To demonstrate that the rates of decay of unstable nuclei can be measured, that the exact time that a certain nucleus will decay cannot be predicted, and that it takes a very large number of nuclei to find the rate of decay.

But unlike historythe study of written records such as government archives, personal correspondence, and business documentsmost of the information gathered in archaeology comes from the study of objects lying on or under the ground Archaeologists refer to the vast store of information about the human past as the archaeological record.
Correctly estimate the age of the various virtual objects (skulls, rocks, etc.) using the principles of radiometric dating.
The activity is designed as an in-class competition between lab groups.
Answer key available to classroom instructors with verifiable email addresses.
However, archaeology is distinct from paleontology and studies only past human life.
Archaeology also examines many of the same topics explored by historians.
The mathematics of inferring backwards from measurements to age is not appropriate for most students.
They need only know that such calculations are possible. 79.) In this lesson, students will be asked to simulate radioactive decay by pouring small candies, such as plain M&M's® or Skittles®, from a cup and counting which candies fall with their manufacturer's mark down or up.
To do this lesson and understand half-life and rates of radioactive decay, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
