Thames & Kosmos Structural Engineering: Bridges & Skyscrapers | Science & Engineering Kit | Build 20 Models | Learn about Force, Load, Compression, Tension | Parents' Choice Gold Award Winner, Blue
Do you ever wonder how bridges span huge distances and how skyscrapers stay standing? Structural engineers use physics and their knowledge of the properties of building materials and geometric shapes to design structures with sufficient strength and stability. With this kit of modular building pieces, you can learn the basics of structural engineering by conducting a series of 20 model-building experiments. Each model demonstrates a basic principle of mechanical physics or structural engineering in a hands-on way. Start out with small models that demonstrate how structural elements can be attached together to maximize the strength of a structure for a fixed amount of material used. Learn about basic structural elements including columns, beams, trusses, plates, arches, shells, and catenary. Explore the forces acting on structural components including tension, compression, shear, and bending. Move onto building more complex models of trusses, roofs, and small buildings. Experiment with different types of bridge construction: a truss bridge, arch bridge, cantilever bridge, rope bridge, and suspension bridge. Finally, build models of towering skyscrapers. What is the tallest tower you can build using only the pieces included in the kit? Learn about the strength and stiffness of materials. See how structural engineers optimize factors to maximize safety, and minimize cost and the risk of structural failure. A 36-page, full-color manual guides you through model building with step-by-step illustrated instructions.

Thames & Kosmos Motors & Generators Multi, 8.9
Electric motors and generators are in countless devices, appliances, and vehicles we use every day. They are an essential technology in our modern world. With this kit, you can conduct 25 experiments to learn how an electric motor converts electricity into motion, and how an electric generator does just the opposite, converting motion into electricity. The electric motor is made of transparent plastic to show how the inside components work. Set up the motor to run on battery power and learn how a motor works. Then reconfigure the device to work in reverse as a hand-crank electric generator. Experiment with magnets to learn about the force of magnetism, and how magnetic fields relate to electric current. Build simple circuits consisting of the motor or generator, wires, and a light bulb to learn about the flow of electricity. Learn about gears and drive-trains and how they work to effectively convert kinetic energy into electrical energy and back again. The full-color, 48-page manual guides your experiments with step-by-step instructions.
