John watches his grandmother bake bread. He asks his grandmother what makes bread rise. Grandma explains that yeast releases a gas as is feeds on sugar. John wonders if the amount of sugar used in the recipe will affect the size of the bread loaf. He decides to bake a couple of breads using different amount of sugar.

The independent variable is the amount of sugar. The dependent variable is the size of the bread loaf. The two constants are the oven and the temperature that the bread is baked at.
