Earth Science Lesson Plans on Geologic Time
Springboard your fourth and fifth graders into the study geologic time. They will complete 7 activities to learn about geologic time and the topics most often associated with it: astronomy, creation, planet formation, volcanology,...

Geologic Time Scale Analogy
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.

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.

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...

Making The Geologic Time Scale Real
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.
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
Science NetLinks: Fossils and Geologic Time
Students investigate the development of the geologic time scale. Also, to introduce them to the major time periods in earth's history, as well as to the role fossils play in helping us understand this history.
Curated OER
Making The Geologic Time Scale Real
Young scholars are assigned significant geologic events in Earth's history. They convert the date of the events into distances and then space themselves (on an outside playing field) away from other groups, to represent time between...
Howard Hughes Medical Institute
EarthViewer
Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion years ago to...

Time Machine: Evolution, Geology
Students are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.
Howard Hughes Medical Institute
Following the Trail of Evidence
One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...
Biology in Motion
Organize-It
Many pupils struggle to categorize and organize related content. Multiple quizzes on a variety of topics offer practice for these specific skills. Scholars move items around until they think each is placed in the proper position....
Curated OER
Timeline
Young scholars develop a timeline that depicts geologic development and the history of life. They write an interpretive analysis essay that discusses and reflects on their observations.
Curated OER
Assessment & Evaluation
Seventh graders study elapsed time, radioactive decay and half-life. In this time machine lesson students complete several activities and view a presentation.
Curated OER
Desalination: Creating a Solar Still
To better understand how solar power can aid in creating desalinated drinking water, the class creates a model still. They will build a model of a solar still, make observations, and discuss how the process works. While the idea behind...

No bones About It -A Mosasaur
Students model a paleontologist's activities. They identify dinosaur bones and reassemble them into a skeleton of an extinct reptile.
Curated OER
Half Life Lab
Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
Curated OER
Investigating the Biosphere With Planetary Models
Learners create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to investigate in...
Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
Investigating the Biosphere with Planetary Models
Pupils model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.

Giants of the Protozoa
Students describe and define xenophyophores. In this protozoa lesson students divide into groups and complete a lab activity.
