University Corporation for Atmospheric Research Abstract:

This informational tour offers students a basic understanding of geologic time, the evidence for events in the history of the Earth, relative and absolute dating techniques, and the significance of the Geologic Time Scale. Students move at a self-selected pace by answering questions correctly as they go. The teacher's guide contains all the details needed to use this computer activity, including handouts, a lesson plan, and assessment materials.

Internet Scout Project Abstract:

Through this University of California, Berkeley website, both students and teachers can understand the complexities of geologic time. Through interactive timetables, students can discover when key events occurred in the earth's history, the difference between relative and absolute time, the Law of Superposition, and the Geologic time scale. At the end of the tutorial, users can test their knowledge. Educators can find preparation steps, technical requirements, standards, and user tips. The website provides a list of terms, simplified version of the geologic time scale, quizzes, assessment materials, and other lesson plan ideas.
