30-Student Classroom Module
Elementary STEM curriculum at its best
TINKER WITH REAL MOTORS, WOOD, AND HARDWARE
The best-selling Electric Motors Catalyst includes 50+ high-quality parts that are made to last. It’s more than a toy — real hardware and tools help kids connect the parts with the world around them.
GET STARTED WITH INSPIRATIONAL CHALLENGES
There’s no limit to what kids can invent with the Catalyst, but a deck of 10 cards ignites the imagination with challenges like “Build a machine that can scramble an egg.”
ENGAGE IN STEM LEARNING
The Catalyst gives kids an intuitive sense for STEM principles from electric circuits to forces and friction. Teachers: check out our guide to Next Generation Science Standards connections
CREATE ENDLESS DESIGNS WITH 100% REUSABLE PARTS
The Electric Motors Catalyst is not a one-time activity or a single project—it’s meant to be made and unmade and remade in as many ways as kids can imagine.

“Unique gift idea for the kid who has everything.”
“Imagine never having to set foot in a toy store again — or at least for a few months.”
“Do we spot an engineer-in-training?”
“This was so fun and definitely worth the price.”
This is an amazing kit that will create hours of enjoyment for you and your child… My son and I have literally spent over 100 hours playing with and building with this kit. There are challenges you can try to build, but he has the most fun just creating his own ideas. We are so impressed that we are buying multiple sets for my wife’s classroom.

I purchased this kit for my son and daughter last year. I was pleasantly surprised to find that my daughter enjoys it even more than my son. I often find her in room building and tinkering by herself or even showing her younger sister how to build things. This is a fantastic and super educational toy.
