Strategy Sphere

    This technical problem requires teams to design and build two devices that will mechanically propel balls through a circular hoop. The location of the devices will determine the value of the points scored when the ball passes through the hoop. Teams will also create a device to retrieve the balls after they are launched. All aspects of the problem solution will be integrated into a theme about how a change in the Earth's geosphere affects the Earth's atmosphere.
