What to do?
Lego Design Challenge – Make a Wind Powered Car.
Lego Wheels Kit, Tape, Pipe Cleaners, Ice Block Sticks, Paper and a Hair Dryer for the Wind. The variety of designs were amazing and there was whole lot of trial & error and design thinking happening. Sail designs were modified to be curved and more rigid and a natural progression was to add outrigger like wheels to stabilize the vehicle.
It would be great as a design technology component of an renewable resources / environmental inquiry and I would include more research/investigations into sail design and different types of sail boats.
