#1. SCIENTIFIC QUESTION A testable, scientific question based on observations. How long does Old Spice Odor Blocker body wash eliminate odors? SCIENTIFIC QUESTION
A prediction that describes the relationship between the variables. #2. HYPOTHESIS prediction variables
WHICH HYPOTHESIS IS BEST? 1.Old Spice Odor Blocker Body Wash will eliminate odors for 16 hours. 2.Old Spice Odor Blocker Body Wash will eliminate odors. 3.Old Spice Odor Blocker Body Wash will work best.
#3. EXPERIMENTAL DESIGN
INDEPENDENT VARIABLE What is being tested or compared in an experiment. The cause. The before. YOU Control it! INDEPENDENT cause.
OLD SPICE ODOR BLOCKER What is the Independent Variable? 1.Type of body wash 2.Odor 3.Showers
DEPENDENT VARIABLE The outcome of the experiment – what is being measured. The effect. The after. YOU Measure it outcome measured. after.
OLD SPICE ODOR BLOCKER Dependent Variable: Body odor (time to smell!!)
CONSTANT VARIABLES Things that stay the same throughout the experiment. VARIABLES same
OLD SPICE ODOR BLOCKER What might we keep the same?
CONTROL GROUP The baseline group. Does NOT have the experimental treatment. CONTROL baseline
OLD SPICE BODY BLOCKER This group would have NO body wash. Instead, they would just wash with water. Yum NO body wash
EXPERIMENTAL GROUP The group or condition being tested.condition
OLD SPICE BODY BLOCKER This group would use the Old Spice body wash.
#3. EXPERIMENTAL DESIGN CONTINUED List of materials required Numbered, step-by-step directions/procedures materials procedures
#4. RESULTS Organize collected data in a properly labeled data table. Choose an appropriate graph for collected data. Create the graph. Properly label the graph. Analyze the data – identify trends/correlation (positive, negative, or no relationship) from data obtained in the experiment. RESULTS properly graph label Analyze no
#5. CONCLUSION 5 sentences: - This experiment investigated … - The hypothesis stated … - According to the data the hypothesis was … (supported or not supported) - I know this because … - This is important because …
