Physics "Seeing" Alernating Current   Alternating current     Subject Electricity Level Upper secondary Language English Type Experiment, exercise, homework       Learning objective   While performing a simple experiment the students get introduced to the nature of alternating current. Teacher and students determine the depth of physical background theory that they want to understand together.     Didactical comments   With the help of a bycicle and a fluorescent tube the students can perfome an experiment outdoors or at home which will help them understand "alternating current". This way they can experience the nature of a complex phenomena themselves.     Suggestions for methodology   This topic can be taught as a single subject in a physics course and is well-suited for self-study as a homework.     Contact details   Name Albert Bramon Email abramon@pie.xtec.es       Last update: 18 June 2007 More Physics Teaching Ideas  •  A Boomerang Project (http://www.esa.int/SPECIALS/Science_on_Stage/SEMLVJC4VUE_0.html)  •  A Merry-go-round as Alternative to the Wind Tunnel (http://www.esa.int/SPECIALS/Science_on_Stage/SEMWO8ANMUE_0.html)  •  Electrodynamic Levitation and Travelling Magnetic Wave (http://www.esa.int/SPECIALS/Science_on_Stage/SEMFA58OY2F_0.html)  •  You Can Do It (http://www.esa.int/SPECIALS/Science_on_Stage/SEMRE58OY2F_0.html)  •  Irish Teaching Ideas Booklets from POS2 and POS3 (http://www.esa.int/SPECIALS/Science_on_Stage/SEMTO58OY2F_0.html)  •  A Bottle of Water with a Sachet of Mayonnaise (http://www.esa.int/SPECIALS/Science_on_Stage/SEMJ468OY2F_0.html)  •  Handling the Canter of Mass (http://www.esa.int/SPECIALS/Science_on_Stage/SEMQ968OY2F_0.html)  •  Reflection Study (http://www.esa.int/SPECIALS/Science_on_Stage/SEMCO78OY2F_0.html)  •  Testing UV Absorption Effectiveness of Sun Screen (http://www.esa.int/SPECIALS/Science_on_Stage/SEMM888OY2F_0.html)  •  E=mc2 (http://www.esa.int/SPECIALS/Science_on_Stage/SEM3G88OY2F_0.html)  •  The Magic Castle (http://www.esa.int/SPECIALS/Science_on_Stage/SEMBZ88OY2F_0.html)  •  Let’s prove the 4th Maxwell Equation (http://www.esa.int/SPECIALS/Science_on_Stage/SEM3898OY2F_0.html)  •  Leonardo's Anemometer (http://www.esa.int/SPECIALS/Science_on_Stage/SEMND98OY2F_0.html)  •  The Physics Teacher (http://www.esa.int/SPECIALS/Science_on_Stage/SEMH4H8OY2F_0.html) Download  •  Alternating current PDF (http://esamultimedia.esa.int/docs/scienceonstage/Alternating_current_POS2.pdf)
