Last Thursday students rotated through a series of stations to explore friction, buoyancy, magnetism, torsion, and shear. They also investigated the Tacoma bridge collapse by viewing a film clip on YouTube and answered a series of questions. I am including the clip on this post for those who wish to view it again or show it to friends and family. Please also view the YouTube clip on the post below explaining Archimedes' Principle. It's wonderful.
