Question

Shawn is planning a scientific experiment. He wants to learn whether time of day has an effect on how far the roses in his mother's garden are open. He plans to measure the diameter of each flower on three rosebushes every hour during a week in the spring.

What is the independent variable in Shawn's experiment?

Answer 1

The independent variable in his experiment would be the length of time, he is waiting or recording to then measure whether or not the flowers will open and the extent that they will open.

Answer 2

Answer: Time of day- Independent variable

Step-by-step explanation:

Independent variable can be defined as the factors which the experimenter can control and the the dependent variable depends on the independent variable.

here, the experiment is based on time of day and how far the roses open. Here, the independent variable is time of the day and the different in the diameter will show whether the time of day has some effect on flower's diameter or not.

Hence, the correct answer is time of the day.
