Question

the passage below describes an experiment. while at a cookout, bill noticed that his friend ellie kept her soda in the shade. when bill asked why, ellie explained that she was trying to keep the soda from going flat. knowing that direct sunlight makes objects warmer, bill reasoned that warm soft drinks must go flat faster than cold ones. when bill got home, he decided to test this idea using 12 cans of soda. after opening all 12 cans, he left 4 in the refrigerator, 4 on the kitchen counter, and 4 outside in the hot sun. five hours later, he took a sip from each can to determine how fizzy the soda was. identify the independent and dependent variable in this experiment. the temperature of the soda the fizziness of the soda

Explanation:

In an experiment, the independent variable is what the experimenter changes or manipulates, and the dependent variable is what is being measured or observed. Here, Bill changes the temperature of the soda (refrigerator - cold, counter - room - temperature, outside in sun - hot) to see how it affects the fizziness of the soda. So, the temperature is the independent variable and the fizziness is the dependent variable.

Answer:

Independent variable: the temperature of the soda
Dependent variable: the fizziness of the soda
