Chemistry

What I learnt

- Yeast is alive

- Chemicals are everywhere

-If you add different chemicals to different liquids they change in colour and acid levels/ antacid levels and can become neutral

- You can blow up a balloon using only yeast,sugar, water and a jar (ballon).

- (As seen in the movies) When you add different liquids to other liquids they change colour and then change back, depending on the liquids you add.
