My science inquiry
For the last two weeks we have been learning about chemical reactions and the periodic table
The main molecule for hokey pokey is baking soda
The science behind hokey pokey is when the backing soda is put in with the golden syrup it heats up and releases carbon dioxide. The carbon dioxide gas makes small bubbles in the sugar and it foams up.
