Tectosilicates, Carbonates, Oxides, & Accessory Minerals
This site from Tulane University consists of a lecture by Dr. Stephen Nelson on tectosilicate, oxide and carbonate minerals. The site features a table and description of the minerals in each group, including the nine types of SiO2, the different feldspars, and the calcite group. Optical and physical properties are explained, as well as the environment in which each mineral crystallizes.
Today in History
This sit efeatures a different person or event in history each day. Past features include Frederick Douglass, Woodrow Wilson, George Washington, Abraham Lincoln, Benjamin Banneker, Rosa Parks, Samuel Slater, Louisa May Alcott, Radio City Arts Hall, the Wright brothers' first flight, the Bill of Rights, the Gadsden Purchase, the Federal Reserve System, the Wounded Knee massacre, Pearl Harbor, the first controlled nuclear fission chain reaction, and more.
Map Collections: 1544-1996
This site offers thousands of digitized online maps. The collections are broken into seven categories, cities and towns, conservation and environment, discovery and exploration, immigration and settlement, military battles and campaigns, transportation and communication, and general maps.
Origins of American Animation
This site offers 21 animated films and 2 fragments, which span the years 1900 to 1921. The films include clay, puppet, and cut-out animation, as well as pen drawings. They point to a connection between newspaper comic strips and early animated films, as represented by Keeping Up With the Joneses, Krazy Kat, and The Katzenjammer Kids.
Diagramming the Study Site for Others
The purpose of this resource is to develop the best possible representation of the study site as a system. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Scaling Galileo's Solar System - Size of the Globes
In this activity students determine the sizes of the various planets in the solar system, scaled such that the orbit of Saturn fits on campus. The students also compare the planet sizes, given the scale, to the grain sizes of different sediment types. Students recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the second in a series of four on the Galilean Solar System, and was designed for an undergraduate class
Earth's history in 4.56 meters: constructing a timeline with calculator tape
In this short activity, students make a timeline of Earth's history using calculator tape. The tape is 4.56 meters long, so that one billion years is equal to one meter. This exercise is designed to introduce students to the scale of Earth's history and help them gain a familiarity with some major events. It also teaches about scaling, the metric system, as well as the concepts of large numbers and deep time. The activity may be used in an introductory geoscience course. Learning goals, context
Volcanoes is an interdisciplinary set of materials for grades 4-8. Through the story of the 1980 eruption of Mount St. Helens, students will answer fundamental questions about volcanoes: "What is a volcano?" "Where do volcanoes occur and why?" "What are the effects of volcanoes on the Earth system?" "What are the risks and the benefits of living near volcanoes?" "Can scientists forecast volcanic eruptions?" This teaching packet reflects the goals of the National Science Education Standards deve
Inertial Oscillation Model
The EJS Inertial Oscillation model displays the motion of a particle moving over the surface of an oblate spheroid. The spheroid is flattened to an ellipsoid of revolution because it is rotating, just as the Earth is flattened because it is rotating. The particle is confined to motion along the surface by the spheroid's gravity; the motion parallel to the surface is treated as frictionless. The simulation shows simultaneously the motion with respect to the inertial coordinate system, and the mot
Great Circles Model
The EJS Great Circles model displays the frictionless motion of a particle that is constrained to follow the surface of a perfect sphere. The sphere rotates underneath the particle, but since there is no friction, and the sphere is perfectly spherical, the motion of the particle is not influenced by the sphere. The simulation shows simultaneously the trajectory with respect to the inertial coordinate system, and the trajectory as seen from a point of view that is co-rotating with the sphere. The
Proving (a Theorem) and Disproving (a Theory). Applying the Pythagorean Theorem to Real Life
In this lesson, students share thoughts about careers and gender roles. They then work together to prepare a proof of the Pythagorean theorem and synthesize their learning by preparing a creative representation of Pythagoras' ideas.
Cardiovascular Construction Kit
The Cardiovascular Construction Kit (CVCK) allows students to design and construct a wide range of cardiovascular systems, testing each one to see how it behaves and whether it could actually exist and survive in a real organism. CVCK provides a set of basic components, e.g., pumps, vessels, capillaries and so on, which may be pieced together to construct a cardiovascular system. Gauges and measurement techniques are provided so you can draw conclusions from your experiments. Note: CVCK is a MAC
This interactive L-system simulation produces visualizations of tree forms based on data from specimens in the field or laboratory.
The History of Luxury Car Bentley
This is a brief history of the Bentley automobile. It is almost an advertisement for the brand. This video lacks details as to costs and performance, but may have value to motivate those students who are interested in cars and who wish to work with them.
Access to the Internet
Using the Internet depends, in the first instance, on access to the network. The initial emergence of "the Internet" in the early 1990s, from the increasing connectivity of a series of university and government networks alongside private services like America Online, Prodigy, and CompuServe, occurred almost entirely across slow dial-up modem connections over telephone wires. Sufficient for email, Usenet news groups, transferring relatively small files, and later viewing simple web pages, slow tr
Pio Pico Researchers Participatory Action Research: From Classroom to Community, Transforming Teachi
Emily Wolk is a teacher of a group of students, aged 8-11 years old, called the Pio Pico Researchers. Together, since the group started in 1996, the group convinced the city of Santa Ana to install a signal light at one of the most dangerous intersections in the city, in the immediate vicinity of Pio Pico School. Wolk used an alternative inquiry method called Participatory Action-Research (PAR) with her students. The children used radar guns, plotted data on a computerized mapping system called
Earth Exploration Toolbook Chapter: Visualizing Carbon Pathways
This EET Chapter will introduce you to visualization capabilities available through NASA's Earth Observatory. You'll build several animations of satellite data that illustrate carbon pathways through the Earth system. For instance, you'll build animations of fire images that indicate carbon is being released into the atmosphere. You'll also make animations of plant productivity images that indicate carbon is being removed from the atmosphere and locked into the biosphere. After you've built anim
This site explores the formation of stars and planets and the quest for a habitable planet. Create a virtual a community of microorganisms. Try to build the perfect solar system. See how planets react with one another, and how some planets help keep our solar system stable. Look at images: see if you can recognize life.
Trust, Transparency And Care.
The lecture will discuss some of the issues facing the health and social care system following the election.
