ELECTRICITY, MOTORS & GENERATORS, CONTINUEDBuild a Simple AC Generator—Classroom SetDemonstrate the fundamental principles of generators by converting spinning mechan-ical energy into electrical energy that lights an LED. In this simple device, two powerful neodymium magnets spin in a coil of wire to induce a current and show Faraday’s Law. Also use the device to show the difference between direct and alternating current. Includes instruc-tions and student worksheet. Classroom Set has materials for eight student groups. AP7276 I $135.40Motor Set, BasicThere is no better way to understand how an electric motor works than to build one yourself! Students begin by constructing their own motor parts, such as the armature, commutator and brushes. They then assemble the motor parts, hook up the power and watch their motor run. An activity your students will never forget. All parts are included, and easy-to-follow step-by-step instructions are provided. AA battery required and available separately. AP4635 I $10.55Build a Simple Motor—Flinn STEM Design Challenge™Students build a simple spinning motor with a magnet, copper wire and 9-V battery then experiment with various designs to construct the fastest spinning motor. Hands-on activity introduces how electricity and magnetism work to generate power. Includes detailed Teacher Notes, reproducible student hand-outs and all necessary equipment. Super Value Kit is complete for 30 students working in pairs. All materials are reusable.AP7936 I $54.95DC Motor Made Simple—Super Value Laboratory KitChallenge students to build a simple motor with only a battery, copper wire and a strong magnet! In this design challenge, students recreate a simple model of Michael Faraday’s 1821 device that produced “electromagnetic rotation.” Once success is achieved, students combine science and art to design and build a more creative motor. Includes magnets, batteries and copper wire. Students supply additional materials for their creations. AP6263 I $32.05Build a Dry Cell Battery—Student Laboratory KitStudents build a simple dry cell battery from aluminum and air then investigate its elec-trical properties. Extensions include battery modifications to improve performance and connecting batteries in series and parallel to measure changes in voltage and current to learn about electric circuits. Concepts include electrodes, oxidation–reduction reactions, voltaic cells, electric circuits, voltage and current. Includes complete instructions. AP6925 I $78.80Introducing STEM through Electricity—Flinn STEM Design Challenge™Students make a simple electric circuit and draw circuit diagrams, they then apply their series and parallel circuit knowledge to wire a duplex outlet with two lamps in which a switch controls one lamp but not the other. Success at each step encourages students to continue the design process at the next level. You will see the “lightbulbs go on” as students engage in science and engineering practices to master a final circuit design challenge. AP8318 I $49.95
