Then students will analyze an article written about the C-14 dating of the Shroud of Turin and draw conclusions.Although the results are definitive, they can be used to support either point of view.This lesson can be used as an introduction to radioactivity.Students should have familiarity with the scientific notation and the units milli, micro, and nano.However, once the organism dies, the amount of carbon-14 steadily decreases.By measuring the amount of carbon-14 left in the organism, it's possible to work out how old it is.Students will be introduced to being science/math detectives by trying to figure out the relationship of organisms using graphs.
There are a variety of websites used to teach and reinforce how to identify exponential growth or decay and how to solve problems relating to growth and decay.
You’ll also see how you can tell when a fossilized animal died by comparing the amount of carbon-14 that would have been in a living creature to the amount that’s left in the fossil. In this lesson plan, which is adaptable for grades K-12, students use Brain POP and/or Brain POP Jr.
resources to learn about planning projects when they create a science fair exhibit.
So, objects older than that do not contain enough of the isotope to be dated.
Conversely, the method doesn't work on objects that are too young.
