Problem/Question
John watches his grandmother bake bread. He ask his grandmother what
makes the bread rise.
She explains that yeast releases a gas as it
feeds on sugar.

Problem/Question
John wonders if the amount of sugar used in the recipe will affect the size of the bread
loaf?
![Page 7: The _____________ involves a series of steps that are used to investigate a natural occurrence. 1. Scientific Method.](https://reader036.fdocuments.in/reader036/viewer/2022070414/5697c01d1a28abf838cd0932/html5/thumbnails/7.jpg)
Caution!
Be careful how you use effect and affect.
Effect is usually a noun and affect, a verb.
“ The effect of sugar amounts on the rising of bread.”
“How does sugar affect the rising of bread?”
