Radioactive dating problems worksheet

It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata.

This page contains links to guides to solving many of the the types of quantitative problems found in Chemistry 116.

Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.

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.

The Slides are to be shown at the front and then each item is shown in turn and the pupils use their graphs to calculate the age of each item from the percentage of carbon found in them. take longer than you think, but keeps them engaged and there're questions to be answered in their books also.

Understand how decay and half life work to enable radiometric dating.

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.

It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.

The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.

By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.
