Watching your mother bake bread, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wonder whether the amount of sugar used will affect the size of the bread. That is, if you add more sugar, the size of the bread will be larger. Your mother’s recipe calls for 60 grams of sugar to produce a loaf of bread about 1260 cm3 what is the problem

Watching your mother bake bread, you learned that the dough of the bread rises because yeast acts on the sugar and releases gas. You wonder whether the amount of sugar used will affect the size of the bread. That is, if you add more sugar, the size of the bread will be larger. Your mother’s recipe calls for 60 grams of sugar to produce a loaf of bread about 1260 cm3. What is the independent and dependent variables?

independent variable: amount of sugar used

Dependent vairable: size of bread

Explanation:

In a scientific experiment, there are two main types of variables; independent and dependent variable:

Independent variable: This is the variable that is completely under the control and manipulation of the experimenter. The values of this variable can be varied at will, and the effect of the variation affects the dependent variable. In this example, the independent variable is the amount of sugar used, because the amount of sugar used is determined by the baker.

Dependent variable: The dependent variable is the variable that changes as a result of the manipulation of the independent variable. It is not directly under the manipulation of the experimenter, and it is the variable that the experiment seeks to study. In this example, the size of the bread is the dependent variable because it depends on the amount of sugar used.
