Sequencing Time
Learners 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.

Toilet Paper Geologic Time Scale
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.

Science Puzzlers, Twisters, and Teasers: The History of Life on Earth
A somewhat amusing assignment, this worksheet lists statements that an ancient organism may have made and asks learners to determine what geologic era that each may have lived in. It uses witty word puzzles and fill-in-the-blank-style...
Curated OER
My Time
Students create a timeline of their lives. In this timeline lesson, students discuss relative and absolute time. They use events in their lives to create categories on a timeline. They link this lesson to geologic timelines.

Geologic Time Scale
In this geologic time scale instructional activity, middle schoolers use a word bank to complete the geologic time scale provided. Students fill in the chart as it relates to the geologic time scale.
Curated OER
Change Through Time
In this evolution worksheet, learners will complete a table by writing in the era and biological event based on 4 different time periods of Earth's history. Students will answer 8 fill in the blank questions based on the different origin...
Curated OER
Geologic Time Scale
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.

Understanding the Geologic Timescale
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...

Time and Earth History Socratic Questions
Pupils 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,...

Presenting the Geologic Timescale
Students model the geologic timescale using distance as a metaphor for time. They write a summary of a major event or fossil organism. and station themselves and their summaries along a path within a gymnasium, and present their...

The Geologic TimeString
Learners create a simple tool to visualize geologic time. They create knots to represent the K/T, P/T and Precambrian boundaries in a 4.6 meter string with each millimeter representing one million years. They then refer back to this...
Curated OER
Making The Geologic Time Scale Real
Pupils 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.
Curated OER
Fossils and Geologic Time
Students explore the development of the geologic time scale. They examine the major time periods in earth's history. Students discuss the role fossils play in helping us understand history.
Curated OER
Modeling Geologic Time
Pupils design, construct and interpret a model of geologic time and investigate change through geologic time.

It's About Time
Students create their own timeline. In this social science lesson, students write the important events that happened in their lives on their timeline and then compare their timeline to Earth's timeline.

Change by Chance?
Sixth graders are able to see the role of chance in evolution. The activity is similar to the party game "gossip" or "telephone." Students start off with a drawing of an animal which changes as they pass their copies of the animal to...
