Senior Engineering

Onsite Competition Only

The Engineering competition demonstrates creative ability, collaboration and attention to detail to construct an invention in the spirit of Rube Goldberg. Teams use items from a specified list and will be given an invention prompt at the beginning of the competition. The invention must have at least five steps. A step is defined as a power - whatever force causes the next reaction to take place. Teams will write an explanation to communicate the elements of the invention and creative concepts. Teams will be required to interact with judges.

Time Limit: 2 Hours

Competition Guidelines

  • Each club may enter one team of three to five students.
  • Teams will be given two hours to construct the invention.
  • The invention must be constructed on a piece of plywood 24 inches by 48 inches. This piece of plywood will be separate from the materials container.
  • The invention may have parts that suspend beyond the board, but cannot be braced/tethered/supported by anything (i.e. wall or floor) other than the board.
  • The team must use ONLY the items from the specified list and materials must fit into a closed 18 gallon plastic storage container with a lid.
  • Power tools do not have to be placed in the container. Tools must be battery operated.
  • All construction must be done on-site. No steps can be preassembled, construction pieces must be separate and the board must be free of any writing or marks.
  • Electricity will not be available.
  • During the competition, objects may be attached to the board and/or to each other using adhesives (including battery operated glue guns), thumb tacks, nails, screws, wire, or string.
  • The team gets one free touch to activate the invention.
  • SAFETY - Protective eyewear is required for each team member. Teams will not be allowed to participate without protective eyewear.
  • SAFETY - Tools cannot have a knife, box cutter, or any type of blade.
