Radioactive dating worksheet
The amount of each type of bead for each bag is found in the directions on the website. Each team shares their data from the activity worksheets.
Assessment: Monitor students' work to check that they are carrying out procedures carefully, making observations, and recording data accurately. Discuss with the class as a whole the student responses to the end of the activity questions from the "Engagement" and "Exploration" sections of the learning cycle.
In this video I walk you through using the simulation.
As the students work on the simulation they are visualizing how stability and change in natural or designed systems can be constructed by examining the changes over time (CCC Stability and Change), as well as analyzing and interpreting data (SP4).
This lesson is designed to help students understand the concepts of radioactive dating to help determine the approximate age of fossils and rocks.
Students may confuse this random change of events with the non-random decay of radioactive isotopes.
Stress the fact radioactive decay is not random and is highly predictable based upon past empirical data.
