Please help me answer the following questions.

1. Give 2 examples of hypotheses that you could test by conducting a controlled experiment.

2. A student hypothesizes that exercise will increase clothespin squeezing rate. What is the dependent variable? What is the independent variable? What other variables should be kept constant?

3. A student hypothesizes that eating pizza will increase test scores? What is the dependent variable? What is the independent variable? What other variables should be kept constant?

~ Thank You For The Help.

Respuesta :

1. I answered that earlier.

2. -Dependent Variable (Variable affected by change): Clothespin squeezing rate

-Independent Variable (What is changed): amount of exercise

-Constant: Type of exercise and Type of clothespins


3. -Dependent Variable (Variabled affected by change): Test Scores

-Independent Variable (What is changed): What they eat (Pizza)

-Constant: Type of pizza and Type of test
