Geologic Time Scale II

After reading a passage about geological time and fossil evidence, Earth historians write answers to six questions about what they learned. They are also directed to design a board game that would teach players about the geological time...

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...

In this geologic time scale activity, 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...

In this history of life worksheet, students explain how fossils form and how they can be interpreted. Students fill in the missing eras and periods in the geologic time scale provided.

Here is a straighforward and visually appealing presentation for your middle school earth science pupils. It introduces three types of fossils, relative vs. absolute dating, and the different eras of Earth's history. The eras are further...

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...

Students construct a geologic timeline the size of a football field. They work in small groups to calculate the yardage for significant events in the Earth's history and then as a class pace out all of the events.

Learners investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.

Students 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 to...

Students develop a sense of geologic ("deep") time and the ways in which Earth scientists construct the geologic time scale. They study he major events that shaped Earth, including the origin and evolution of its lithosphere, atmosphere,...
