Design and build a sleigh using a WeDo kit, K’nex or similar, that will pull a specific measured weight.

During this unit, students will learn about the Great Pacific Garbage Patch. They will read about the GPGP and then prepare a presentation with their findings and solutions.  Lastly, they will create a prototype to help with the ocean cleanup and use Spheros to maneuver the prototype to pick up trash in water.
