Social chat sex - Radioactive dating lesson
They should also understand that the atoms of any element are alike but are different from atoms of other elements.
Although students could work through the simulation individually, I prefer partnerwork to foster discussion among students, encouraging scientific discourse (SP7).
In this video I walk you through using the simulation.
So, we rely on radiometric dating to calculate their ages.
Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
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). To close this lesson I ask that students write, on Edmodo, what was the most interesting thing they learned in today's lesson.
