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? ~ you for the .

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

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

good lesson
