This additional information may also help teachers to generate additional follow-up questions and extensions of this project.1.

Tell the class that today they will become an artifact.

What is the process of carbon dating, and can the results be believed?

Through the use of an interactive Web site, students will learn about C-14 and C-14 dating.

Students will be introduced to being science/math detectives by trying to figure out the relationship of organisms using graphs.

Students then are introduced to the controversy around the Shroud of Turin, which has been carbon dated.

Thus it can be very dangerous when there is an explosion—or in the case of Fukushima, an earthquake—at a nuclear plant, and some of the radioactive atoms escape into the surrounding air, water or soil, causing contamination.

Students will be able to: As a result of activities in grades 5-8, all students should develop understanding of science as a human endeavor, the nature of science, the history of science.

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.

Games with manipulative or computer simulations should help them in getting the idea of how a constant proportional rate of decay is consistent with declining measures that only gradually approach zero.

Remember carbon-14 dating cannot be used to date most fossils.

For more information on the restrictions on carbon-14 use in fossil dating see the carbon-14 background information page. Explain that each student will represent one carbon-14 atom in the artifact.
