OWI Inc Kinetic Racer, STEM STEAM Science Project Gift for Kids Ages 8 and Up Partes de Word. 14 piece do it yourself kit (assembly required) Requires zero batteries! Powered by Hand Crank Generator. Perfect tool to teach sustainable energy, while also providing sustainable fun Ages 8 and Up Create and store energy with OWIs Kinetic Racer. This 14 piece kit requires zero batteries, and is the perfect tool to teach sustainable energy, while also providing sustainable fun! Boys and Girls ages eight and up will be able to experiment with a pre assembled hand crank generator and demonstrate how kinetic energy is converted into electrical energy. Detailed lesson plans, with the use of the generator, light emitting diode (LED), and Miniature Bulb, will have children amazed as they witness the energy they generated, illuminate almost magically. Once the energy conversion principle is established, knowledge hungry students will connect the hand power generator to the Kinetic Racer with a capacitor and experiment on how energy can be stored and discharged. Scholarly children will be able to test preconceived hypotheses on how much energy is stored with 30 turns, 60 turns, even 100 turns of the hand powered generator! This trial and error based learning will free up the minds of children and allow them to discover and explore physics and math without the fear of failure. The Kinetic Racer is much more than a hands on training tool. The instruction manual includes a full curriculum, complete with test questions, answers, and fun activities to extend the play value of the Kinetic Racer. Producing energy, storing energy, and using energy without the use of batteries makes for a great science and learning kit.
