This resource allows students to practice finding mean, median, mode and range. Students are able to select parameters that include a number range, length of sequence, and an option to work on one or all including mean, median, mode and...

This textbook excerpt illustrates the reactions observed to occur between minerals and magma, and the order of these reactions during magma crystallization that was described by Norman Bowen in the 1920s.

Explains what active and passive continental margins are and where they can be found. Includes a world map showing their locations.

An 81-page slideshow that looks at the principles of geology with respect to relative dating, at different concepts describing geological processes, at absolute age and radiometric dating, at the eons and eras in the geologic time scale,...

An in-depth look at the structure and composition of Earth's mantle, with lots of visuals. Covers lithosphere, Mohorovicic discontinuity, asthenosphere, transition zone, lower mantle, the d double-prime region, mantle convection, mantle...

This is an in-depth activity where students create a rock layer formation using different colors of playdough and investigate the types of folds and rock formations that might occur. They take core samples through anticlines and...

A lengthy scholarly article that discusses the geologic time scale, its history of development, age-dating events that occurred in different eras, and how absolute and relative dating are used to assess the ages of the Earth and Moon....

This site was created by two geoscientists. They explain the Principles of Geology. These are general rules, or laws, that are used to determine how rocks were created and how they changed through time. They are also used to determine...

Understand the characteristics and features of Earth's core from this detailed article. Includes high-quality illustrations, a downloadable poster, a video, and links to other resources.

Explains what absolute dating is as compared to relative dating and how they can work together. The characteristics of several different radiometric methods are compared. Includes three short videos and an interactive where students...

Lots of information here about glaciation, types of glaciers, the formation of glacial ice, changes in glacier size, how glaciers move, glacial erosion, landforms produced by glaciers, glacial deposition and drift, effects of glaciation...

Extensive information about the geology of the Grand Canyon. Looks at some principles of geology evident there, forces that have shaped its geological features, how its valleys and canyons were formed, the characteristics of the Colorado...

A fantastic resource for learning about how ice cores are collected, the information we can learn from them about Earth's climate history, the types of research being done with them, and how they are stored. Includes lots of videos.

Featuring images of glacier formations, this interactive resource adapted from the National Park Service explains what glaciers are, where they are found, how they form, and how they move.

This site explains the research of the Ice Core Paleoclimatology Group. See how they are coring ice samples all around the world to help better understand Earth's changing climate. Provides links to teaching materials.

This set of lesson plans was developed to accompany Ground Rules: Mining Right for a Sustainable Future, a documentary film created by Caterpillar and Science North. They introduce students to the various phases involved in mining,...

This set of activities from the Milton J. Rubenstein Museum of Science & Technology has students investigating how relative dating and absolute dating methods are used to determine the age of rocks and fossils.
