Audio and Speaker Electronics
Take a hands-on ride through the fundamentals of electronics and acoustics, and the process of loudspeaker design and construction. Learn about the engineering and art involved throughout music/movie recording and playback, the design and application of everything from microphones to DACs, amplifiers, and speakers. With the aid of computer assisted audio measuring equipment at the MIT Edgerton Center, analyze the frequency response and distortion of speaker drivers, and understand their effect o
Children Between Two Nations
The belligerent anti-immigrationism of recently-retired CNN television and radio commentator Lou Dobbs has become so much of a trademark in U.S. popular culture that reviewer after reviewer of the 2008 Patricia Riggen film La misma luna (Under the Same Moon) has used his name as a shorthand reference to tell their readers what to expect from the movie: Lou Dobbs, grab your hankie
Winter Math Activities
There are many possibilities for winter math data collection activities. Look for opportunities to have students create tally charts, clothespin graphs, Venn diagrams, bar and line graphs to organize data and analyze the results of the data collection. Build on students' natural fascination with penguins by including these math pattern activities. The Koch Snowflake is an example of an iterative drawing as each successive stage begins with the previous stage. The Koch snowflake begins with an eq
Constructing a 90 degree angle with compass and straightedge
An interactive applet and associated web page that show how to construct a 90 degrees right angle with a compass and straightedge. The animation can be single-stepped or run as a continuous movie. 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.
Theodore Roosevelt: His Life and Times on Film
Theodore Roosevelt was the first U.S. president to have his career and life chronicled on a large scale by motion picture companies (even though his predecessors, Grover Cleveland and William McKinley, were the first to be filmed). This presentation features 104 films which record events in Roosevelt's life from the Spanish-American War in 1898 to his death in 1919; 8 of these films have previously appeared in other American Memory presentations. The majority of films (87) are from the Theodore
Small-Town America, 1850-1920
This site presents 12,000 photographs of New York, New Jersey, and Connecticut from the 1850s to the 1910s from a collection at the New York Public Library. The views show natural landscapes as well as buildings and street scenes in cities, towns, and villages. They also depict agriculture, industry, transportation, homes, businesses, local celebrations, natural disasters, people, and costumes.
The workshop is intended for Doctoral students in the health and social sciences who are at the stage of developing a research proposal. Participants will gain skills in the design of conceptually cogent and methodologically rigorous dissertation proposals. The Workshop has an emphasis on topics that relate to Africa, but can be applied to a broad range of research issues.
Concepts in Economic Evaluation
Describes how economic theory is linked to economic evaluation techniques like cost-benefit and cost-effectiveness analysis and to introduce students to many concepts that are specific to economic evaluation. Introduces students to the many varieties of economic evaluation to establish a common terminology. Discusses cost-benefit with a demonstration of how this type of evaluation is most clearly linked to economic theory. Explores other theories and concepts, including cost measurement, benefit
Conflict resolution: Raising an issue
The way we raise an issue has a significant effect on the entire problem-solving process. By raising an issue in a constructive way, we set the stage early for resolving the conflict productively. The purpose of this unit is to give participants an opportunity to practice and explore this type of problem solving.
Elementary GLOBE: Earth System Play
The class will brainstorm, write, create, and produce a play in which they represent how all the Earth systems are interconnected. This play can be based on the Elementary GLOBE book "All About Earth: Our World on Stage" or on other student-generated topics representing interconnections of the Earth systems. The purpose of the play is to serve as a performance assessment providing students with the opportunity to display what they have learned about the Earth as a system in a creative manner. Th
Elementary GLOBE: We're All Connected
A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. One of the "big ideas" in Earth system science is the notion of interaction among parts of the Earth system. In the Elementary GLOBE book All About Earth: Our World on Stage, the children in Ms. Patel's class discuss instances of how the four major spheres of Earth's system interact. They symbolize these interactions by using large arrows to link the system components: air, water, soil, living
Elementary GLOBE: Earth System in a Bottle
A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class
From Godzilla to the Ring: An Overview of Japanese Film
The unit is a gentle, eclectic introduction to Japanese film. It also draws some comparisons between US films and Japanese films. Students examine US and Japanese film from multiple perspectives. The unit features readings, presentations, and interactive activities. For the culminating project, each student creates a simple website on a Japanese movie that he or she has chosen to watch.
Radiology Lab 2: Cardiovascular
Introduction to concepts important in cardiovascular imaging of normal anatomy, including angiographic techniques and cross-sectional methods.
Active Transport in Insect Malpighian Tubules
The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own exper
A Novel Method to Archive Plant Material for DNA Analysis
In this exercise, students isolate and analyze DNA from food plants in a supermarket, or from common backyard plants. Extracting plant DNA is often difficult using conventional means because undesirable material including PCR inhibitors often co-purifies with the DNA. The novel approach used in this exercise is simple and quick, and also avoids the use of dangerous organic reagents. Students crush plant material (spinach leaves in this exercise) onto special cards originally used to archive bloo
Virtual Maths - Numbers, Geometry 3D shapes

Practicing Elaboration in a Problem/Solution Essay
One theory suggests that students tend to list in an essay because they lack the tools to elaborate. Because they do not have the strategies, they attempt to fill up the empty space by introducing new primary ideas instead of fleshing out the ideas they have already presented. This activity attempts to make students aware of the need to elaborate and to provide students with some workable strategies for elaborating. Using a PowerPoint presentation, the teacher demonstrates the necessity for elab
Developing continuous air during articulation
Combining long tones and burst-tonguing will assist many beginning instrument players to eliminate excessive breaths while articulating.
"It Was Considered Low Music": Pianist Eubie Blake on the Birth of Ragtime at the Turn of the Centur
Ragtime music, with its syncopated, polyrhythmic style, was born, according to cultural historian Robert Snyder, in the 1890s in the black saloons and brothels of southern and Midwestern cities like Baltimore and St. Louis. By the end of the 19th century ragtime had assumed a place at the center of American popular music and remained there until the 1920s. Ragtime meant a tinkling piano and no one played the ragtime piano any better or longer than Eubie Blake, born in Baltimore in 1887. In this
