About:

This printable engineering worksheet helps 3rd graders brainstorm and design bridges by exploring what makes them strong. Students circle ideas about bridge strength (triangles, cables, supports, thick beams), choose a bridge type (truss, beam, arch, suspension, cable-stayed, or cantilever), identify why their design is strong and stable, and draw their bridge with labeled parts. Use during a STEM unit on structures, engineering design projects, or science classwork.
