Build your own space rover, crane and more using twisting turning gears and then test your machines!
 
There are 9 STEM challenges to complete, or children can use this set for open-ended construction play.
As children build, test and tweak their designs, they also build essential critical thinking and problem solving skills.
This 60-piece STEM building toy includes all of the gears, pulleys, belt drives, and connectors needed to build simple machines, as well as 10 activity cards packed with challenges.
Better yet, the STEM Explorers Machine Makers set also works with all Gears! Gears! Gears® sets (each sold separately) for even more building fun.
Pieces are easy to wipe clean after use, and store inside the reusable packaging.
