Hands-On Learning! The K'NEX® Education Exploring Machines set is designed to expand upon middle school student's knowledge of simple machines concepts. Students investigate, explore and experiment with the K'NEX® simple machine models as they analyze, synthesize, and evaluate information. The Teacher's guide includes Student Inquiry Sheets and Worksheets for the models highlighted. Student Worksheets ask questions about the machine being investigated and present challenges that can be used to help students think more deeply about the concepts involved. Set includes 1432 K'NEX® parts – enough to build 30 fully-functioning replicas of real-world machines, up to four at a time! Supports 8-12 students working in teams. Grades 5 - 9. Building instructions and comprehensive teacher's guide aligned to Science, Technology, Engineering and Math Standards included. Packaged in a strong storage tray with snap-on lid. 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. K'NEX® models offer hands-on learning 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. Aligned to Science, Technology, Engineering, and Math standards.
