…Do you have elementary children who need more STEM exploration? Join us 10:0am Wednesdays! I am using the LEGO 9686 Simple and Powered Machines kit to teach the concepts of simple machines by building fishing rods, flywheel cars, sail cars, windmills and more out of LEGO Technic. This is not a robotics class. It does teach the engineering principles for building complex vehicles and attachments. I have taught Physics & Engineering using this kit to multiple groups of K-5 homeschoolers, most recently this last fall, so I am quite familiar with these builds.
