Young engineers come together in the classroom to design, build and test bridges based on real world engineering principles with the STEM Explorers Bridge Builders Classroom Set. There are enough supplies in this set for 5 children to collaborate on projects just like real engineers and construction crews do! As they work together to build a suspension bridge, air bridge and more, theyll also be building transferable skills including critical thinking, problem-solving, communication, collaboration and more. After the learning fun is over, everything stores neatly inside the reusable storage tote.
