T1 W6

FOCUS / ARONGA learning intentions:

• We are FOCUSING on our context of wai safety by explaining the differences between densities in salt water and fresh water and identifying the relationship ( if any) of this with drowning rates.
• We are FOCUSING on our context of wai safety by explaining the process of drowning on the human body and discussing the affects of this.

Kia ora ākonga, this week we will be looking at the densities of ocean/salt water and freshwater and comparing these to see if there is any correlation between this and drowning  rates.

Plan for the week is as follows: 

Tuesday/Wednesday: Temperature, salinity and density experiment 

Thursday/Friday: Lung compliance, parts of a lung, and what happens to this during drowning. 

Success Criteria: 

• • describe how temperature affects water density
  • describe how salinity affects water density
  • offer simple explanations of how climate change may impact the oceans’ chemical and physical properties.
  • Be able to describe the process of drowning on the body
