Geochemistry of Igneous Rocks
This website contains an abundance of data on the geochemistry of igneous rocks. The site provides very brief descriptions of many types of terrestrial and lunar igneous rocks, their regional distribution and classification, and examples of their geochemical trends and fingerprints. Graphs that plot the geochemical composition of both terrestrial and extraterrestrial igneous rocks are also featured. This site could be useful for upper level geology students doing independent research, as well as
General Classification of Igneous Rocks
These lecture notes are part of a series of lectures available on the geology department website at Tulane University. Topics covered include criteria for the classification of igneous rocks, field identification of minerals present in hand sample, thin section examination and chemical analysis. The general chemical classification covers silica content (silica saturation), aluminum saturation, and alkaline and subalkaline rocks. This resource is part of the Teaching Petrology collection. http://
Continental Alkaline Magmatism
This 32 slide PowerPoint presentation presents a list of alkaline rocks followed by an in depth look at continental alkaline magmatism of the East African Rift system. A chemical, geographic, and structural look at carbonatites follows. The presentation progresses through discussions of lamproites, lamprophyres, and kimberlites. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Classification of Igneous Rocks
This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers classification of phaneritic igneous rocks, gabbroic rocks, ultramafic rocks, pyroclastic rocks and volcanic rocks using triangular diagrams, and classification of igneous rocks based on total alkalis vs. silica. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
Practical Aspects of Mineral Thermobarometry
These pages provide information, tutorial material and worked examples for petrology students interested in extracting pressure-temperature information from rocks. It is assumed that you have completed a typical undergraduate petrology course. The sequence of topics, listed below, progresses from the acquisition of mineral analyses to computer-based P-T and phase diagram calculations.
A Classification of Metamorphic Rocks
This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well.
Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.
Exploring Radiometric Dating with Dice
In this lab, students use dice to simulate radioactive decay. Students create a standard decay curve for a fictional element, calculate the half-life of this element, and, using the information their graph, "date" rocks that contain the new element. The use of dice has some advantages over similar exercises because the half-life is not immediately obvious to students and they will need to experimentally determine it. Learning goals, context for use, teaching tips, materials, assessment tips and
Density of Rocks - How Large Is a Ton of Rock?
This module addresses how to determine the size of a ton of rock of a given composition and invites the student to figure out how to solve the problem. Students recreate spreadsheets, shown in a Powerpoint module, on their own with formulas that answer various pieces of the overall question. This module is the third in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students look at geological questions mathematically and may spend
Developed for first grade. Students will make a substance and use scientific observations, as well as their senses to classify Oobleck and its ingredients as solid, liquid, or gas. Students will notice that Oobleck bounces and is very tangible, but also very gooey and slimy all at the same time. Students will be amazed how Oobleck can fit so many different categories. Students will love playing with Oobleck after taking pride in making it! Biology In Elementary Schools is a Saint Michael's Coll
Minerals, Crystals, and Gems: Stepping Stones to Inquiry
This site introduces students to mineral science and the scientific process -- observing things, forming hypotheses, and drawing conclusions. Students watch crystals grow, go on a scavenger hunt for minerals, and create a classroom exhibit of rocks and minerals (for Grades 3-8).

COSEE Great Lakes Workshops
These asynchronous workshops focus on environmental topics related to the Great Lakes region. Subjects covered include: The solid earth system; The bedrock and formation of the Great Lakes; Life and Rocks: Current geological processes; Human impacts [vice-versa!]; and Ocean/lake deep exploration (sink holes, underwater archeology, NOAA's exploration book) studying the bottom, characteristics of the water at depth.

Essential Science for Teachers: Earth and Space Science: Session 2. Every Rock Tells A Story
How can we use rocks to understand events in the Earths past? In this session, participants explore the processes that form sedimentary rocks, learn how fossils are preserved, and are introduced to the theory of plate tectonics.,Students and scientists explore the questions: How do rocks form? How can we determine how old rocks are?
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer shows the student two different representations of mountains, one smooth and one jagged, and asks her to describe what she sees. As she describes a volcano, the interviewer probes to find out why she thinks it is a volcano, whether a volcano is a mountain, and how a volcano forms a mountain.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is trying to find out if the student has prior knowledge about types of rocks by asking her about the stripes on the rock and why she thinks it is striped. She uses the word "metamorphic" and goes on to explain what a metamorphic rock is. The interviewer probes further by asking her why rocks get pressed together and where the stripes may have come from. He then shows her a picture
Introduction and Textures and Structures of Igneous Rock
