Twelve Stones portrays the heart of Heifer's work - Passing on the Gift ÂŽ - and shows the transformation of a community of women in Nepal from helplessness to hope through Heifer International. This is a preview clip of a documentary produced by Sandy Smolen.
This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
Students are employees of a unit of the United Nations responsible for coordinating disaster relief after a major disaster (the 2004 Asian Earthquake and Tsunami) occurs. The agency needs to understand the situation in each country so that it can coordinate the work of various governments and NGO (nongovernmental organizations) working in the affected area.
This site from About, Inc. is a collection of links to geologic articles and resources.
This exercise is intended to connect students to geology and to remind them of the diverse ways in which people, including geoscientists, relate to rocks. Groups of students are asked to examine rock samples from specific perspectives such as sculptors, landowners or geologists, and then present relevant observations and questions. Next, individuals write one-minute papers summarizing what they have learned and evaluating the activity. On this Starting Point page, users can access information about the exercise's learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered.
In this lab, each student or small student group "adopts" a different outcrop or road cut, describing and interpreting both the outcrop scale features and hand specimens. This website provides a context for the use of this lab, and describes learning goals, teaching notes and assessment. It also includes downloadable handouts and other teaching materials.
Earthquakes are natural phenomena that can cause immense human suffering because of intense ground shaking and are consequently of great societal importance. Earthquakes are also important because the seismic waves that generate the ground shaking provide scientists with important information about Plate Tectonics and geology, in particular information about the structure and composition of our planet and how the insides of the planet are deforming. In this course, earthquakes in Africa and the seismic waves they generate are used to help you to learn about the geology of Africa and how the earth beneath the African continent is being deformed by Plate Tectonics.
This site presents a collection of scientific learning resources for educators, parents, kids, after-school coordinators, informal learning center staff, and anyone else interested in teaching or learning about science. The site provides a searchable database of resource materials, including activities (computer based and otherwise), curriculum materials, articles, evidence and analytical tools and procedures, exhibition materials, reference lists, and special collections of resources organized around a particular theme. Users can browse resources by topic, sub-topic, grade level, or resource type. Each resource is displayed with a concise description that includes the title, resource type, grade level, and key concepts. Clicking the icon next to the title displays the full resource description. If available, other icons link to the resource in print format, Web format, or both.
This site contains 15 time-lapse QuickTime movies that show the experimental deformation behavior of octachloropropane. This compound shows similar microstructures to those found in quartzite, and thus is a nice analog for the deformation of rocks. The movies illustrate cataclastic deformation, grain boundary opening, formation of subgrains, subgrain boundary formation and grain boundary migration, ribbon formation, grain growth at zero strain rate, and grain boundary migration during high temperature deformation.
This is a laboratory course supplemented by lectures that focus on selected analytical facilities that are commonly used to determine the mineralogy, elemental abundance and isotopic ratios of Sr and Pb in rocks, soils, sediments and water.
Tsunami waves can be distinguished from ordinary ocean waves by many factors, including the tremendous amount of energy they carry, the great distance between their wave crests, and their capacity to travel at jetliner speeds across an entire ocean. In this interactive from NOVA Online, explore how the 2004 Indian Ocean tsunami -- the deadliest in recorded history -- was triggered, how its waves traveled thousands of kilometers largely unchanged, and what happened once the waves reached coastlines both near and far from their source.

In this interactive activity from NOVA Online, explore the main features of the Nyiragongo volcano, located in the Democratic Republic of Congo, and learn what risks it poses to the 500,000 people who live in its shadow. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
This short film uses graphics to provide an introduction to the physical causes of earthquakes, and to explore how the way we build and manage our cities determines their vulnerability to a seismic strike.
It was created with the UK GCSE and A' Level curricula in mind.
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
In this jigsaw-method activity on subduction zone volcanism, students apply lessons learned from four historic eruptions to the volcanic hazards associated with Mt. Rainier in the Pacific Northwest.
This USGS site explains what an aquifer is and defines the different types of aquifers based on six principal lithologies; sandstone, carbonate, sandstone-carbonate, igneous and metamorphic, sand and gravel, and other rock types. The site features maps and descriptions of the major aquifers in the United States as well as general information about groundwater occurrence and quality. The site also provides links to additional maps and data about specific aquifers across the nation.
In this Science NetLinks lesson, students determine what artifacts are, how they are discovered, and what information can be learned from them. They also learn how artifacts are initially buried and then excavated. This lesson is one of a two-part series on archaeology.
Through a higher-order integration of concepts and observations, students can combine information from several field labs, all discussed in the Starting Point collection, to construct an overall geologic history of the local region. This site details the learning goals, teaching notes and materials, method of assessment, and context of use of this lab. It also provides links to additional references and resources.
This resource is a part of the USGS document entitled "Preliminary Compilation of Descriptive Geoenvironmental Mineral Deposit Models". This chapter of the document describes gold, silver and tellurium vein deposits. Topics include a summary of relevant geologic, environmental, and geophysical information, geologic factors that influence potential environmental effects, and environmental signatures.
This site is a lecture about crystal structure from Dr. Stephen Nelson at Tulane University. Topics include axial ratios, intercepts of crystal faces (Weiss Parameters), determination of the Miller Index of a crystal, the modified notation of hexagonal systems, which is referred to as Miller-Bravais Indices, and using the Miller Index notation to designate crystal forms. Tables and illustrations accompany the text.
