AAA Doesn't work
An interactive applet and associated web page that shows that angle-angle-angle (AAA) is not enough to prove congruence. The applet shows two triangles, one of which can be dragged to resize it, showing that although they have the same angles they are not the same size and thus not congruent. The web page describes all this and has links to other related pages. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference I
Radius of an Arc or Segment
An interactive applet and associated web page that describe the radius of an arc and how to derive it from the width and height of the segment defined by that arc. A practical use is described for finding the radius of a circular arch given its other dimensions. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
Perimeter of a triangle
A web page and interactive applet show how to compute the perimeter of a triangle. A triangle is shown that can be resized by dragging its vertices. As you drag, the perimeter is continuously recalculated. Text on the page explains that the perimeter is the sum of the sides. For those who prefer it, in a formula that is given. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference interactive geometry reference book
Working in Paterson: Occupational Heritage in an Urban Setting
Working in Paterson: Occupational Heritage in an Urban Setting presents 470 interview excerpts and 3882 photographs from the Working in Paterson Folklife Project of the American Folklife Center at the Library of Congress. The four-month study of occupational culture in Paterson, New Jersey, was conducted in 1994. Paterson is considered to be the cradle of the Industrial Revolution in America. It was founded in 1791 by the Society for Establishing Useful Manufactures (S.U.M.), a group that had U.
Reel American History Project
The general goal of the Reel American History project is to foster critical thinking about a matter of enduring cultural attention, especially where young people are concerned: the formation of our national identity.
Reel American History is designed to be a "Collaborative Shared Resource". It aims at being a large, ongoing, cumulative, collaborative project that involves many students and many faculty over a long period of time. We strive to engage students in authentic learning – making st
Vertebrates are Cool!
As an introductory activity, students will read the eBook Vertebrates and then keep it as reference source. They will discuss the different animal species found in vertebrates. As a project, students will pick a vertebrate and create an eBook with one photo about that vertebrate. They will research the vertebrate both in the media center and on Web pages downloaded with FlingIt. Students will give an oral report of the special characteristics of their vertebrate and then beam their eBooks to oth
Hermann Hesse's Siddhartha
Almost all major works in philosophy and literature are accessible via online sources on the Internet. Fortunately, much of the best work in philosophy and literature is available in the public domain. A translation of Herman Hesse's Siddhartha, in particular, became available through Project Gutenberg by Michael Pullen. This edited version of that text is subject to the legal notice following the title page referencing the GFDL License. By placing this edited reading selection under the GFDL, t
Lenz's Law Demonstration Device - The Ring Fling Machine
The instructions provided here are of devices that have been built for Jefferson Lab's Science Education program. The difficulty of construction varies from project to project. Anyone attempting to construct these devices needs to know and understand how to safely operate the tools required to construct them. If you do not know how to properly operate power tools or a soldering iron, you should not attempt to build any of these devices.
Go Far Car Ramps
Developed for use with Jefferson Lab's Go Far Cars experiment, this simple ramp can easily be set to four different height settings. The ramp settings are uniformly spaced, so the amount of gravitational potential energy given to an object at the top of the ramp increases by a constant amount as the ramp is placed at higher settings. The instructions provided here are of devices that have been built for Jefferson Lab's Science Education program. The difficulty of construction varies from project

Cloud: Wild Stallion of the Rockies
Filmed in the mountains of Montana, this poignant, engrossing chronicle focuses on an extraordinary stallion, whose life has been recorded since his birth in the wild in 1995 by Emmy-winning filmmaker Ginger Kathrens. (50:52)
Image-ing Our Foremothers: Art as a Means of Connecting with Women's History
This is an 8 week experience for the college student that begins by setting a learning context through using library resources, especially online databases, for locating images and art that reflect a chosen research topic and creating a mural that demonstrates the students’ comprehension of the chosen topic. The experience includes conducting research on 3 significant events or people in women’s US history. The written research will be accompanied by images or art that the student has chosen
Values at Play
The Values at Play (VAP) project was conceived with the intent of investigating how video game designers consciously and unconsciously embed social values into video games through narratives and game mechanics. This curriculum, a corollary of the research project, will introduce designers to a systematic method for discovering, analyzing, and integrating values into their design work. All of the materials associated with the curriculum are available on this page as downloadable documents.
River City Project
As visitors to River City, students travel back in time, bringing their 21st century skills and technology to address 19th century problems. With funding from the National Science Foundation, we have developed an interactive computer simulation for middle grades science students to learn scientific inquiry and 21st century skills. River City has the look and feel of a video game but contains content developed from National Science Education Standards, National Educational Technology Standards, a
Tropospheric Ozone and Smoke from Earth Probe TOMS: Indonesia
Researchers have discovered that smoke and smog move in different ways through the atmosphere. A series of unusual events several years ago created a blanket of pollution over the Indian Ocean. In this animation, significant smog or tropospheric ozone is represented by red and green and regions of significant smoke index are in shades of white and gray.
Using Mars in a Teaching Plan
This area of the Web site is for teachers and those preparing lesson plans. It is our intention to provide enough material in enough subject areas to keep a class occupied for up to a whole term on a major project with "Exploring Mars" as its theme. That is not to say that this is how you should use the site, you may wish simply to pick something for a single lesson. That can be done too.
GLOBE Cave Protocol Field Guide: Comparing Surface and Subterranean Environments
The GLOBE Cave Protocol Field Guide utilizes existing GLOBE protocols to explore an extreme environment. Caves provide an opportunity to utilize GLOBE protocols to investigate underground environments and compare them to surface environments. Outside the cave, students record elevation, MUC, latitude and longitude, air temperature, relative humidity and air pressure. Inside the cave, students record air temperature, relative humidity and air pressure as well as observe and describe cave features
Exploring Business
The author's goals in writing Exploring Business were simple: (1) introduce students to business in an exciting way and (2) provide faculty with a fully developed teaching package that allows them to do the former. Toward those ends, the following features are included in this text:1- Integrated (Optional) Nike Case Study: A Nike case study is available for instructors who wish to introduce students to business using an exciting and integrated case. Through an in-depth study of a real company, s
