Question

1. problem: what brand of chapstick will keep my lips feeling the best? experiment: each day test a different brand of chapstick (including one day with no chapstick) to see which day my lips feel best. part of experiment answer independent variable dependent variable constants experimental groups control group

Explanation:

Step1: Identify independent variable

The brand of chapstick (including no - chapstick) is what is being changed, so it is the independent variable.

Step2: Identify dependent variable

How the lips feel is what is being measured and depends on the chapstick brand, so it is the dependent variable.

Step3: Identify constants

Factors like the person's diet, overall health, environmental conditions (temperature, humidity etc.) during each test day that could affect lip - feeling but are kept the same should be considered constants.

Step4: Identify experimental groups

The groups using different brands of chapstick are the experimental groups.

Step5: Identify control group

The day with no chapstick is the control group as it provides a baseline for comparison.

Answer:

Independent Variable: Brand of chapstick (including no chapstick)
Dependent Variable: How the lips feel
Constants: Diet, overall health, environmental conditions during each test day
Experimental Groups: Groups using different brands of chapstick
Control Group: Day with no chapstick
