Question

the passage below describes an experiment. meg was learning to bake bread at home. her first few batches of dough did not rise, or expand, as much as they should have. her mother noted that the kitchen was cold and suggested that the dough might not be warm enough to rise. meg decided to test her mother’s suggestion. she made a large batch of dough and divided it into six equal - sized balls. then she put each ball into a bowl. she left three bowls on the counter in the kitchen, where the temperature was 63°f, and left the other three on the desk in her upstairs bedroom, where the temperature was 80°f. after one hour, meg measured the size of each dough ball. identify the independent variable and dependent variable in this experiment. the size of the dough ball the temperature where the dough was left to rise

Explanation:

• Independent variable: The factor changed by the experimenter (Meg) to observe its effect. Here, she changed the temperature (63°F vs 80°F) where dough was left, so it's "the temperature where the dough was left to rise".
• Dependent variable: The factor measured/observed as a result of the independent variable. Meg measured dough ball size, so it's "the size of the dough ball".

Answer:

Independent variable: the temperature where the dough was left to rise
Dependent variable: the size of the dough ball
