Every Who down in Whoville liked Christmas a lot...
Grinch Day engineering challenge: building the grinches sleigh out of two candy canes, wrapping paper, string, and tape. Must be able to hold 5 presents (unifix cubes) while being pulled up a hill! They did a great job working together! Each team designed a sleigh, built it, tested it, and reevaluated their design. They had some very smart ideas!
