Hair Coloring Experiment
We test a new brand of red hair coloring (Red Hair Paint) on 6th grade students at Beville Middle School to see how well the coloring “takes” and lasts on different colors of hair. We compare “Red Hair Paint” to a popular brand already being used, L’Oreal. We test both brands of coloring on 40 students (10 blonds, 10 brunettes, 10 with black hair and 10 with red hair)…some with straight hair and some with curls. The students use the coloring for two months, under identical washing and combing conditions and in the same kinds of environments (temperature, humidity, etc). Identify the following:

DEPENDENT VARIABLE
CONSTANTS
