This Freshman Advising Seminar surveys the many applications of magnets and magnetism. To the Chinese and Greeks of ancient times, the attractive and repulsive forces between magnets must have seemed magical indeed. Through the ages, miraculous curative powers have been attributed to magnets, and magnets have been used by illusionists to produce "magical" effects. Magnets guided ships in the Age of Exploration and generated the electrical industry in the 19th century. Today they store information and entertainment on disks and tapes, and produce sound in speakers, images on TV screens, rotation in motors, and levitation in high-speed trains. Students visit various MIT projects related to magnets (including superconducting electromagnets) and read about and discuss the history, legends, pseudoscience, science, and technology of types of magnets, including applications in medicine. Several short written reports and at least one oral presentation will be required of each participant.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.

This is a lesson which gives students the opportunity to imagine they are scientists, provides them with a basic understanding of aurora and helps them to use creative methods in their observations. First, students will study the scientific aspect of the aurora. They will also look at images of the aurora (both pictures and illustrations) and describe what they think of when they see them. These descriptions can be stored in the student portfolios as they will be useful in future lessons. Includes teacher notes and instructions, student workshops and an online, animated story, and related teacher resources on aurora. This is lesson three of a collection of five activities that can be used individually or as a sequence; concludes with a KWL (Know/Want-to-know/Learned) assessment activity.

In this lesson, students will demonstrate their understanding of the aurora by writing their own poems. Teachers can decide which form(s) of poetry to use from their worksheets or allow students to create their own. Examples of styles include: Acrostic, List, Haiku, Like and As, and May and Could. To help students get inspired, the class will read a poem on the aurora, and they can also look through their portfolios to help form ideas. Includes teacher notes and instructions, student workshops and an online, animated story, and related teacher resources on aurora. This is lesson five of a collection of five activities that can be used individually or as a sequence; concludes with a KWL (Know/Want-to-know/Learned) assessment activity.

College Physics is organized such that topics are introduced conceptually with a steady progression to precise definitions and analytical applications. The analytical aspect (problem solving) is tied back to the conceptual before moving on to another topic. Each introductory chapter, for example, opens with an engaging photograph relevant to the subject of the chapter and interesting applications that are easy for most students to visualize.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"A new addition to the International Space Station marks the beginning of exciting new explorations of exotic matter. This is BECCAL, the Bose-Einstein Condensate and Cold Atom Laboratory. A joint venture between NASA and the German Aerospace Center, BECCAL will enable scientists across the globe to eliminate one pesky force that plagues earthbound experiments: gravity. A Bose-Einstein condensate is a state of matter formed by cooling a gas of extremely low density to just above absolute zero. Systems like this enable scientists to study aspects of quantum mechanics on a relatively big scale, and could hold the key to bridging quantum mechanics to general relativity. Methods for generating Bose-Einstein condensates vary according to how they trap atoms, using either optics or magnets to do the trick. But typical experiments are hampered by the force of gravity. In a standard setup, gravity deforms optical and magnetic traps..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum cleaner. The site provides an explanation of what happens, asks questions about the activity, and also describes applications to flight. This activity is part of Exploratorium's Science Snacks series.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it. Learners discover it is easier to balance a wooden dowel on the tip of their fingers when a lump of clay is near the top of the stick. Use this activity to introduce learners to rotational inertia.

David explains how a mass can have angular momentum even if it is traveling along a straight line. Then David shows how to solve the conservation of angular momentum problem where a ball hits a rod which can rotate. Created by David SantoPietro.

The simulation shows a ballistics cart. If the cart is at rest on a horizontal surface, it will shoot a ball straight up in the air, and catch the ball again. What if, as in this simulation, the cart is traveling at a constant velocity horizontally, instead? Will the ball land ahead of the cart, in the cart, or behind the cart? Note that the cart fires the ball straight up, with respect to the cart, when the middle of the cart passes the small vertical trigger on the track. Use the buttons to select the different modes (whether there is a tunnel or not, and whether to show the velocity vectors).

This activity enables students to apply concepts of 'newton's laws of motion' that are learned in class to a realworld situation by having them create a car powered by a deflating balloon that travels as far as possible.
