Radioactive dating worksheet biloxi dating
Students may confuse this random change of events with the non-random decay of radioactive isotopes.Stress the fact radioactive decay is not random and is highly predictable based upon past empirical data.I tell the students that they will now become archaeologists as they play with the Ph ET simulation "Radioactive Dating Game".I ask the students to divide themselves into partners, and request that one partner to get a computer, while the second partner gets the record sheet they will use.
Assessment: Have students explain in their own words the concept of half-life in radioactive decay, demonstrate how the rate of radioactive decay and the buildup of the resulting decay product are used in radiometric dating of rocks, and compare and contrast individual statistical data results to the class average of various statistical data results to determine reliability and predictability of the two groups.
The M&Ms can be eaten by the students at the end of the activity.
Make sure to know any food related allergies of the students before handing them the candy.
During the discussion explain to students how this decay is at a set rate for a given element and that by measuring the percent rate of decay scientists can accurately predict the approximate age of a fossil or rock.
This is not to be confused with the statistical probability of the change in the population over time as demonstrated with an individual group's data during the M&Ms activity.
