This system provides you with all the answers you need concerning the basics of using wind energy. With the help of curriculum-based trials, it discusses different topics which are necessary for understanding the functions of wind power plants. The study of how wind speed, wind direction or rotor type influences the power output are only some examples of possible experiments. Both qualitative experiments for students from age of 11 to 13, and complete quantitative trials for physics lessons until the age of 19 are described in detail. For the qualitative trials, the expansion "Measurements without Measuring Tools" is required.
Experiments:
Dependence of the wind power plant on wind speed:
Hands-on experience with light bulb (only with the expansion "Measurements without Measuring Tools") By measuring the voltage at the generator By determining the power output of the generator using a constant resistance (For the quantitative determination of the wind speed, the expansion ?wind speedometer? is required. Otherwise the wind speed can only be determined using given calibration curves) Variation of the generated voltage produced by changing the load: With resistance With the load?s buzzer, engine and light bulb (only with the expansion "Measurements without Measuring Tools") Analysis of wind speed in front of and behind the rotor (only possible with the expansion: Wind Speedometer) While idle With the load generator Effincency determination of a wind power plant Saving energy Energy conversion and use of wind energy: Studying the conversion of energy kinetic energy rotational Energy electrical energy radiation energy by the LED Studying different energy conversions with the buzzer, engine and Light bulb (only with the expansion "Measurements without Measuring Tools" Analysis of different rotor types Comparison with the 3-bladed and Savonius rotor Comparison with 2-, 3-, and 4-bladed rotors Qualitative comparison using a light bulb (only with expansion "Measurements without Measuring Tools") Characteristics of the wind generator Dependence of the wind generator on wind direction While engine is idle (measurement of voltage) Loaded Qualitative experiments using a light bulb (only with expansion "Measurements without Measuring Tools") Other application tests These additional, interesting experiments are included in the curricula but only have an indirect correlation to the subject of wind energy: Air resistance of different objects RPM Measurement of the wind generator
