Over the past few years, wind power has been among the fastest growing sources of energy in the world. Rather than connecting a battery to the motor to make something move, a wind turbine is connected to the motor, and its movement generates electricity. Math Worksheet (pdf), Scaling Activity: Wind Power! The deliverables of aerodynamic design include recommendations on the number of blades, airfoil selection, chord and pitch distribution, rotor diameter, RPM, etc. Thar She Blows! The idea is to build a horizontal turbine with three blades. Describe how engineers construct a wind turbine. Review their answers to gauge their mastery of the subject. You’ll be able to test the power of your blade designs with the digital multimeter, store wind energy for later use with the super capacitor, and experiment with series and parallel circuits using two motors and three LEDs. Thanks for your feedback! The motor should rest snugly in the coupler but not be pushed all the way in.6. Position your turbine in front of a box fan so that the wind turns the blades; this will generate electricity.2. Have students attach these new blades to the motor and adjust them at various angles to produce the greatest voltage. Thanks for your feedback! • KidWind Basic Turbine Building Parts kit(includes DC motor with wires, 12-hole crimping hub, and 25 dowels) Energy can be transferred in various ways and between objects. If the wind speed doubles, the power available to a wind turbine increases by a factor of eight. This exploratory project teaches engineering and modeling and—to make it age- and skill-appropriate—can be scaled up or down in complexity to create more or less electricity, as well as to demonstrate concepts such as energy transformation and blade efficiencies. 1. 3 - This project (Design of Aeroleaf Wind Turbine) is about designing and manufacturing a Vertical Axis Wind Turbines VAWT to transfer the wind speed to a rotational motion using these turbines. for our small-scale wind turbine. Measurement, Physical Science, Science and Technology. It is the sum of an object's kinetic and potential energy. Tape the motor to a ruler to serve as a handle. Have team members work together to complete the worksheet. Any reusable equipment that is necessary to teach the activity is not included in this estimate; see the Materials List/Supplies for details. Inside the turbine is an electric generator, which is a rotating machine that supplies an electrical output with voltage and current. The wind turbine will generate enough alternating current, or AC, to power a small light bulb. A roller coaster at the top of a hill has potential energy. Renewable energy is the wind beneath our turbine blades. (Grades Have students share and compare their designs by giving brief engineering reports to the class. Where could an engineer place the wind turbine? Use of the TeachEngineering digital library and this website constitutes acceptance of our Terms of Use and Privacy Policy. This increased airflow (wind) can be equivocated to wind turbine generators. Alignment agreement: 4), 2 pieces of thin electrical wire with alligator clips, each about 50 cm or 20 inches long, cylindrical-shaped cork, at least 2 cm or ¾ inch in diameter; alternative to cork: Styrofoam ball, 1 or 2 small electric fans or hair dryers. Question/Answer: Ask the students and discuss as a class: Engineer Challenge Question: Ask students to think about the following engineering design problem. www.teachengineering.org/activities/view/cub_energy2_lesson07_activity2, Search curriculum by Common Core standards, Wild Wind! ), A homeowner wants to use a wind turbine to supply electricity for their home, but no hills are near the house. The concept of wind can also produce power in other applications, such as a turbocharger, for example, which is a compressor used in auto or jet internal-combustion engines to increase power output. within type by subtype, then by grade, etc. Popular Mechanics participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our links to retailer sites. PVC 24-inch-long pipe • 20-inch box fan or other wind source Wind as a Renewable Energy Source, Build an Anemometer to Measure Wind Speed, Windmill of Your Mind — Distributed Energy Goes to School, Click to view other curriculum aligned to this Performance Expectation, Scaling Activity: Wind Power! Students learn about wind as a source of renewable energy and explore the advantages and disadvantages wind turbines and wind farms. The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. (Good photographs of the first large utility-scale wind turbine installed on the Rosebud Sioux Indian Reservation) http://www.cleanair-coolplanet.org/action/windbuilders.php, Renewable Energy Lesson Plans. Our wind turbine must produce enough power to provide electricity to people in developing countries who lack this fundamental need. All ideas should be respectfully heard. Describe the transformations of energy that occur in a wind turbine. We may earn commission if you buy from a link. Making Weather Vanes to Find Prevailing Winds, Wind Energy: Making & Testing Pinwheels to Model Wind Turbines. A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine. What factors might engineers consider when deciding where to put a wind turbine generator or a wind farm? 1.0.1 INTRODUCTION Wind … Use the alligator clips to connect to a multimeter to measure the voltage. These turbines will be attached to a manufactured tree that will look like a modern design, which Have them discuss their answers in teams and share their thoughts with the class. Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. Explore the Renewable Energy Living Lab for real wind measurement, energy collections systems and real-world data. Record on the worksheet. Thread the wires attached to the DC motor into the mouth of the coupler, all the way through the 90-degree PVC fitting.5. If time is limited, speed up the activity by bringing in two fans to provide two test stations. Next, attach the crimping hub to the motor by pressing it onto the driveshaft.7. Explore how wind velocity affects the amount of electricity produced by changing fan speeds. In this capstone design project, I am going to design and fabricate the blades of a small homemade wind turbine using plywood and aluminum. Repeat to make the second leg of the base.3. • Hot glue/glue gun Students should never touch any bare or exposed metal in a circuit that is generating electricity.
