86 slide PowerPoint on igneous, sedimentary, and metamorphic rocks. See preview! Starting with the rock cycle, the PowerPoint first focuses on igneous rocks and how to identify them based on the following properties: formation environment (intrusive versus extrusive), crystal habit, texture (coarse, fine, or glassy), mineral composition, and color. Rocks addressed are granite, basalt, gabbro, rhyolite, obsidian, pumice, diabase/diorite, and scoria.
The PowerPoint then focuses on sedimentary rocks and how to identify them based on the following properties: formation environment (rivers, shallow water environments, deep water environments, tropical environments, lakes), crystal/particle habit (pebbles, sand, silt, clay, carbon, and mineral crystals), texture (clastic, chemical - crystalline, organic - bioclastic), mineral composition, color, and fossil conduciveness. Rocks addressed are conglomerate, breccia, sandstone, limestone, bituminous coal, rock salt, rocky gypsum, chert, dolomite, geode, and shale. As an addition, the Marcellus Shale and environmental fracking is also explored.
To wrap it up, the PowerPoint then addresses metamorphic rocks and how to identify them based on the following properties: formation environment (regional metamorphism and contact metamorphism), crystal/particle habit (foliated versus non-foliated, crystallized, and carbonized) texture (coarse, fine, glassy), mineral composition, color, and density. Rocks addressed are granite to gneiss, sandstone to quartzite, mica to schist, limestone to marble, shale to slate, and bituminous coal to anthracite coal. As an addition, the history of the Earth landmasses through plate tectonics is also examined.
This has been used as a pre-class, note organizer, lab prep, study guide, and review. This is an effective teaching tool one on one, in small groups, and as a class when using a Smart Board/Promethean Board/Projection.
A great addition to your geology teaching library from middle school to undergraduate introductory geology courses.
This work has also been shared at workshops, in-services, and conferences.
Great feedback from parents, teachers, administrators, and curriculum field professionals.
Applicable to many state science assessments and benchmarks.
Has been applied to state mandated North Carolina end of year tests for science in grades 5 and 8.
Even used by teachers in New York State as a preparation for the Earth Science Grade 9 Regents Exam.
Our goal is your satisfaction! If you have any questions or concerns, please do not hesitate to contact us and we will promptly assist you. Your feedback is very valuable to us as we strive to produce the highest quality products possible.
