This unit is loaded with phenomena. The real world task of being a member of Oregon's Energy Commission that must create a 50-Year Energy Plan propels students through a learning arc that includes electricity, magnetism, power production, and climate science. After the Request for a 50-Year Energy Plan students jigsaw energy sources and power production. They need to understand the basic physics of how generators works leads us to build and explore motors (starting with speakers which also connect to the Waves & Technology unit) and inefficient generators (electric guitars). The need for large amounts of energy and efficient generators motivates us to engineer wind turbines and optimize solar cells for a local facilities use. Creating the rubric to evaluate large scale power production launches us into climate science. With all the learning of the unit students and many real world constraints student finally complete, compare, and evaluate their 50-Year Energy Plan.

This project allows students to apply concepts of momentum conservation and energy conservation from classical physics. However, here they are not enough: they must be combined with modern physics, using concepts from relativity and particle physics as well as modern units that put energy, mass, and momentum in terms of MeV and GeV. Most important, students will learn about both fundamental and cutting-edge physics by actually doing what physicists do.

Attraction and Repulsion: The Magic of Magnets, Fall 2005
Conditions of Use:
Remix and Share
Rating

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 activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field. Learners use electric currents that are stronger than the field of the Earth to move a compass needle. The assembly is made using a lantern battery, heavy wire, a Tinkertoy㢠set, and poster board and utilizes 4-6 small compasses and 2 electrical lead wires.

Earth's Magnetic Personality Teacher's Guide
Conditions of Use:
Read the Fine Print
Rating

This magnetism teacher’s guide is one of four activity guides—plus a background guide for teachers—that provide students with the opportunity to build on science concepts related to Earth’s magnetism and its changes, as detected by THEMIS magnetometers located in schools across the U.S. The four activity guides have been used in different types of classes, from physical science and physics classes, to geology classes and astronomy classes. The excitement of actually participating in the THEMIS project helps motivate the students to learn challenging physical science concepts.

The background guide for teachers, the THEMIS GEONS Users Guide describes the important role that terrestrial magnetism plays in shaping a number of important Earth systems. It also explains the basic operating principles behind magnetometers—particularly the system you are now in the process of using to investigate magnetic storms at your school.

Earth’s Magnetic Personality is the fourth and final guide, which was developed with the goal that students can work directly with the THEMIS magnetometer data. The guide covers vectors, the x-y-z magnetometer plots, creating a prediction for aurora using the magnetometer data, calculating the total magnetic field strength and observing it over months, and the waves in Earth’s magnetic field excited by large magnetic storms.

Eddy Currents
Conditions of Use:

Rating

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube. Use this activity to illustrate how eddy currents in an electrical conductor create a magnetic field that exerts an opposing force on the falling magnet, which makes it fall at a slower rate. This activity guide also includes demonstration instructions involving two thick, flat pieces of aluminum to illustrate the same principle.
