The little red hen

  What do you think it was that helped turn all the ingredients into bread?

"A hot oven", said Dev.

"Flour", said Bailey and Taleen.

"Water", said Bryson.

"Eggs", said Yamato.  

We investigated 'yeast' which is one of the ingredients used to make bread.

What will happen when we add yeast with warm water and sugar?

 We dissolved some sugar into warm water and then added the yeast. We put a balloon on the top to see if it would fizz like the baking soda and vinegar did.

 We left the bottle in the sun for 40 minutes and came back to observe any changes. 

"The balloon has air in it!"

"The water has gone lumpy like vomit".

"The water looks all dirty".  

Our conclusion is that yeast changes the ingredients and makes them a little bit thicker.
