While the moment in time at which a particular nucleus decays is random, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques.

After one half-life has elapsed, one half of the atoms of the substance in question will have decayed.

We have chosen to focus on hominid evolution because (1) it is one of the most controversial and misunderstood topics in science today; (2) the hominid fossil record has recently become particularly rich, providing a framework for constructing phylogenies of human evolution; (3) skulls are small and transportable (vs whale bones), ideal for hands-on observations and measurements (currently at least 92 measurements are used in fossil skull interpretations, see Cameron and Groves We have found that students are fascinated by the opportunity to handle life-size fossil replicas and to find out the stories that can emerge from them.

Students gain an understanding of macroevolution (evolution occurring through deep time) vs microevolution, as radiometric dating of observed skulls reveals the magnitude of geologic time.

any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product.

Throughout their learning process, students develop into budding paleoanthropologists during which they create questions, generate evidence, develop scientific explanations, and share their interpretations of the story of our hominid past.

The amount of the isotope in the object is compared to the amount of the isotope's decay products.

The object's approximate age can then be figured out using the known rate of decay of the isotope.

They are then able to use this knowledge to construct similar inferences for extinct fossil hominids.

Using radiometric dating data, the students develop possible phylogenetic pathways for hominid evolution.

Mikhail Marov of the Vernadsky Institute of Geochemistry and Analytical Chemistry said scientists had determined the meteorite's age by observing the amount of radioactive isotopes and their decay byproducts, a technique called of a granodiorite at the Cuttaburra A prospect indicates that this mineralised system may be Middle Silurian in age and thus indicating that the host rocks are older than those hosting the Cobar-type deposits.
