Build a domino run and set off a chain reaction that demonstrates STEM principles including cause and effect, force and motion, and more. This set is ideal for learning in the classroom, at a STEM club, or at home and children will have great fun setting up and setting off their domino runs. The included STEM challenge cards have 8 challenges that start with 2 simple set-ups and become more challenging and complex. The cards also encourage children to create and design their own runs. This 59-piece set includes 45 dominoes, 14 STEM-focused building components, and STEM challenge cards featuring 8 repeatable challenges, and 6 bonus challenges. Pieces are easy to wipe clean after use, and store inside the reusable packaging. Children will have lots of fun setting up, starting and watching their own STEM-filled chain reactions with colourful dominoes in the STEM Explorers™ Domino Action set. As they do the 8 challenges on the included STEM challenge cards and using the 59 included pieces, young scientists will see chain reactions, kinetic forces, and more right in front of them. The included STEM challenge cards have 8 challenges that start with 2 simple set-ups and become more challenging and complex. The cards also encourage children to create and design their own runs. This set is ideal for setting up simple domino runs in the classroom, at a STEM club, or at home and providing children with a fun and immersive STEM learning experience that will encourage their critical thinking, problem-solving and observation skills.
