3Doodler has teamed up with LEGO to create five building Challenges that are all based on teaching science and engineering principles from the Science, Technology, Engineering, and Mathematics curriculum (STEM). Students are prompted to try building a Newton's Cradle, Catapult, Pulley, Rollercoaster, or Trampoline by using LEGO blocks and then a 3Doodler to augment the structure and fill in more flexible parts. Each Challenge comes with a YouTube video, Advanced Challenges and Reference Materials so lessons can be tailored to students of all ages.
