The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that il
Herschel Infrared Experiment
Students perform a version of the 1800 experiment in which a form of radiation other than visible light was discovered by the famous astronomer Sir Frederick William Herschel.
World of Crickets
These four activities, use crickets to teach the scientific process to elementary and middle school students. Students will make observations and record data on the types of food that crickets like to eat. In another lab, students determine if crickets respond to light or dark. A “Crickthermometer” activity asks students to design an experiment to find out whether they can predict air temperature by counting the number of times a cricket chirps. In the last activity, “The Musical World of
Object of History
The Object of History is a cooperative project between the Smithsonian’s National Museum of American History and George Mason University’s Center for History and New Media. The project was conceived of in an effort to find a low cost way for students and teacher of U.S. History to have access to the museum’s collections and the expertise of the curators. As a result the materials on the site are designed to improve students’ content knowledge of standard topics in U.S. History and to imp
World History Survey Course on the Web
World History teachers face many challenges to incorporating primary sources in their teaching—the pressures of coverage in survey courses, the lack of available materials, and inadequate training in dealing with unfamiliar sources from a range of cultures. World History Sources responds to these challenges (as well as the new opportunities offered by the Internet) by creating a website to help world history teachers and students locate, analyze, and learn from online primary sources and to fu
Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
Whippo Problem Space
What! You haven't ever seen a Whippo? What about a Whammel? Well, how do you think that whales evolved? Which mammals do you think are their closest living relatives? Trying to make sense of whale evolution is a great place to engage in some evolutionary reasoning and look closely at the way scientists work through difficult historical problems. By the way, the term Whippo is used as a sort of shorthand for the hypothesis that whale and hippos represent sister groups—that is, they are each oth
HIV Problem Space
In this problem space, you will have access to the following materials: background information on HIV/AIDS, the original Markham et al. reference and other primary literature, viral sequences from each visit of each patient, patients' CD4 counts at each visit, phylogenetic trees of the virus sequences from each patient, a phylogenetic tree of each patient's starting consensus viral sequence, a published activity using this data from the book Microbes Count!, and additional materials prepared by
In this exercise you will name triangles.
A Lab on Population Genetics and Evolution: A physical Model and Computer Simulation
This laboratory exercise features a physical and computer simulation of Hardy-Weinberg equilibrium.
What Is It Like to Be a Reporter?
Reporters have to meet a lot of deadlines and spend a lot of late nights, but the profession is rewarding, as well. Learn about the different perks of being a reporter with help from a journalism professor. (01:31)
This nine minute video is about the importance of land and its power. The Feudal System was the "power pyramid" of the Medieval age. The Kings were the ones with Power aka land. People were afraid of the Viking and so they turned to the King for protection in these dangerous times. Students should know what a monarchy is to provide more background to this lecture.
ÉvaTic : une base de connaissances sur l'évaluation des environnements d'apprentissage reposant su
Depuis quelques années, l'apprentissage en ligne a progressé de façon remarquable. Si les pratiques deviennent de plus en plus performantes, la littérature consacrée à l'évaluation demeure fragmentée. Pourtant toute la question de l'évaluation de l'efficacité de ces nouveaux modèles demeure incontournable compte tenu des enjeux stratégiques et des sommes investies. Cet article présente une base de connaissance conçue pour favoriser le partage de pratiques variées. La base de con

"I Will Kill Frick": Emma Goldman Recounts the Attempt to Assassinate the Chairman of the Carnegie S
Henry Clay Frick, chairman of the Carnegie Steel Company, was demonized by labor for his role in the violent Homestead strike in 1892 in which a pitched battle was fought between strikers and company-hired Pinkerton detectives. Known for his uncompromising and cruel tactics, Frick became an obvious target for labor activists looking to make a statement during the protracted strike. In this excerpt from her autobiography, Living my Life, radical Emma Goldman described how fellow radical Alexander

Using Popcorn to Simulate Radioactive Decay
In this activity popping popcorn is used to illustrate the spontaneity, unpredictability, and irreversible change associated with radioactive decay. This site provides notes and tips, a list of teaching materials and methods, and links to related online resources.
'Since you asked..,' with Lucille Clifton
Emmy award-winning poet, Lucille Clifton, answers questions that students might typically ask a poet. The questions are: When did I start writing? When did I know I wanted to be a poet? Where do I get ideas? What do I write with? What is poetry anyway?
