Slide 2

The Scientific Method The scientific method involves a series of steps that the are used to investigate a natural occurrence. The Steps Include Problem/Question Research/Observe Form Hypothesis Experiment Analyze Results Conclusion

Slide 3

Ask a Question or I.D a Problem Example: Energy Drinks and sleep deprivation have a direct correlation with each other

Slide 4

Research/Observe Research/Observe: Research the topic at hand and take notes. Example: We fine that certain energy drinks contain caffeine, vitamins, and stimulants that prevent sleeping hormones in the brain to take effect

Slide 5

Form Hypothesis Hypothesis: A proposed explanation to the question. Example: Students who consume a larger quantity of energy drinks will sleep less during the night.

Slide 6

Experiment Experiment: Develop procedure. Outcome must be MEASURABLE. Example: Divide class in thirds. Have one group receive no drinks, one group receive 2 drinks per day and one group receive 4 drinks per day. Record group average sleep.

Slide 7

Analyze results Go over results of experiment Example: Energy drinks have a direct relationship with hrs slept per night

Slide 8

Conclusion Report on what the experiment told us. Example: Those who receive more energy drink supplements will sleep less per night

Slide 9

Variables All experiments within the scientific method have variables. Independent variable: Manipulated or changed by the experimenter. Ex. Energy drink amount Dependent Variable: The outcome from the experiment that is measured. Ex. Hours of sleep
