When I was single I went through a two year spate of dating commitment-phobes. Online dating has gone too far. Its time we gave our swiping fingers a rest. I enjoyed the rise and rise of Tinder. As much as anyone, but by using these dating apps, we are denying ourselves the most glorious part of the courtship process. Students will understand how scientists use half-lives to date the age of. Rocks. Skills: -critical thinking -data analysis -questioning -graphing and data collecting. Vocab Words: 1. Relative Dating 2. Radioactive Dating 3. Half-Lives 4. Isotope. Concepts: Students should begin to see the pattern that each time. They dump out . Students then should be able to see the connection of the MMs and radioactive. Elements in rocks, and how scientists can determine the age of rocks by looking at the amount of radioactive material in the rock. Context for Use.

Instructions: You should either share a copy of your graph with me through Google Docs or print off a copy and turn it in with. The answers to the lab analysis questions. Answer the following questions on a new shared Google Document. Or on a separate piece of paper. What procedural part of the experiment represented a half-life period. Of time in the experiment. Explain how scientists use radioactive dating to approximate a fossils age. Compare the numbers of protons and neutrons of 40K and 40Ar.
