Description
Guide children ages 6–12 through a hands-on paper-bridge investigation using paper, blocks, rulers, counters, and recording sheets. Children plan a fair test, measure the bridge span, test how many counters each design supports, and record and compare results using evidence. The guide also explains how to keep tests consistent and change one design feature at a time. Reach for it during a math, science, or engineering activity when children are ready to test, discuss, and improve their designs.
