We explain half-life qualitatively, mathematically, and graphically. We also look at how we use this principle to find the age of objects.
Segment 7D: Half-Life We explain half-life qualitatively, mathematically, and graphically. We also look at how we use this principle to find the age of objects.Premiere Date: August 1, 2018 | Runtime: 00:07:26
-Explore the nature of radioactive substances by understanding their half-life qualitatively and what that tells us about their stability.
-Understand how to graph the decay rate of a radioactive substance and relate this to the half-life of the substance.
-Calculate how much of a substance will remain after a certain number of half-lives have occurred.
-Investigate how half-life is used to find the age of objects.
carbon dating - a method of determining the age of substances that contain organic material by looking that the ratio of carbon-12 to carbon-14 they contain.
half-life - the time it takes for half of a radioactive substance to decay.
radioactive decay - the spontaneous emission of charged particles and/or energy from an atom.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
