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.

They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.Even if it happens to survive hundreds of half-lives, it still has a 50 percent chance of surviving through one more.Therefore, the decay of a nucleus is like random coin flipping.Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.

Therefore, the number of radioactive nuclei decreases from A more precise definition of half-life is that each nucleus has a 50 percent chance of surviving for a time equal to one half-life.
