Science B37: Testing Bridges


Award-winning video and lesson investigations for young children on the topic of bridges

Product Description

Video and lesson investigations on the topic of bridges. Key concepts include:

  • There is a limit to the load that a bridge can support.
  • Designs that use triangular shapes and arches can make strong bridges.
  • Real bridges cannot be tested to destruction.
  • Making a testing model bridges for strength of design and materials is useful. Structural design and material strength have to be combined to make an efficient bridge.
  • Where the bridge is, and its intended use, affect the design.
  • A bridge designer must consider where the bridge is to be located and its intended use.
  • Construction costs can be an important factor.
  • In addition to load bearing, bridges have to be strong enough to withstand other forces.
  • They must be safe in storms and not be adversely affected by rain, snow, ice and intense heat.
