Build it. Race it. Understand the physics behind it.
The Car Build Bundle pairs our rubber-band-powered car kit with a fully self-guided online class. Students engineer their own car from scratch, race it, and then learn exactly why it moves the way it does — kinetic energy, potential energy, friction, and wheel-axle mechanics explained in plain language.
What's included:
Car Build Engineering Kit — craft sticks, bottle caps, rubber bands, skewer axles, and more
Self-Guided Online Class — build guide, physics reveal, and race challenge
Student Workbook — data recording and engineering journal pages
90-day access — work at your own pace
The science: Kinetic and potential energy, friction, wheel-axle mechanics — the physics of every vehicle ever built.
Best for: Grades 2–8 | Ages 7–14 | Competitive learners who love to build and race
Kit ships within 2–3 business days. Class access delivered by email within 24 hours.
