Students filled the halls of Macatawa Bay School Saturday looking for their way to Mars. Their vehicle for the trip to the Red Planet? A Lego robot. Thirty-six teams of fourth- through eighth-graders strained their brains for West Michigan Lego Mania. The students mission was to create a device to be used on Mars. They were judged for clearing dust from a solar panel and freeing a Mars Rover from a sand dune. Mock Mars settings were set up where the students practiced and were judged.
