Excerpts from the March on Washington, Part 1
This audio compilation, recorded live at the 1963 March on Washington, captures the voices of several civil rights leaders.
Parallel Axes Theorem
Fact-sheet with a worked example on the use of the parallel axes theorem.
Introduction to Axonometric Projection
This article on axonometric projection provides background reading on axonometric projection as it applies to Junior Certificate classes.
This field exercise determines the susceptibility of different rocks to weathering, and, using the dates on the tombstones, estimates some weathering rates. Placing the field lab in context for use, this site describes the learning goals, teaching notes and materials, assessment recommendations, and provides links to other resources and references.
Post-Settlement Erosion and Deposition
In this example, a field laboratory in introductory geology becomes a test of a hypothesis: Does the model proposed by Stanley Trimble for Coon Creek, Wisconsin adequately describe the history of post-European-settlement erosion and deposition in a small drainage in southeast Minnesota? This field lab is detailed on the site, which describes leaning goals, a context for this lab's use, teaching notes and downloadable handouts, and assessment recommendations. There are additional references and l
Starting Out With Earth History
This activity asks students to place 6-10 events in Earth history on a timeline, first working in small groups and then as a class. Then, through questions, important points such as how certain events are dated, where humanity fits in, and so forth, can be brought up. The Starting Point website builds a context for the exercise by detailing the learning goals, teaching notes and materials (downloadable), and additional resources.
Seeing the Invisible
Students will be instructed to make an observation of a flower (tulip) given the one stipulation that they will only be allowed to detect the parts of the plant that are green. Through observation and discussion, students will be led to understand that only seeing parts of the flower leads to an incomplete and even inaccurate understanding of its structure. Students will construct their own knowledge of the Sun emitting light above and below the visible spectrum by using UV beads to detect ultr
Building a Winogradsky Column Video Demonstration
This five-minute Quick Time video demonstrates how to build a Winogradsky Column. The video is published by NASA Quest and can be used as a teaching supplement to classroom activities including the Winogradsky Column. This video requires Quick Time player to view, which can be downloaded on site.
Video Gallery: Why Conserve Sharks?
This video gallery is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. Part of the Sharks and Rays: Myth and Reality seminar, Video Gallery: Why Conserve Sharks? features two brief videos, each with a printable PDF transcript:Resistance to Cancer discusses why sharks make an interesting model to look at when investigating resistance to cancer. Immune System looks at the Mote Marine Laboratory's projec
This site features a collection of visual resources about glaciers. Diagrams, images and animations reveal how a glacier forms, advances and retreats. These resources can be integrated into lectures, labs or other activities.
Lincoln Home National Historic Site: A Place of Growth and Memory
recounts the life of our 16th president. See photos of the house in Springfield, Illinois, that Abraham Lincoln, his wife, and family occupied for 17 years. Read news accounts of his departure for Washington, D.C., from Springfield and of his funeral. Learn about the series of events that led to his election as the first president born west of the Appalachians.
The Battle of Oriskany: Blood Shed a Stream Running Down
tells how long-standing prejudices and the Revolutionary War unleashed massive bloodshed among inhabitants of New York's Mohawk Valley. Located in rich farmland and at a strategic point in a fur trade route, the valley had been settled by European immigrants who had prospered from productive farms and lucrative trade. As war broke out, everyone had to choose sides: Rebel or Tory. It was not easy for many. Five hundred years of unity among the Six Nations was broken.
America's Space Program: Exploring a New Frontier
tells the story of America's journey to the moon. The creation of NASA, the Apollo vehicles, and the January 1967 tragedy are part of the story. On July 20, 1969, as the Eagle lunar module approached the moon, it became clear that the computer had chosen an unacceptable landing site -- a boulder-strewn crater. With 114 seconds of fuel left, astronauts Armstrong and Aldrin overrode the computers and manually landed the Eagle.
Survival of the Fittest Microbes: Examining the Conditions of One River and the Microbes that Thrive
In this lesson, created for grades 6 - 12, students learn about the harsh conditions of Spain's Rio Tinto River and research the microbes that nonetheless manage to thrive there. They then synthesize their knowledge by creating a reality television program set in the Rio Tinto in which the microbes are the "contestants." The lesson includes an article about the Rio Tinto with accompanying questions, a detailed classroom activity, vocabulary list, discussion questions, extension activities, inter
Knowledge technologies in context
This unit explores knowledge technologies, that is, software systems that can represent, interpret, formalize or interrogate phenomena and create models of how the world works. It demonstrates how a well designed system can have positive effects on the work 'ecosystem', potentially allowing more time for people to concentrate on their strengths. Emphasizing core concepts of representation, interpretation and situated use in context, this unit will help masters students and those involved in spec
Global Methane Isosurface Wave
An animation of a three-dimensional isosurface of global methane in the atmosphere evolving over time, from a global data assimilation model. The globe of the Earth starts out opaque, then becomes transparent in order to more clearly see the structure of the isosurface. The isosurface exhibits wave breaking in the southern hemisphere.
Annually Occurring Aerosol Features: Biomass Burning in South America from August through September
Aerosol index over South America from August 1, 1987 through September 30, 1987 as measured by the Nimbus-7 Total Ozone Mapping Spectrometer (TOMS)
In this unit materials you will learn about the history of Spain and the important place of Arab and Jewish cultures in Spanish history. You will study a number of language points to help you talk about history and will write descriptive texts using a variety of stylistic devices.
