The steps of the scientific method with definitions of each step and an example
Terms in this set (7)
State the Problem: Find out what your problem is.
- Define the problem clearly as possible
Bike making a noise
Front brakes making a loud noise.
Luke's ipod stopped playing music in one earphone.
Gather Information: Gather data about the problem.
- make good observations using the 5 senses:
ex: Touch, Taste, Smell, Sight, Hearing.
He checked all his other songs and found they all did the same thing.
Form a Hypothesis: Form a logical idea of the answer to your problem.
- Hypothesis: A prediction that can be tested.
Luke decided he would try a different set of headphones and see if that helped.
Test The Hypothesis: Use an experiment to test your logical answer to the problem.
- Use controlled conditions to test your hypothesis
A. Controlled experiment: Everything in an experiment that is the same except for the variable.
~ Variable: Something in an experiment that you change, only one per experiment.
~ Constant: Factors in an experiment that stay the same.
Luke asked his friends Calum, Michael, And Ashton to borrow their headphones. All of the other boys had the same brand of headphones ( Beats) and the same iPod ( gen.5) Except he switched ears. He found all the other headphones worked. Luke tried the headphones in Calum's ipod, and found they didn't work either.
Analyze Data: Go over all the data you have/ go over conclusions.
- Keep a journal of your records.
Luke wrote down his findings and read over all his notes.
Draw a Conclusion: Based on data and observations, conclude the answer to your hypothesis.
- should be logical answers to the question based on data and observations.
- if needed, retest this theory ( possibly with a new hypothesis)
Luke concluded with his data and and observations that his headphones were broken and he needed a new pair.
Share results: report journal to classmates, or publish a journal of findings.
Luke shared his findings with his mom and friends, and his mom bought him another pair for his birthday.
