Structures & Mechanisms – Stronger Designs
Explore how shapes and joins make structures stronger; simple levers/wheels.
Curriculum map: Science and Technology AoLE · PS3
Engineers test ideas – triangles, wide bases and good joins matter.
Strong shapes
Triangles in bridges/towers; wide base for stability.
Mechanisms
Levers, wheels and axles – change movement or make work easier.
Why test a model before the final version?
Find weak points and improve the design.
Practice
1. Which shape is often used for strength in bridges?
2. What does a lever help you do?
