Determining the Age of Rocks and Fossils, University of California, Berkeley. This 9-12-grade activity introduces students to age dating with exercises using relative and absolute dating. Links to various activities and lesson plans concerning relative and absolute dating. Content information about absolute and relative dating methods used by the U. For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic.Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed.Strand 1: Inquiry Process Concept 2, PO 5: Record observations, notes, sketches, questions, and ideas using tools such as journals, charts, graphs, and computers.Concept 3, PO 1: Interpret data that show a variety of possible relationships Concept 4, PO 2: Produce graphs that communicate data Concept 4, PO 3: Communicate results clearly and logically Concept 4, PO 4: Support conclusions with logical scientific arguments Strand 6: Earth and Space Science Concept 3, PO 4: Interpret a geologic time scale.Correlation can involve matching an undated rock with a dated one at another location.

Throughout the history of life, different organisms have appeared, flourished and become extinct.

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.

This 5-12-grade activity introduces students to the idea of sequencing information in overlapping data sets and the Principle of Superposition, which is a core concept in relative dating. Offers history of age dating, stratigraphic principles, rock correlation, fossil correlations, radiometric dating, and the geologic time scale. Short discussion of radioactive dating and stratigraphic principles.

Radiometric Dating and the Geologic Time Scale, The Talk Origins Archive. Provides brief overview of (1) relative dating and stratigraphic methods, (2) absolute dating and radiometric dating, including a table with parent to daughter isotopes and half lives of those isotopes commonly used in radiometric dating, (3) paleomagnetics and (4) geologic time. Includes tables of common radioactive parent isotopes and their stable daughter products, and half lives of common radioactive isotopes.

This matching process is called correlation, which has been an important process in constructing geological timescales.
