THE SCIENTIFIC METHOD Problem =

observation, question, or problemObservation:

Running shoes degrade when exposed to weather

Question: Do mouthguards hinder athletic performance?

THE SCIENTIFIC METHOD Hypothesis =

testable statement describing what YOU think will happenAddition of PIB will

improve the durability of an athletic shoe

Mouthguards will not hinder athletic performance

PIB = PolyisobutylenePIB Uses:-Chewing gum-Medical adhesives-Fuel additives

THE SCIENTIFIC METHOD Experiment =

Ways to test the hypothesisMake PIB-based

material and test the properties

Study to test athletic ability when using and not using a mouthguard

EXPERIMENT Control group?

Experimental group?

Independent variable?

Dependent variable?

Wearing or not wearing the mouthguard

Vertical jump performance

Group not wearing the mouthguard

Group wearing the mouthguard

THE SCIENTIFIC METHOD Conclusion = Statement discussing if

hypothesis is correct or notDetermined that vertical jump was similar

for both control and experimental groupResults lead to the hypothesis being

correct!
