Yeast bubbles

In my class we have been learning what makes yeast bubbles

here's what I've done.

Yeast bubbles

Have you ever wondered what activates yeast? First you get some yeast, sugar, and some warm water. Get a cup and put your warm water in the cup and add one and a half teaspoons of yeast and some sugar. Wait 10 minutes. You will have a big yeast bubble in your cup. But if you get another cup and get one and a half teaspoon of yeast and warm water and wait another 10 minutes it will not be as big because the sugar helps the yeast grow. Yeast bubbles are formed by the sugar and warm water making carbon dioxide and the carbon dioxide creates the yeast bubbles.
