Curated OER
Fossils and Lithologic Units
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...
Curated OER
Evolution and the Fossil Record
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...

Diversity of Life: Geologic Time Scale
Students investigate the history of Earth by creating a geologic time scale. For 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...

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...
Curated OER
The Geologic TimeString
Students 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...

Tracing Highs and Lows in San Francisco
On a topographic map, students identify the scale bar, north arrow, and contour interval. They then locate a hill on the map and make note of the contour lines. Students then locate other places with similar contour line patterns....
Curated OER
Hudson Valley Rocks
Students identify each of the rocks provided and locate where in the valley they are found. They explain why the rocks came to be as they are in each location. In addition, they relate the exercise to how the Hudson Valley's geologic...

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