New York State Standards in Science - Intermediate Students will use mathematical analysis, scientific inquiry, and engineering design, as appropriate, to pose questions, seek answers, and develop solutions.
(Mathematical Analysis and Scientific Inquiry) Students will apply the knowledge and thinking skills of mathematics, science, and technology to address real-life problems and make informed decisions.
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.
By about ten half-lives, or 58,000 years, the amount of carbon-14 left in the fossil is very little- about 1/1000 of the original number of carbon-14 atoms in the fossil.
So, using carbon dating for fossils older than 60,000 years is unreliable.
Carbon dating was developed by American scientist Willard Libby and his team at the University of Chicago.
Finally, students will do a radioactive simulation with pennies to reinforce the skills they learned about radioactive decay.
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.
This lesson can be used as an introduction to radioactivity.
