Radioactive dating game worksheet
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
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).It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages. Rather, it's a way to determine the age of organic remains such as bone, teeth, and seeds by finding out how much carbon-14 is left in the remains. At the very least you'll find out what it's like to date a 9,000-year-old skeleton such as Kennewick Man's.Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.
Students begin by pouring the 100 M&Ms on the table, and set aside the "stable" isotopes (M side down).
