In Room 10 we decided to carry out an experiment.
We did what good scientists do by recoding our predictions before carrying out the experiment and then made observations during the process.
Here we are...
We measured our ingredients to ensure our experiment had the best chance of success.
We observed the changes we saw taking place before our eyes. The ingredients melted and bubbles were forming, once we added the baking soda we were surprised to see how much the mixture was expanding!
The Science: The bicarbonate of soda breaks down with heat to release carbon dioxide gas. The gas causes the sugar and syrup mixture froth and bubble. The bubbles become trapped in the mixture and set there.
We also noticed a change once the hokey pokey had cooled. It changed into a hard and crunchy substance.
I wonder what new ideas we will explore during next week's rotation!
