Radiometric dating mm lab

Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.This experiment is best used by student working in pairs.

It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.Plot the total results on a graph with number of candies on the vertical axis and trial number on the horizontal axis.Living things have about 15 disintegrations per minute per gram of carbon. This simulation is intended to help students use what they already know elementary probability to the concept of radioactive mac hookup to projector and how it can be used to determine the absolute age of an igneous rock.Radioactive materials contain some nuclei that are stable and other nuclei that are unstable.Not all of the atoms of a radioactive isotope (radioisotope) decay at the same time.If two nuclei have different masses, but the same atomic number, those nuclei are considered to be isotopes.

Isotopes have the same chemical properties, but different physical properties.

Each group of students presents its answer to one or two of the discussion questions.

This site enables the teacher to see who is having difficulty and who is not by looking at the speed of the student.

Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.

Seeing this connection will help students to understand how scientists can determine the age of a sample by looking at the amount of radioactive material in the sample.

Students must get the questions correct before proceeding to the next page.
