Students use a simple set up consisting of a current carrying wire and a magnet to explore the forces which enable biomedical imaging. In doing so, students run a current through a wire and then hold magnets in various positions to establish and explore the magnetic force acting on the wire. They move the magnets and change the current in the wire to explore how the force changes.

Through a series of three lessons, each with its own hands-on activity, students are introduced to 1) forces, loads and stress, 2) tensile loads and failure, and 3) torsion on structures—fundamental physics concepts that are critical to understanding the built world. The associated activities engage students through experimenting with hot glue gun sticks to experience tension, compression and torsion; the design of plastic chair webbing strips; and problem-solving to reinforce foam insulation "antenna towers" to withstand specified bending and twisting.

The goal of this lesson is to assist students to relate the forces acting upon particular objects and the “unseen” resolution of those forces. The video begins with a story line involving Adam, who helps his father in the garden by disposing of a garbage bag of leaves—the very act that involves resolution of forces. This lesson includes embedded video clips, animations, diagrams and inquiry-based experiments where students are required to work collaboratively and answer thought-provoking questions. The experiments will involve the study of the resolution of forces on objects placed on varying planes or on platforms of different angles, using materials that are easily found. Finally, students are required to discuss and apply what they have learned to determine whether it is easier to push or to pull a luggage bag with wheels. The lesson will take about 50 minutes to complete.

Use this activity to explore forces acting on objects, practice graphing experimental data, and introduce the algebra concepts of slope and intercept of a line. A wooden 2 x 4 beam is set on top of two scales. Students learn how to conduct an experiment by applying loads at different locations along the beam, recording the exact position of the applied load and the reaction forces measured by the scales at each end of the beam. In addition, students analyze the experiment data with the use of a chart and a table, and model/graph linear equations to describe relationships between independent and dependent variables.

The FLLITE website contains a collection of lessons in second language literacy for various languages.

The website is the focal point of the FLLITE Project, which takes the creative moments found in everyday language use as the basis for lessons in second language literacy. By emphasizing language play as central to communication, FLLITE lessons aim to develop language awareness as well as communicative abilities through the integration of speaking, reading, listening, and writing tasks.

The goal of the FLLITE Project is the publication of classroom-tested lessons based on authentic texts in different languages, for example, blogs, Internet memes, YouTube videos, slam poetry, and so forth.

All FLLITE lessons carry an open license that allows you the teacher to…

…access, adapt, and re-use any lesson; and
…contribute a lesson for editorial feedback and publication.

What do collapsed buildings, infected hospital patients, and crashed airplanes have in common? If you know the causes of these events and conditions, they can all be prevented.

In this course, you will learn how to use the TU Delft mind-set to investigate the causes of such events so you can prevent them in the future.

When, for instance, hundreds of hospital patients worldwide got infected after having gall bladder treatments, forensic engineering helped reveal how the design and use of the medical instruments could cause such widespread infections. As a result, changes were made to the instrument design and the procedural protocols in hospitals. Learning from failure in this case benefitted patient health and safety across the world.

After taking this course you will have an understanding of failures and the investigation processes used to find their causes. You will learn how to apply lessons gained from investigating previous failures into new designs and procedures.

Inspired by the work of the architect Antoni Gaudi, this research workshop will explore three-dimensional problems in the static equilibrium of structural systems. Through an interdisciplinary collaboration between computer science and architecture, we will develop design tools for determining the form of three-dimensional structural systems under a variety of loads. The goal of the workshop is to develop real-time design and analysis tools which will be useful to architects and engineers in the form-finding of efficient three-dimensional structural systems.

Derek Turner, Professor of Philosophy, has written an introductory logic textbook that students at Connecticut College, or anywhere, can access for free. The book differs from other standard logic textbooks in its reliance on fun, low-stakes examples involving dinosaurs, a dog and his friends, etc.

Students learn about four forms of equations: direct variation, slope-intercept form, standard form and point-slope form. They graph and complete problem sets for each, converting from one form of equation to another, and learning the benefits and uses of each.

How and why do we participate in public life? How do we get drawn into community and political affairs? In this course we examine the associations and networks that connect us to one another and structure our social and political interactions. Readings are drawn from a growing body of research suggesting that the social networks, community norms, and associational activities represented by the concepts of civil society and social capital can have important effects on the functioning of democracy, stability and change in political regimes, the capacity of states to carry out their objectives, and international politics.

Major narrative texts from diverse Western cultures, beginning with Homer and concluding with at least one film. Emphasis on literary and cultural issues: on the artistic significance of the chosen texts and on their identity as anthropological artifacts whose conventions and assumptions are rooted in particular times, places, and technologies. Syllabus varies, but always includes a sampling of popular culture (folk tales, ballads) as well as some landmark narratives such as the Iliad or the Odyssey, Don Quixote, Anna Karenina, Ulysses, and a classic film. This class will investigate the ways in which the formal aspects of Western storytelling in various media have shaped both fantasies and perceptions, making certain understandings of experience possible through the selection, arrangement, and processing of narrative material. Surveying the field chronologically across the major narrative genres and sub-genres from Homeric epic through the novel and across media to include live performance, film, and video games, we will be examining the ways in which new ideologies and psychological insights become available through the development of various narrative techniques and new technologies. Emphasis will be placed on the generic conventions of story-telling as well as on literary and cultural issues, the role of media and modes of transmission, the artistic significance of the chosen texts and their identity as anthropological artifacts whose conventions and assumptions are rooted in particular times, places, and technologies. Authors will include: Homer, Sophocles, Herodotus, Christian evangelists, Marie de France, Cervantes, La Clos, Poe, Lang, Cocteau, Disney-Pixar, and Maxis-Electronic Arts, with theoretical readings in Propp, Bakhtin, Girard, Freud, and Marx.

This task contrasts the usefulness of four equivalent expressions. Students first have to confirm that the given expressions for the radioactive substance are equivalent. Then they have to explain the significance of each expression in the context of the situation.

Students take a closer look at cars and learn about some characteristics that affect their energy efficiency, including rolling resistance and the aerodynamics of shape and size. They come to see how vehicles are one example of a product in which engineers are making changes and improvements to gain greater efficiency and thus require less energy to operate.

Students model and design the sound environment for a room. They analyze the sound performance of different materials that represent wallpaper, thick curtains, and sound-absorbing panels. Then, referring to the results of their analysis, they design another room based on certain specifications, and test their designs.
