This learning cycle features 32 videotaped experiments, organized sequentially for introducing electricity and magnetism. Each video includes learning goal, prior knowledge required, and post-activity questions. Topics include electrostatics, electric charge, conductance, charging by induction, electric field, electromagnetism and induced current, RC circuits, and more. The instructional method is based on cognitive apprenticeship, in which students focus on scientific process by observing, finding patterns, modeling, predicting, testing, and revising. The materials were designed to mirror the activities of scientists when they construct and apply knowledge.

4. The Physical Setting
4G. Forces of Nature
6-8: 4G/M3. Electric currents and magnets can exert a force on each other.
6-8: 4G/M4. Electrical circuits require a complete loop through which an electrical current can pass.
6-8: 4G/M5. A charged object can be charged in one of two ways, which we call either positively charged or negatively charged. Two objects that are charged in the same manner exert a force of repulsion on each other, while oppositely charged objects exert a force of attraction on each other.
9-12: 4G/H2c. Electric forces hold solid and liquid materials together and act between objects when they are in contact—as in sticking or sliding friction.
9-12: 4G/H4ab. In many conducting materials, such as metals, some of the electrons are not firmly held by the nuclei of the atoms that make up the material. In these materials, applied electric forces can cause the electrons to move through the material, producing an electric current. In insulating materials, such as glass, the electrons are held more firmly, making it nearly impossible to produce an electric current in those materials.
9-12: 4G/H5ab. Magnetic forces are very closely related to electric forces and are thought of as different aspects of a single electromagnetic force. Moving electrically charged objects produces magnetic forces and moving magnets produces electric forces.
9-12: 4G/H5c. The interplay of electric and magnetic forces is the basis for many modern technologies, including electric motors, generators, and devices that produce or receive electromagnetic waves.
12. Habits of Mind
12D. Communication Skills
6-8: 12D/M6. Present a brief scientific explanation orally or in writing that includes a claim and the evidence and reasoning that supports the claim.
6-8: 12D/M8. Explain a scientific idea to someone else, checking understanding and responding to questions.
