2026 Third-Grade Curriculum Kit
GraviTrax Academy
GraviTrax Academy combines marble-run engineering, logic challenges, and hands-on physics in one expansive construction set. With more than 140 pieces and 18 unique action elements, students build, test, and refine tracks as they explore how gravity, momentum, magnetism, and kinetic energy influence each marble's journey.The experience begins with guided builds that teach how the system works. As confidence grows, the challenges become more open-ended, providing only a partial setup and a limited selection of pieces. Students must analyze the design, identify what is missing, and complete the track so the marble reaches its destination.
The included GraviTrax Switch logic game adds another layer of challenge with 30 increasingly difficult puzzles that require careful planning and problem-solving. Clues and solutions are available when needed, though the final challenges are intentionally left for determined builders to solve independently.
As students experiment with height, speed, curves, and specialized elements such as the transfer element and magnetic cannon, they gain a practical understanding of engineering principles while developing persistence, spatial reasoning, and creative problem-solving skills.
Part marble run, part construction set, and part physics laboratory, GraviTrax Academy turns abstract STEM concepts into something students can build, test, and experience firsthand.

So Much Fun

I love how Timberdoodle puts these kinds of kits into their curriculum. It gets my kids working with their hands and using their brain in a different way. This has quickly become a new family favorite and both kids are eager to get to it. This is a great incentive to get the rest of their schoolwork done so they can work on it again. Perfect for any family looking to stretch their kids brain power while having fun!

Lots of pieces!

I wish this were a little more sturdy, but it was fun for the first few uses. I don't know that I would purchase again, though, honestly.

Amazing STEM kit
Brook M.
This has been so much fun for my daughter! She loves building the tracks and watching the marbles go down them. I love that she can create her own tracks as well!
