I need to know at least 5 control variables for the following questions.

1.Which tennis shoe, Nike or New Balance, will help me improve the time it takes me to run the 100-meter dash?

2. Does Bazooka or Double Bubble gum blow a bigger bubble?

Here is a discussion of dependent and independent variables. Read this, then make your list following the rules.

what? im sorry but what am i suppossed to be reading?

This site should help you.

To identify control variables for the given questions, we need to understand the purpose of control variables. Control variables are factors that are kept constant or consistent throughout an experiment to ensure that any observed effects are due to the independent variable(s) being tested. In other words, control variables help eliminate potential confounding factors that could affect the results.

Let's consider each question and identify at least 5 control variables for each:

1. Which tennis shoe, Nike or New Balance, will help me improve the time it takes me to run the 100-meter dash?

Possible control variables:
a) Surface: Use the same type of running surface for both shoes to ensure consistent conditions.
b) Runner: Keep the same person (with the same athletic ability) wearing both shoe brands to eliminate individual differences.
c) Distance: Use the same 100-meter distance for all trials.
d) Warm-up: Ensure the runner warms up equally before each trial to eliminate the influence of differing levels of preparedness.
e) Conditions: Run the trials under similar weather conditions (temperature, humidity, wind, etc.) to minimize their impact.

2. Does Bazooka or Double Bubble gum blow a bigger bubble?

Possible control variables:
a) Amount of gum: Use the same amount of gum from each brand for fairness.
b) Chew time: Have the participants chew both brands for the same duration to ensure consistent conditions.
c) Chewing technique: Instruct participants to use similar chewing techniques for both brands to eliminate variations in bubble-blowing.
d) Bubble-blowing method: Standardize the method of blowing bubbles across both brands (e.g., participants must blow one large bubble without combining multiple bubbles).
e) Measurement technique: Use a consistent measurement method to determine the size of the bubbles, such as a ruler or measuring tape, to ensure accuracy.

Remember that control variables may vary depending on the specific experiment or study design. These examples should help you understand the concept and provide a good starting point.
