Watch this video where youth must balance criteria and constraints as they design enrichment toys for animals that are engaging and safe.
Criteria and constraints are often in tension with each other, and youth may need to consider trade-offs in order to optimize their solution.
As youth use this engineering practice, they will come to understand that any solution cannot optimize all of the criteria and constraints, and that their role as an engineer is to find the best solution possible within the full context of the problem.
