Competition

• Regional Challenge Type 1
• State Challenge Type 2
• National Challenge Type 1 or Type 2
• As chosen by Event Supervisor
• Type 1 a load bearing structure that must be a
  tower, a bridge, or a cantilever.
• Type 2 a device that must transport one or more
  balls from start to an end location
• Must be a ramp, a catapult, or a bouncer device

11
Competition

• Unless otherwise stated in the instructions, the
  devices must be freestanding and must not be
  attached to a tabletop, floor, ceiling, or any
  other support.
• Teams will be given specific challenge
  instructions just prior to their competition

Examples

• The following pictures give an idea of the
  structures involved. They may contain items
  which are not legal but were used to teach
