Assess educators' ability to design and score a short evaluation for Pre-K–Grade 2 learners that compares simple construction materials (e.g., paper, cardboard, craft sticks, tape, plastic) for building a toy-car bridge by judging strength (weight-bearing, resistance to bending), stability (balance, support across a span), and safety (small parts, sharp edges, secure connections). Scope includes creating age-appropriate prediction and test tasks, observation or recording methods (drawings/photos), and rubrics that require children to choose a winning material and justify their choice with simple evidence while accounting for safety considerations.
