10Science7 26 Haratua 2014What we will do What we will learnPreliminaries and roll, including notices The importance of starting wellRevisit how Mother Nature balances out the charge on ions
That “free” charges are “snapped up” and how this happens
• Continue “making” ionic compounds
• Use the “bricks” to help us get there.
• Use extra care with complex ions
How to make good use of time while working towards a good score in the End Of Topic Test
Change the due date from “Zenday” How to influence our workstreamNote down some of the main ions used in industry
How people use ions to make money and solve problems.
Revisit the objectives of the unit Have we done what we said we would do?
See how to tackle an excellence question.
