The list of 25 concepts is divided into seven topic areas, including the Nature of Earth Science, which contains items 21-25.Geologic Time Scale This information about geologic time and the geologic time scale defines the terms relative time (chronostratic) and absolute time (chronometric).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.There are links to texts, graphics, interactive presentations, and online courses for teachers. These maps illustrate connections between concepts and across grade levels.Use them to contextualize and sequence your instruction.
This project synthesized these ideas into a compact and defensible list.The resources in this section are thus either a subdivision of a larger earth science resource or the larger resource within which geologic time is addressed.Parts of some of these resources are appropriate for students, while others are more appropriate for teachers or more advanced learners only.Through this approach, students are challenged to conceptualize the geologic time scale by comparing it to a student-produced time scale for an older adult’s life.
This formative assessment allows the teacher to alter instruction based on students’ feedback.Geologic Time: Online Edition An online edition of a general interest publication from the U. Geological Survey gives an overview of the concepts associated with the age of the earth.
