The Zip Line Rockets STEM Boost Kit is a hands-on force-and-motion kit for one middle school student. Learners build and test zip line rockets to explore thrust, friction, and Newton's laws of motion using bilingual student guides (English and Spanish) and included supplies. Students design rockets, string up a zip line, and test different configurations to see which travels farthest and fastest—connecting hands-on experimentation with physics principles. All supplies are included—no additional materials or technology required. Works in classrooms, makerspaces, afterschool programs, camps, and home learning environments.
