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: INDEPENDENT VARIABLE LEVELS OF THE INDEPENDENT VARIABLE

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: INDEPENDENT VARIABLE LEVELS OF THE INDEPENDENT VARIABLE DEPENDENT VARIABLE CONSTANTS CONTROL REPEATED TRIALS EXPERIMENTAL GROUP (what we are testing it on) Does Salt Affect Boiling Point of Water? A student wonders if adding salt to fresh water will change the temperature at which the water boils. In her kitchen, she puts 1L of fresh water into 2 pans (one pan is large, the other is small), then adds 50 grams of salt to the water in the small pan. She places both pans on the stove, uses a thermometer to obtain their starting temperatures and then turns both heating elements to the same high temperature. She continues to monitor the water temperatures in both pans of water until they both boil. Identify the following parts of the experimental design process.
