Engino for ages 8 and up. Engino - discovering STEM: physics laws - inertia, friction, circular motion & energy conservation - brings complex designs into simple focus with 13 pages of clear, 3-D rendered, instructions with more models illustrated online at Engino' s website or using the Engino 3D app downloadable free for Android or Apple iOS. The manual also includes 12 pages of theory and facts, a 2 page quiz, 4 pages of experimental activities illustrating physics concepts. Understand the basic laws of physics and mechanics that govern our world. Build 6 working experimental assemblies such as a inertia test platform, sharpening wheel, rocket launcher, rubber band car. or add some imagination and make something new. - the Engino building system was invented by Costas sesames, 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 eruv. 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, motors, 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.
