Question

carmen was learning to bake bread at home. her first few batches of dough did not rise, or expand, as much as they should have. carmens mother noted that the kitchen was cold and suggested that the dough might not be warm enough to rise. carmen decided to test her mothers 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. she left the other three bowls on her desk in her upstairs bedroom, where the temperature was 80°f. after one hour, carmen measured the size of each dough ball. complete the sentence. in this experiment, the temperature where the dough was left to rise was a dependent variable an independent variable

Explanation:

The temperature is manipulated (63°F vs 80°F) to see its effect on dough - rising. It is not affected by other factors in this experiment, making it an independent variable.

Answer:

an independent variable
