Kia Ora,
Aim: To make hokey pokey using sugar, golden syrup and baking soda.
When the sugar and golden syrup combine what the baking soda it froths and makes carbon dioxide gas. This is why the hokey pokey has bubbles.
Materials:
1. 2 Tablespoons Golden Syrup
2. 4 Tablespoons sugar
3. 1 Heaped teaspoon of baking soda
4. Pot
5. Tablespoons and teaspoons
6. Bunsen burner
7. Grease proof paper
Method

2. Bring to the boil and simmer gently for 5 minutes.
3. Add baking soda and stir vigorously
4. Put the hokey pokey on a piece of grease proof paper to cool.
The more the sugar syrup is cooked the browner it becomes. If it is left cooking for to long your hokey pokey becomes burnt.

1. Why do we stir it? We stir it to make sure the sugar and baking soda doesn't get all clumpy.
2. Explain why the hokey pokey rises and has bubbles? It has bubbles because it has carbon dioxide.
