In this series of lessons students learn the basic principles used to determine the age of rocks and fossils by using half-life in radioactive decay and stratigraphy.Author/Source:
McKinney, Frank Grade level:
13-16 Time:
One to two class periods. Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - Radiometric dating can often be used to determine the age of rock layers and, hence, the fossils embedded in them.
- Scientists test their ideas using multiple lines of evidence.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
