Section 4: The Role of Density in Sinking or Floating: Relational Causality
This section extends the concept of Relational Causality to the phenomenon of sinking and floating. It engages students in RECAST activities to help them restructure their models of sinking and floating from Simple Linear models to Relational Causal models. It encourages students to connect these understandings to a range of real world phenomena.
