Your child can explore STEM concepts while building a working roller coaster with K'NEX Education STEM Explorations Roller Coaster Building Set! The set will engage and energize middle-school children as they boost their understanding of the STEAM (science, technology, engineering, art, and math) concepts associated with a real-life amusement park ride. This K'NEX Education Set includes over 500 parts, plus a battery-powered motor, allowing a single child or a team of two to three children to build a working roller coaster. Two additional models are also included in this set - a ramp and a half-pipe -which can be built one at a time. The set requires two AA batteries, which are not included. K'NEX Education models offer proactive opportunities for children to develop scientific inquiry, investigation, and experimentation skills. Our inquiry-based lessons challenge aspiring students as they build, investigate, problem-solve, discuss, and evaluate scientific and design principles in action. All K'NEX Education sets come with either a comprehensive guide for teachers or an experiment guide for student-led learning. All lesson plans and experiment guides are written by expert educators and feature hands-on, inquiry-based projects that engage students in today's busy classroom. K'NEX Education sets allow students to build replicas of real-world machines and other models, and through the lesson plans and experiments, to gain a concrete understanding of the principles that make them work.
