    What about some simple 2 piece jigsaws with the protein/carb on one piece and the enzyme on the other? You could make them yourself out of thin card!

    Or better yet get them to make them. Print off the names/diagrams of the food and the same with the enzyme. They can stick them onto a pice of card then cut ehm in half.

    gGet this on your interactive board

    blow it up so they cant see the writing, use 'control' key and your 'mouse scrolling thing' (not really a key is it)

    Ask them to suggest/write down what the different colours could be then what's happening, perhaps follow it uo with a quick demo of yeat catalses and peroxide, show them the equation,
    and relight a glowing splint a few times to make it more exciting, and prove O2 is produced

    Something I was shown when I first started teaching was to teach it using sponges.
    Get a load of cheap bath sponges and cut different shapes into different sponges. Then put them back together - only every really donw it with lower ability as I have never had a higher ability group that didn't understand the concept, but it did work really well.
  5. Thanks for all the suggestions people - most helpful x x
