The first and second grade engineers have been working very hard on their windmills! This challenge has two parts. First, they must design and create efficient blades. The class has determined that efficient blades work quickly and easily. After the blades work efficiently, they are to connect a load, and continue to add weight to see how efficient their blades are. There are several groups that have designed blades that can lift 8 or 9 pennies! Wow!
