This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers the origin of basaltic magmas. Two types of basalt in ocean basins are compared (tholeiitic and alkaline). Composition of mantle-derived magmas and sources of mantle material are listed. Discussion of how the mantle melts, touching on the contribution of volatiles, pressure and composition, is included. The slide show includes figures comparing enriched vs. depleted mantle.

Igneous Rocks of the Ocean Basins
These lecture notes introduce magmatism and petrology as they relate to the oceanic lithosphere. The notes cover ophiolite sequences and types of volcanic settings found in ocean basins. A section about basalt includes discussion of location, composition and origin of mid-ocean ridge basalts. Ocean island basalts are further discussed with regards to occurrence, composition and origin. These notes include graphs, maps and phase diagrams.

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
This site, which accompanies an introductory structural geology class at the University of Leeds, UK, contains information on faults. Topics include normal faults, thrust faults, strike-slip faults, faults and stress, and soft-linked fault systems. The site features explanations of the three basic types of faults with informative diagrams and a photo gallery.
This NASA site explains the three major types of atmospheric aerosols - volcanic emissions, desert dust, and anthropogenic aerosols - and how they affect global climate. The site discusses the generation and atmospheric distribution of these aerosols, as well as the chemical and physical processes by which they create global cooling.
This 11-slide PowerPoint presentation presents a short succession of schematic diagrams illustrating the structural evolution of anorthosites. The slides discuss the relative abundance of rare earth elements, describe six types of anorthosite occurrence, and contain pictures showing anorthositic texture. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html
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.

Environmental Catalyst Module
In the Environmental Catalysis Module, a joint project with the Institute for Environmental Catalysis at Northwestern University, students learn what a catalyst is and become aware of the use of catalysis to promote environmental protection. Besides introducing the concept of catalysis, the module also focuses other issues such as catalytic selectivity, specificity, poisoning, condition optimization, and waste minimization. The first activity of the module introduces the concept of catalysis in
Language arts: elementary grammar
This module contains three different kinds of exercise which test elementary level grammar skills in English. The exercises concentrate on identifying parts of speech, different types of sentences and sentence completion.
Japanese: Kanji - Lesson 1
The purpose of this tutor is to assist people who are studying the meaning and writing of the kanji (Japanese characters) following James W. Heisig's method called 'Remembering the Kanji'. 15 Kanji characters are taught, beginning with the numbers 1 to 10. The module makes use of a kanji-matching game as well as multiple-choice and text entry question types. Hints and timers are sometimes used.
Elementary Mathematics: Times Tables I
Learn and practice times tables. This is the first of two modules and practices the 2, 3, 4, 5 and 10 times tables. It includes multiplication testing, corresponding division exercises and missing-operand exercises as part of a range of different task types designed to develop an all-round understanding of the times tables.
British History from the Romans to the Normans
A learning module about early British history, orientated towards primary school. The module is intended for use in conjunction with a suitable children's book on the subject. When using this module, it is recommended to make books available to the child for reference while working with the module. It may be helpful to work with your child and help them find the answers in the book(s) at first. The module includes questions from the departure of the Romans and the first arrival of the Angles and
Refine your English vocabulary, starting with easy words for children, and ending with the most complex of lexical rarities. About 500 words are contained in the module's internal database, which is used to generate unlimited combinations of randomised tasks. Question types include many games, such as hangman, anagrams and memory. More conventional tasks such as pair matching and multiple choice are also included. The vocabulary is divided into different levels, beginning with easier levels suit
A learning module on ancient Egypt, suitable for primary school upwards. The module covers a wide variety of basic facts about Ancient Egypt, including pharaohs, pyramids and lifestyle. Some media resources are included. The task types are extremely varied, including word games as well as more conventional multiple choice, gapfill and text response types.
Single-Celled Organisms Unit
This Project Oceanography lesson plan (PDF) explores the symbiotic relationships of single-celled organisms. In this activity, students will compare and contrast three types of symbiotic relationships, describe the relationship between zooxanthellae (a dinoflagellate) and coral, and explain the effects of nitrogen-fixing bacteria on their symbiotic partners. It begins with an introduction to symbiotic relationships, the dinoflagellate/coral system, and cyanobacteria, and then features an interac
The material found at this site provides original, multidisciplinary, inquiry-based ideas to help enrich science teaching using the world famous Great Salt Lake as a springboard theme. During the lesson students will have the opportunity to view two types of algae (fresh water and Great Salt Lake species) under 400x magnification with a compound microscope. Students will make observations and record their observations on a recording sheet where they will describe what they see through drawing a
Land Cover Change Detection Protocol
The purpose of the resource is to investigate changes in the major land cover types of Study Sites by examining Landsat satellite images acquired years apart.
Just Passing Through
The purpose of this resource is to develop an understanding of some of the relationships between soils of different types and water. Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes through the soil and observing changes to the clarity of the water and to the characteristics of the soil.
Community Health Nursing
By the end of this course the students should be able to: Identify the root of Community Health Nursing; identify supportive organizations; differentiate between Public Health Nurse and Community Health Nurse; explain Community Health Nursing; describe the qualities of the Community Health Nurse; describe the different types of community; differentiate between urban and rural communities and outline community profile; explain community entry; describe the preparations made before a community is
USGS Bedform Sedimentology
This site presents a collection of photographs, short movies, classifications, and computer-generated images for identifying various types of bedforms. Viewing of movies and 3D dynamic computer-modeled bedforms allows students to observe the creation, internal structure, and migration of bedforms through time. Photographs depict these processes in the real world. In addition, software for simulating ripple and dune bedforms and crossbedding is available for a free download. The site also feature
