Inquiry-based lessons challenge young learners as they build, investigate, problem-solve, discuss, and evaluate scientific and design principles in action.

This experiment guide aligns with the national STEM standards and is designed for grades 5‒9. Students will learn about the relationships between time, distance, speed, and more!
- PROMOTES TEAMWORK – This educational engineering set is more fun when constructed with friends. One to three kids can put their heads together and figure out the structure, exchanging ideas as they tinker with the bits and parts, and solving the model faster through teamwork. They’ll build camaraderie and develop social skills as they play.
- STEAMagination: It’s the connection of STEAM (science, technology, engineering, arts & math) with a child’s natural curiosity and creativity and it powers the fun of each and every K’NEX building set.
