Flexi Physics

We were learning about Flexi Physics.
I found it hard to write a few of them.

Fizz,Foam and Froth

We are learning how to make things fizz,foam and froth.
I enjoyed doing the experiment because I love doing them I liked learning how to make things fizz, foam and froth.
I found it challenging to write about it.

Fizz, foam and froth

Have you ever wondered what makes fizz foam and froth? A physical change is when say there is water and you freeze it.I t will turn into ice. But you can change it back to water. A chemical change is irreversible. The first thing you need to do is to label the cups then pour in baking soda then add white vinegar. Leave it there for an hour. Then it should start to fizz foam and froth. It fizzes, foams and froths because of the baking soda and white vinegar. That is a chemical change.
