Is this a good way to lose weight?

Lesson idea. A brief explanation of an investigation in to the load carrying capabilities of bridges of varying length and cross sectional area, each built from a piece of A4 paper.

Teaching approach. This activity supports a number of learning types:

  • small group work(ta) - investigation conducted by small groups reporting back to the class.
  • whole class(ta) dialogue(ta) - discussion of each situation open-ended questions(ta) – why did this happen? what do you think causes this movement?
  • peer assessment(ta) – do peers agree?
  • project work – linked in with the rest of the activities in this OER, topic work in design and technology, literacy, numeracy
  • inquiry(ta)-based learning – initial presentation to the class can be framed as a problem for them to solve; co-enquiry – children working collaboratively
  • arguing and reasoning(ta) – persuading each other about their explanations.
  • exploring ideas – developing understanding of key scientific principles.
