Geologic Time Scale Teacher Resources

In this geologic time scale worksheet, learners 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...

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

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...

Students recreate and comprehend the geologic time scale. They discuss how long humans have been around on Earth. Students are shown the geologic time scale and its different parts. They work in groups to recreate the time scale.

In this geologic time scale learning exercise, 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.

In this geological time instructional activity, student use a geologic time scale to understand the difference between eons, eras, and periods. Then high schoolers complete 2 short answer questions.

Students examine and demonstrate the extent of geologic time compared to recent time. They develop a demonstration of geologic time using an unrolled roll of toilet paper, with each sheet of toilet paper representing 20 million years.

Middle schoolers 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.

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...

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.

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 complete their...

Young scholars 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.

Upper graders or entry college level learners use the provided article links to answer three questions regarding early modern human behavior. They compose short essay responses that accommodate each part of the overarching question,...

How has Earth changed over time? Pupils explore the topic in a differentiated instruction unit on the geological time scale. After a pre-assessment to gauge knowledge, class members divide into groups based on their ability levels and...

As a review or note taking guide, this resource wraps up a unit on the tree of life. Biology bigwigs define phylogeny and answer questions about the subsequent classification of organisms. The activity takes a straightforward and orderly...

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 research the geologic time scale. They create and recognize the importance of a geologic time line.

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.

If aliens visit Earth a million years from now, what will they find? Explore the Anthropocene epoch with a hard-hitting video. Viewers examine the changes humankind has made to the planet, how these overshadow events of the past, and...

Students create a timeline of geologic events of the Phanerozoic Eon. In this geologic timeline lesson, students view a handout that shows a timeline of the Earth's history. They create their own timeline of the Phanerozoic Eon with...

Students examine the geological time scale: the Earth is ancient; time can be divided into periods based on its fossil content.

In this history of life learning exercise, students will explore how mass extinctions have occurred on Earth, the different periods of the geological time scale, and scientists' use of fossil records. Students will complete 3 fill in the...

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

Students create a large (classroom-sized) timeline showing the history of life on Earth for the last 5 billion years. They are able to identify the events that are relevant to their taxonomic projects (the Origins and important...
