Transform KS2 children into engineers and bridge builders. This cross-curricular topic pack explores bridge design, structures, and the science of forces through seven hands-on activities — including a spaghetti and marshmallow build challenge and the story of Brunel.
Included Resources +
This pack includes seven activity sheets with accompanying lesson plans transforming KS2 children into engineers and bridge builders through hands-on design, testing, and historical investigation.
• Classifying Bridges — explore beam, arch, suspension, and cable-stayed bridge types and their unique features
• Investigating Local Bridges — fieldwork and observation of bridges in your local area
• Spaghetti and Marshmallow Bridge — engineering design challenge to build and test bridge strength
• Isambard Kingdom Brunel — study of the famous Victorian engineer and his achievements
• Bridge Load Testing — investigate how much weight different bridge designs can support
• Structure Investigation — explore how shapes and materials affect bridge strength and stability
• Design And Build A Bridge — apply learning to create an original bridge design

Curriculum Alignment +
Aligned to the KS2 Design & Technology National Curriculum. Covers structures — designing and making functional structures, investigating and analysing existing bridges, applying understanding of how shapes and materials affect strength and stability, and evaluating and improving designs through iterative testing. Integrates with KS2 History (Isambard Kingdom Brunel — a significant Victorian engineer), Geography (Investigating Local Bridges — human geography and infrastructure), Science (Year 4 — forces and how they affect structures), and Maths (Year 3 — measuring and recording data).
Teaching Tips +
Spaghetti and Marshmallow Bridge is the standout challenge — run it as a timed team competition to build the longest span that can hold the most weight. It never fails to generate excitement and genuine engineering thinking. Bridge Load Testing works brilliantly as a fair test — use identical weights (pennies or cubes) and record results in a table before drawing conclusions about which design is strongest. Isambard Kingdom Brunel pairs naturally with a virtual visit to the Clifton Suspension Bridge or SS Great Britain for real-world context. Investigating Local Bridges is ideal as a homework or family activity — children photograph and sketch bridges near their home and bring findings back to share with the class.
