It was great fun, especially the anticipation of how it would turn out. We discussed the science between the chemical reaction and also used this as a motivation activity for our procedural writing. I think it worked! I have never seen written work happen so quickly and with such focus!
Here is the recipe we used:
HOKEY-POKEY:
Ingredients:
2 tablespoons golden syrup
4 tablespoons sugar
1 teaspoon baking soda
Method:
1. Grease a tray with butter.
2. Put the golden syrup and sugar into a saucepan together and stir over a low heat until the sugar has dissolved.
3. Once the mixture is bubbling, let it bubble away for 7 minutes (important,or it won't set nice and crunchy - gooey hokey-pokey isn't easy to eat.)
4. Take it off the heat, stir in the baking soda, and then (very speedily) spread it onto the greased tray.
5. Let it set - it should start to set immediately.
