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. Basic understanding of how radiometric dating works is useful. This lesson is highly simplified, and the powerpoint describes everything the student will need to know for the activity.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 activity has students working as archaeologists.They will excavate a hypothetical archaeological site from their school yard, make observations, and write an interpretation of the history of the area based on the evidence they will excavate.
The majority of the lesson focuses on radiometric dating, including an activity where students date their own "rocks and fossils".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.Concept 3, PO 5: Distinguish between relative and absolute geologic dating techniques.| Teaching Weathering, Erosion, & Deposition | | Teaching the Metric System | Teaching the Water Cycle | Teaching Plate Tectonics | Teaching Earthquakes | Teaching Volcanoes | | Teaching Experimental Design | Contains over 200 pages of ready-to-run materials covering: Relative and Absolute Time, Sequencing Geologic Events, Geologic History Timelines, Geologic Eras, Fossils, Tree Cookies, and Radiactive Dating.The Packet contains: Objectives and strategies, detailed lesson plans & ideas, bellwork and journal suggestions, labs and worksheets with answers, tests & quizzes with answers, active learning suggestions including the Rules of the Game Foldable, and game suggestions you can run off on colored paper.
To facilitate the activity, the teacher will provide some introduction to absolute dating principles through the Half Life of M&M Worksheet.
