College Board Standards for College Success: Science ES.3 Earth’s History: Relative and Absolute dating.
Students understand that various dating methods — relative and absolute — have been used to determine the age of Earth. Between Earth Science and Other Disciplines: Evidence of Common Ancestry and Divergence (LS.1.1); Living Systems and the Physical Environment (LS.3.1); Nuclear Chemistry (C.1.6); Nuclear Interactions and the Conservation of Mass–Energy (P.2.3) Benchmarks: American Association for the Advancement of Science.
With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Hovind is confusing the carbon-14 "clock" with other radiometric "clocks." The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period.
Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement.
Then students take the class data and create a graph comparing the number of parent isotopes to the number of half-lives.
Once this is done, students have some post questions they are given that they should record in their science notebook.
Once all groups data is on the table, you can calculate the average for each run (1-8) and determine a class average.
