With Engino' s mechanics: pulley drives set learn how pulley drives can be used to transfer force with reduced friction and how they can increase force or speed at amazing levels. Pulleys have been used for thousands of years and are essential parts of complex machines in modern times, solving many technological problems. Build 8 working models such as a material lift, a stationary bike, a crane bridge, a blender, a construction crane and a windmill. You can find easy-to-follow building instructions for all models either online or in the booklet included. The booklet provides detailed explanations of the different scientific principles applied and incorporates innovative experimental activities for hands-on learning. A quiz section is also available to challenge your newly acquired knowledge! conduct thorough experiments and discover - how a compound pulley system works - how to change the direction of motion of a pulley system - how a pulley's size affects force and speed. The Engino building system was invented by Costas Sisamos, a former teacher and engineer for the purpose of helping students build technological models creatively and easily to experiment and learn about science and technology in a way that includes all the benefits of play. Research grants from local and e.U. Sources helped transition the three year research project into an innovative product. Since then Engino has developed more snap-fit components such as gears, pulleys, motots, and solar panels. The major advantage of the Engino system is that it's design flexibility enables children to build simple or complex models quickly using a small number of components. Engino for ages 8 and up.
