Steering, propulsion and buoyancy were the topics at-hand during the Marion Natural History Museum’s afterschool group’s latest program, “Submersibles” with engineer Mark Whalen. The students had a chance to conduct a variety of experiments and create their own mini-submersibles to take home. Many thanks go to Mark Whalen, engineer with Sippican/Lockheed Martin for all his hard work pulling this program together for us. Photos courtesy Elizabeth Leidhold
