The KNEX Education Building Simple Machines Class set is designed to introduce students in grades 3-5 to the scientific concepts associated with simple machines - Levers, Pulleys, Wheel & Axles, Inclined Planes, including Wedge and Screw and Gears. Students are provided with the opportunity to acquire skills using a hands-on, cooperative, inquiry based approach to information and concepts. This KNEX Education Set includes 2,176 KNEX parts, building instructions, and a comprehensive Teachers Guide, all packaged in a strong plastic tray with a snap-on lid for easy classroom storage. Theres enough parts to build 15 fully-functioning simple machines models, up to 8 at a time, and it supports 16-24 students working in teams. The Teachers Guide provides the information and resources needed to build students understanding of scientific concepts and channel their inquiries into active and meaningful learning experiences. This set is aligned to STEM standards. STEM Education focuses on science, technology, engineering and mathematics concepts taught through problem-solving, discovery, exploratory learning and critical thinking. STEM Education requires students to be active participants in the learning process. KNEX models offer hands-on opportunities that encourage scientific inquiry, investigation and experimentation. Our inquiry-based lessons challenge students as they build, investigate, problem solve, discuss, and evaluate scientific and design principles in action.
