      Test and adapt cam mechanisms

      Lesson details

      Learning outcome

      I can test and adapt mechanisms.

      Key learning points

      1. Testing mechanisms repeatedly ensures the function of the product.
      2. Finishing the automaton figures or models ensures the product looks effective.

      Keywords

      • Effective - works well, performs as expected

      • Function - work in a particular way

      • Aesthetics - visual qualities, how something looks

      • Usable - able to be used

      • Durable - hard-wearing, long-lasting

      Common misconception

      Finished products cannot be changed.

      Adaptations can be made to individual components in a product to improve effectiveness.

      Teacher tip

      Pupils should only make reasonable changes to their automaton products. Products which do not function correctly despite reasonable adaptations could be used as examples for discussion alongside functioning products.
