Challenge Objectives

  • Youth learn how to work under pressure.

  • Youth will put their engineering skills to the test.

  • Youth communicate effectively and contribute to the group effort.

  • Youth demonstrate their STEM knowledge.

Challenge Rules

Teams of 2-4 youth

Each team participating must have a minimum of two and a maximum of four youth to be eligible to compete.

Age Divisions | Junior (9-13 years) | Senior (14-18 years) 

Age is calculated as of January 1, 2025. In teams with youth of multiple age divisions, the age of the oldest youth on that team will determine the age division in which the team will compete.

Materials | Specifications | Time

Youth will be provided materials for a timed challenge that will be revealed on the day of the competition. The youth will only need to bring their knowledge of STEM, the Engineering Design Process, and teamwork skills. They will have a set amount of time to design, implement, and test their design prior to the judged event.

Judging

Metric | Placing | Tie Breaker

Youth will be judged on their ability to solve the problem presented to them (criteria based on outcome metric related to the specific challenge), use of the engineering design process, sportsmanship, and leadership & teamwork.
