Once in a Million Years: Teaching Geologic Time This article outlines pedagogical approaches to teaching geologic time and describes common student preconceptions and misconceptions.

Thus, it is no surprise that geologic time is difficult for students of all ages to conceptualize.Additionally, knowledge of the nature of science in general, and geologic science in particular, is needed. The first is to complement teacher content knowledge and its relationship to the nature of geologic science.Geology is not a laboratory-based science lending itself to traditional notions of controlled experiments; rather it is a historical science requiring different methods.Relative time can be thought of as the subdivisions of rock found in the earth’s stratigraphy and absolute time as the measurements taken of rock types to determine the actual time that has expired.Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or geochronologic time scale.The Science Educator’s Guide to Selecting High-Quality Instructional Materials This guide presents a method for judging the quality of K-12 teaching materials, both in print and online.It is based on AAAS Project 2061’s curriculum-materials analysis procedure which was developed over several years with funding from the National Science Foundation and in consultation with K–12 teachers, materials developers, scientists, teacher educators, and cognitive researchers nationwide.Geologic Time is captured in at least two different areas. The other is under the Physical Setting--Changes in the Earth's Surface which includes rates of change.An image of the middle grades (6-8) only part of the Changes in the Earth's Surface map appears below.Fossils, Rocks, and Time This online book, published by the U. Geological Survey, discusses the use of fossils in determining the age of rocks.The book covers how to place events in correct temporal order, a description of the geologic time scale, the use of fossils to indicate rock ages, the law of fossil succession, index fossils, and radioactive dating.


  1. Relative Dating Evidence from. Then you determine the age of the object relative to the other objects or events in. Microsoft PowerPoint - RelativeDating.

  2. Chapter 8 Geologic Time. Fig. 8.13. OBJECTIVES • Define, compare, and contrast relative and absolute age dating. PowerPoint Presentation Author

  3. The purpose of this exercise is to introduce students to how simple relative age correlation. Relative Age Correlation Exercise PowerPoint. Relative Age Dating.

  4. Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy layers.

  5. Concepts on the relative age dating worksheet will help them to determine which layers came first. Microsoft Word - edible rock Activity Guidelines2

  6. Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. The first principle is the Principle of Superposition which.
