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.— David Gross at 23rd Solvay Conference in December 2005 Radioactive dating is a key concept in determining the age of the earth.
A lot of the students said because they shook the containers differently... I also have students wash their hands before the activity, because of course after, the students eat the M&Ms. Radioactive decay and half-lives can be a very difficult concept for our 8th graders to grasp.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.Before we delve into radioactive decay and its use in dating rocks, let’s review some essential nuclear physics concepts.Each atom is made up of protons and neutrons concentrated in the atom’s center—its nucleus—around which electrons orbit.
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).
