Floating and sinking

Is getting in the bath a way to lose weight?

Lesson idea. This activity is based on materials that float and sink; also mass in air and mass when there is an up-thrust.

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 of their explanations.
  • exploring ideas – developing understanding of key scientific principles.
