AP: Chapter 25: Phylogeny and Systematics
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 worksheet takes a straightforward and...
Curated OER
Geologic Timelines
Middle schoolers 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...
Curated OER
Geologic Time Scale
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...
Curated OER
Understanding Geologic Time
Learners view Understanding Geologic Time on the Internet or by CD-Rom to explore the length of time that the Earth has existed.
Curated OER
Sequencing Time
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.
Curated OER
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
Geologic Time Scale
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.

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.
Curated OER
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...
