This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. This is the first lesson in a unit of 4 lessons that integrates science, math, and computer science standards to teach the concept of half-lives and radioactive dating. Students will be able to explain what a half-life of a rock is. This tutorial will demonstrate a number of strategies teachers can impart to students to help them use context clues to determine the meaning of unfamiliar words within science texts.
The element carbon is an essential element in all living matter. This activity involves recording and graphing data as well as a short data analysis segment. Atoms may stick together in well-defined molecules or they could be packed together in large arrays. The teacher may also choose to assist in guiding the students through the process of graphing the recorded data by saying the following script: Adapted from:
Once this info is calculated, students create a graph comparing the class average of parent isotopes to the number of half-lives.
Overhead transparencies of: Larry Flammer, April,and successfully tested on classes of Earth Science students. Sample questions and correct answers below:. The teacher can engage students in an extension discussion with this question: Begin by having students read the article The Story of Carbon Dating. The Nobel Prize in Chemistry Presentation Speechgiven at the presentation of the Nobel Prize to professor Willard Libby for his use of carbon, highlights how the dating method works.
