Question

1. how does the temperature of the grill affect the time needed to cook something?(dv) (iv)12. how does the amount of sugar in the mix affect the sweetness of baked cookies?(dv) (iv)13. how does the thickness of rope affect the amount of force required to break the rope?(dv) (iv)

Explanation:

IV stands for Independent Variable (the variable being changed/tested), and DV stands for Dependent Variable (the variable being measured that depends on the IV).

1. For question 11: The grill temperature is the variable being adjusted, so it is the IV. The cooking time depends on the temperature, so it is the DV.
2. For question 12: The amount of sugar is the variable being altered, so it is the IV. The sweetness of the cookies depends on the sugar amount, so it is the DV.
3. For question 13: The rope thickness is the variable being changed, so it is the IV. The force needed to break the rope depends on the thickness, so it is the DV.

Answer:

1. (DV) Time needed to cook something

(IV) Temperature of the grill

1. (DV) Sweetness of baked cookies

(IV) Amount of sugar in the mix

1. (DV) Amount of force required to break the rope

(IV) Thickness of rope
