Geologic Time Scale

Using meters as years, your class works together to map out the geologic time scale on a football field. Plenty of background information is included in this lesson plan as well as several resource links and a student worksheet. Your...

Practicing paleontologists map the geologic time scale, simulate the formation of sedimentary rock, and analyze fossil data. Instructions for four activities and five assessment choices are provided for the teacher. This comprehensive...

How do scientists know the history of Earth before humans—or any mammals—existed? An epic "Eons" series video explains the larger history of geologic time. It highlights the eons, eras, periods, epochs, and ages scientists use to divide...

In this geologic time scale worksheet, students are given a list of terms and eras which they use to complete a time scale. They classify organic and inorganic changes that took place in the Precambrian era, the Cenozoic era, the...

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.

In this geologic time scale worksheet, students use a word bank to complete the geologic time scale provided. Students fill in the chart as it relates to the geologic time scale.

Students view Understanding Geologic Time on the Internet or by CD-Rom to explore the length of time that the Earth has existed.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-ESS1-4: geologic time scale.

Students research the geologic time scales and the appearance of animals and plants during these eras. They complete a chart indicating the era, period and major events.

Students place events in sequence and assign relative times to each event. They gain an understanding of relative and numerical time and become familiar with the methods used by scientists to develop the Geologic Time Scale.
