Hello!
One thing you could try is showing that chocolate (or more correctly the fat, cocoa butter) has a number of different crystalline states that have different properties.
In simple terms, when you cool down molten chocolate, it can solidify into different states which have different properties. The rate at which the chocolate is cooled deteremines a lot about the texture, melting point and 'mouth feel'.
So...you could get the children to melt the chocolate (in a cooking room?) and try cooling it at different rates - in a fridge, in a freezer, at room temperature or submerged in warm water bath. They could then taste each chocolate (the best bit!) and compare the texture, taste etc to see which is best.

You could always look at how we taste, by comparing milk chocolate with dark chocolate.

Woiw,

Everone is describing a BTEC topic that we do with year 10! And they say we are not dumbing down!
