Question

1. how does the size of a bicycle tire affect the distance it will travel when it is pedaled in a given number of times? constant/control variables: __________ hypothesis/prediction: ________ hypothesis worksheet write a hypothesis for each of the following research problems. identify the dependent and independent variable for each. 1. what effect does high temperature have on the growth of apples? hypothesis: ________ independent variable: ________ dependent variable: __________

Explanation:

1. For the apple - growth problem: The hypothesis could be based on the general understanding that temperature affects plant growth. The independent variable is what is being changed (temperature), and the dependent variable is what is being measured (apple growth).

• Hypothesis: High temperature will inhibit the growth of apples.
• Independent variable: Temperature.
• Dependent variable: Growth of apples.

1. For the bicycle - tire problem: The distance a bicycle travels when pedaled a certain number of times depends on the circumference of the tire (related to its size).

• Constant/Control Variables: The number of times the bicycle is pedaled, the surface on which the bicycle is ridden, the type of bicycle (except for tire size).
• Hypothesis/Prediction: Larger - sized bicycle tires will travel a greater distance when pedaled the same number of times because they have a larger circumference.

Answer:

1. Hypothesis: High temperature will inhibit the growth of apples.

Independent variable: Temperature.
Dependent variable: Growth of apples.

1. Constant/Control Variables: The number of times the bicycle is pedaled, the surface on which the bicycle is ridden, the type of bicycle (except for tire size).

Hypothesis/Prediction: Larger - sized bicycle tires will travel a greater distance when pedaled the same number of times because they have a larger circumference.
