Today’s objective was to compare the process of radioactive dating to the process of relative dating. We started the lesson with page 1 of the relative warm up. Then we worked on finishing your Fossils Application BCR (page 4). Then you worked on completing the determining Geologic Age: Relative Dating assignment. We then discussed the concept of half-life and how radioactive materials have a half-life and that this rate of decay can be used to determine the age of rock samples. We then looked at 100 Greatest Discoveries: Radioactive Dating. We will investigate this and other methods of absolute dating on Tuesday.
