Decoding the Past: The Work of Archaeologists
This site introduces students to archeology -- the study of material remains to learn about past human experiences. This lesson (Grades 3-8) discusses various challenges of an archaeologist: locating a site that will yield clues about the people who once lived there, conducting excavations, and more. Students identify artifacts from a contemporary setting, describe the function of each artifact, identify methods for dating soil layers, and interpret soil profiles.
Oscillator Chain Model
The EJS Oscillator Chain model shows a one-dimensional linear array of coupled harmonic oscillators with fixed ends. This model can be used to study the propagation of waves in a continuous medium and the vibrational modes of a crystalline lattice. The EJS model shown here contains 31 coupled oscillators equally spaced within the interval [0, 2 pi] with fixed ends.
Maps of Indian Territory, the Dawes Act, and Will Rogers' Enrollment Case File
This lesson encourages students to study a variety of documents to understand the impact of a particular piece of legislation and relates to the powers granted to Congress in Article I, Section 8 , of the Constitution, related to making laws. It correlates to the National History Standards and the National Standards for Civics and Social Sciences. It also has cross-curricular connections with with history, government, global studies, and music.
Entrepreneurship: The Real-Time Case Study
As you read this, the managers of a new high-tech company, (to be announced), are striving to achieve the entrepreneurial dream. On a special website you will follow that company, and see their progress week by week. But you will do more than just watch. You will be actively engaged with the company, analyzing its problems, and making input. You will be participating in an in-depth, real-time case study. Unlike traditional case studies, this real-time case will dig deeply into one company during

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

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
Resistan
Resistan is a mechanistic simulation model of the process of selection of fungicide-resistant biotypes of a hypothetical fungal pathogen of a hypothetical crop.
The fungus is a polycyclic organism with many generations per season. There is no genetic component in this simulator. Reproduction is assumed to be asexual. A small proportion of the initial inoculum is designated as the fungicide-resistant biotype at the start of the season, and the response of that population to various fungicide spr
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity.
By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown.
EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode

Food Interaction Study
This dataset comes from a study of 8 healthy males randomly assigned to a two-period crossover design, in which they either fasted and then ate, or ate and then fasted. They were given one dose of a drug, blood samples were collected and data on plasma levels were collected. Questions from this study refer to the absorption of the drug. A text file version of the data is found in the relation link.
Hysteria Over Pfiesteria
Students will be guided through an investigation of the Pfiesteria outbreaks through a variety of approaches employing writing, math, drawing, summarizing and deductive skills. As students assimilate details of the Pfiesteria problem, they will begin to develop a multifaceted understanding of the issue and its potential links to nonpoint source pollution. In Exercise II, they study the spatial and temporal distribution of Pfiesteria outbreaks in an effort to explore reasons for the connection be
Scaffolding: A model for learner support in an online teaching environment
'In the design of online teaching environments, considerable attention has been paid to the nature of the interface and to the streamlining of activities for learners to engage with. Much less attention has been given however to the nature of the learner support system that is created for novice users learning online. Support systems are essential for learners to engage in the processes of learning and need to be developed in response to needs. It is also imperative that a range of support syste

Element Concentration Game
The computer will display a number of cards with the names and symbols of the elements. After you have had time to study the cards, the computer will flip them over and ask you to find a particular element. Click on the card that contains that element.
Electrostatics
Students use a Although atoms contain both negatively and positively charged particles, they do so in equal amounts and carry no net charge. This balance can be temporarily disrupted by rubbing one material against another. One device, known as a Van de Graaff generator, uses a fast moving rubber belt to charge a metallic dome to nearly 200,000 Volts. This activity uses a Van de Graaff generator to study the behavior of electrical charges.
