    Relative and absolute dating lesson plan

    This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.

    The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.

    These radioactive isotopes are parent isotopes, which decay slowly to daughter isotopes, changing the rock’s isotopic character.

    The rate at which the isotopes decay is in effect our "geological clock".

    The Geological Timescale divides the Earth’s history into several periods of differing lengths of time.

    There are different ways that scientists can measure geological time.

    ESC.512 (Radioactive Decay as a Measure of Age - Earth Science) SCI. ESC.507 (Determining Relative Ages - Earth Science) SCI.

    This lesson introduces absolute dating and a few ways in which scientists accomplish it.

    The majority of the lesson focuses on radiometric dating, including an activity where students date their own "rocks and fossils".

    Then in Phase 2 of the project, the teacher will provide the students with plastic bins each representing a different stratum of the archaeological site.

    Using the absolute dating principles provided in Phase 1 of the lesson, students will make decisions of which artifacts to send to a lab for absolute dating.
