#### Transcript of Untitled Prezi

How does the amount of baking powder impact the height and texture of a muffin?
Hypothesis
The more baking powder added, the larger and softer the muffin will become.
Independent Variable
The amount of baking powder added to each muffin
Dependent Variables
The height (cm) of each muffin
Texture of each muffin
Controlled Variables
Amount of other ingredients (eggs, milk, sugar, flour, corn meal, butter) in each muffin
Time in oven (25 mins)
Temperature of oven (425°)
Observation
The more baking powder, the harder and more crumbly the muffins became. The baking powder didn't noticeably affect the height of the muffins but it did impact the width. The more baking powder that was added, the wider the top of the muffins came out.
