To end our topic of CHANGE we had a master chef cook-off. Each class made something.
Room 7 made hokey pokey to show that..... the baking soda releases all of its gas (CO2) and makes a chemical reaction with the sugar and golden syrup. That makes it bubbly and frothy.
Here is the recipe:
Put 5 tablespoons of sugar into a pot.
Put 2 tablespoons of golden syrup into the pot.
Out the pot on a low heat to dissolve the sugar.
Boil on a low heat for 4 minutes.
Put one teaspoon of baking soda into the pot.
Stir quickly and spoon out onto a greased tray.
