Fizz Pop Froth

In science we are learning about change. Change happens when we mix or combine two different reactants (substance) together. When this happens a chemical reactions take place. Today Mr Godin showed us a science experiment. He combined 2 reactants which were baking power and vinegar together, then suddenly bubbles started appearing on the top of the bowl. Then Mr Godin told us to stop taking for a second, and all you could hear was a fizzing noise. It was a bit like the fizzing noise that you hear when you pour a cup of coke
