Build fully-functioning replicas of real-world machines alone or with friends and mix and match the components of the K'NEX Education Building Simple Machines Class Set! Suitable for students ages 8 and up, this innovative set challenges students as they build, investigate, problem solve and evaluate scientific and design principles in action. Students from grade levels 3 to 5 will benefit from its complex yet easy-to-understand layout, challenging their minds and hands. In a classroom setting, the set can be constructed by 16 to 24 students working as a team, which also promotes social skills and collaboration.This Simple Machines set can be used to build 15 fully-functioning replicas of real-world machines. Each set includes 2,176 parts and pieces kept in a convenient storage bin with a snap-on lid. Up to 8 models can be made at a time. The machines that can be created include a first class level balance, an elevator with fixed and movable pulleys, and a crank fan with gears and spur gears. The package includes building instructions for children's comprehension and an extensive Teacher's Guide that is aligned to national educational standards, including ITEEA, NSES, NCTM, NGSS, and Common Core. This engrossing set promotes STEAM (science, technology, engineering, arts, and math) concepts and encourages children's natural curiosity and creativity, setting them on the path toward a fundamental understanding of STEAM/STEM subjects. Aside from its STEM-compatibility, the Simple Machines set also encourage critical thinking, exploratory learning, problem-solving, discovery, scientific inquiry, investigation, and experimentation. With this set, kids will be able to build, investigate, find solutions, and reflect on their work once they're finished.
