Serc: A Constructivist Teaching Model for Conceptualizing Geologic Time

Students investigate the history of Earth by creating a geologic time scale.  In this Earth History lesson, students practice sequencing events in their life as a way to get familiar with creating a time scale.  Students...

Students examine geologic time to scale. In this geologic time lesson, students create a time-scale metaphor that shows some of the Earth's important events. Students present their metaphor to the class.

Time can be relative but sometimes it is relevant. Large numbers are difficult for pupils to imagine ... and large time scale even more so. A video presentation from the Good Thinking PD series offers tips for teachers to give learners a...

Students design, construct and interpret a model of geologic time and investigate change through geologic time.

The Next Generation Science Standards list Developing and Using Models as the second science and engineering practice. The video explains conceptual models and the expectations for K-12th grade scholars. It highlights the progression of...

A detailed set of exercises (downloadable) that guide students in developing an understanding of how scientists have created the geologic time scale.

Scientific models help explain ideas and concepts to non-experts. The online activity covers conceptual, mathematical, and physical models. Through four multiple-choice questions and three discussion questions, scholars gain a deeper...

This activity is specifically designed for a field trip to Drayton Hall, which is a historic plantation near Charleston, South Carolina. It does provide a model of how a similar activity could be designed for a local area, and there are...

Young scholars identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative...

Through five lessons, students are introduced to all facets of the rock cycle. Topics include rock and mineral types, material stresses and weathering, geologic time and fossil formation, the Earth's crust and tectonic plates, and soil...
