Why give Chemistry a context like that? The purpose should be to give students a grounding in the scientific method and sufficient knowledge of chemistry to move on to higher levels.
Because 90% of the kids will have switched off if taught science theory first. I'll repeat - this is level 1 NCEA.
Context is everything - anyway much/most scientific discovery comes from curiosity after observation of some dynamic system. Most 14 year olds probably quite oblivious to interesting things they're seeing, until (hopefully) it's drawn to their attention.
