Term 4 Week 5

PLAN & DO / WHAKAMAHI learning intentions:

• We are PLANNING our content of Chemistry through the context of Halloween by applying our understanding of physical changes and performing an experiment to separate these through chromatography and density separation.
• We are PLANNING our content of Chemistry through the context of Halloween by preparing a density separating experiment in the form of a lava lamp to demonstrate how liquids separate according to density differences

Kia Ora ākonga, 

This week we will be looking at how to 'undo physical changes. Two ways of doing this is chromatography and density separation. We will be conducting 2 experiments to undo these physical changes. 

Plan for the week is as follows: 

Tuesday:  What is chromatography / Candy chromatography experiment 

Wednesday:  Density separation / lava lamp experiment 

Thursday:  Graphing skills 

Success Criteria: I can/have...

• Be able to understand and describe what chromatography is 
• How chromatography is used to separate mixtures into their separate compounds 
• What is density separation? How do lava lamps show us physical change separation
