Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Molecular Dynamics Demonstration Model
The EJS Molecular Dynamics Demonstration model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws, approximated using the Verlet algorithm with the indicated Time step. For sufficiently small time steps dt, the system's total energy should be approximately conserved. Users can select various initial configurations using the drop down menu.
Body With Thruster Model
The Body with Thruster Model shows the motion of a disk with an attached rocket engine. You can drag the engine to change its distance from the center of the disk and you can adjust the thrust of the rocket engine using sliders. The mass of the rocket and its connecting rod are assumed to be negligible. The trajectory of this single-body model is intuitively challenging and difficult to visualize.
The EJS Helmholtz Coils Model shows a the magnetic field between two circular coils of wire. The default configuration, known as a Helmholtz coil, sets the separation distance D equal to the coil radius R. These values produce a nearly uniform magnetic field B between the coils.

Small Business and Entrepreneurship
The objective of this course is to teach you to apply the skills you have learned in the functional areas toward the goal of starting a business, i.e., becoming an entrepreneur. Working in teams, you will learn to identify, conceptualize, plan, finance, launch, manage and harvest new ventures. Finally, intrapreneurship, the application of entrepreneurial methods of management to established organizations, will also be discussed. Class discussion, readings, case studies, guest speakers, interview
Imagination, Creativity And Entrepreneurship
This is a course about the courage to create, and to risk making mistakes in the quest for ideas that lead to a true innovation of a product, service or process. Creativity is the central focus, which might be defined as "the application of a person's mental ability and curiosity to discover something new. The act of relating previously unrelated things." More specifically, we are concerned with capitalist creativity, which means that solutions must be generated that are profitable and reflect b
Entrepreneurship Consulting and Analysis
This course provides students an opportunity to practice action learning. Many instructors are advocates of action learning because they believe students can learn by doing. In this course, students will complete a project for a local entrepreneur. The project may be highly specialized or comprehensive in nature, depending upon the needs of the business.
Entrepreneurship and Digital Commerce
We are in the midst of a revolution in technology that is transforming significant segments of our economy and our society. The Internet, the World Wide Web, fiber optics, Internet telephony, MP3 compression, digital interactive television, wireless communications, streaming media and a host of other digital technologies are creating many opportunities to establish viable, sustainable new ventures. But as the rise and fall of the dot.com phenomenon has demonstrated there are some huge potholes i
Reporting America at War
These learning materials are designed to engage students in hands-on activities that stimulate them, and, most importantly, encourage critical thinking in the classroom. These educational activities in this section will provide high school social studies, media education and language arts teachers, as well as college journalism and communication educators with extensive lesson plans, resource materials, and discussion questions to introduce students to the world of war correspondence. Reporting
Ralph Bunche: An American Odyssey
Social studies teachers will find that the film presents an informative, complex and issue-oriented story that raises controversial questions and provides an exciting way to introduce a number of important concepts in 20th century United States and world history. It offers an opportunity to explore the historical background of current events and issues in the news today; the Middle East crisis, the struggle of developing nations to create stable economies and democratic governments, the legacy o
Understanding Your Water
Over two class periods, you will be guiding your students through the basics of water treatment -- both tap water treatment and sewage (or wastewater) treatment. To prepare for the lessons on the treatment process, the students will be researching where their drinking water comes from and where their wastewater goes once it goes down the drain for homework. After learning about their local water treatment and traditional tap water and sewage treatment processes, students will watch the NewsHour
From Page to Stage
Musical theater book writers, lyricists, and composers have long looked to literature for their inspiration and subject material. In this lesson, students will compare and contrast literary works and the musicals they inspired. Utilizing video clips and Web sites, students will compare specific passages from original texts to moments in Broadway musicals on which they were based, and analyze similarities and differences between the two. As a culminating activity, students will try their hand at
Hey, Mr. Producer!
It's not that uncommon for secondary school students to study the ups and downs of the stock market, but in this lesson, students will examine the economic roller coaster involved in the production of a Broadway musical. As an introduction to the lesson, students will read a series of online articles to investigate the similarities and differences between nonprofit theater production and Broadway, or commercial, theater production. They will view excerpts from the PBS series BROADWAY: THE AMERIC
The Shapes of Our World. Experimenting With the Language of Geometry
In this lesson, students play a game of charades as an experiment in non-verbal communication. They then create maps with directions that demonstrate their ability to utilize shapes and spatial relationships in a practical context. Their learning is culminated in a written critical essay about the universality of human understanding.
The on-line game aims at teaching children how to build safer villages and cities against disasters. Children will learn playing how the location and the construction materials of houses can make a difference when disasters strike and how early warning systems, evacuation plans and education can save lives. Children are the future architects, mayors, doctors, and parents of the world of tomorrow, if they know what to do to reduce the impact of disasters, they will create a safer world. Each scen
Literacy Education in Non-Formal Settings
The main objective of these handbooks is to build the capacities of facilitators and other literacy and non-formal education personnel to promote learning and development at the community level. The instructional packages include animations, video, posters, booklets and illustrations about literacy, saving money, health, environment and important everyday life issues.
Handbook for Teachers of Multi-Grade Classes: Improving Performance at the Primary Level
Multi-grade classes and single teacher schools have made it possible for many children in remote rural areas and communities to access education. However, the teachers teaching in these environments rarely receive training in how to deal with and manage the large numbers of pupils, of different ages and levels of learning, that they confront in their classes. These tools can assist teachers in this regard. This handbook comprises ten units, each one consisting of common experiences, case studies
