Designing a Spectroscopy Mission
Students find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, student teams design and build their own spectrographs, researching and designing a ground- or space-based mission using their creation. At project end, teams present their findings to the class, as if they were making an engineering conference presentation. Student must have completed the associated Building a Fancy Spectrograph activity before
Map that Habitat
Historically, sea floor mapping occurred with a more simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of the boat and noting the measurement on the rope when the weight hits the bottom. This activity will replicate the creation of sea floor bathymetry by taking a simplified form of soundings in the classroom.
Binary and Communication Systems
The purpose of this activity is to introduce students to the concept of binary coding as a language and its practical applications in digital and communication systems. This project is intended to give students a deeper appreciation for communication systems and an understanding of how binary symbols are used to transmit information.
Sound Curricular Unit
Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel through different mediums, and are enhanced or mitigated in designed sound environments. Students are introduced to audio engineers who use their expert scientific knowledge to manipulate sound for the production of music and film. They learn how the invention of the
Engineering and the Human Body
The Engineering and the Human Body unit covers the broad spectrum of topics that make-up our very amazing human body. Students are introduced to the space environment and learn the major differences between the environment on Earth and that of outer space. The engineering challenges that arise because of these discrepancies are also discussed. Then, students dive into the different components that make up the human body: muscles, bones and joints, the digestive and circulatory systems, the nervo
Weather Alert
Students discuss the characteristics of storms, including the relationship of weather fronts and storms. Using simple materials, the students develop a model of a simple lightning detection system and analyze their model to determine its effectiveness as a storm warning system for a community.
"The Depression has Changed People's Outlook": The Beuschers Remember the Great Depression in Dubuqu
Before the Great Depression of the 1930's the Beuschers--he was a sixty-two-year-old railroad worker; she was the mother of their eleven children--had been fairly prosperous: they owned their home and had several life-insurance policies serving as savings. But by the time the Works Progress Administration (WPA) interviewed them in 1937, their lives had dramatically changed: the father had lost his railroad job and the mother was taking in sewing. This interview summary, published by the WPA, sho
"We Are Americans!": The Homestead Workers Issue a Declaration of Independence in 1936
Although many historians have emphasized the conservative dimensions of this language of Americanism--the ways that it reinforced rather than challenged the status quo--historian Gary Gerstle shows that it was considerably more complex and contradictory. He argues that it was "flexible enough to express both the social democratic and ethnic communalist visions that inspired political activism among the nation's workers during the Great Depression. As in other communities, this working-class Amer

14.02 Principles of Macroeconomics (MIT)
This course will provide an overview of macroeconomic issues: the determination of output, employment, unemployment, interest rates, and inflation. Monetary and fiscal policies are discussed, as are the public debt and international economic issues. It introduces basic models of macroeconomics and illustrates principles with the experience of the United States and other economies.
