Stages of the scientific method

Show how you use the scientific method in everyday problem solving.
Come up with one original personal example of how you use the scientific method.
Take a look at this example of what I'm looking for. Please note that as I formulated my hypothesis I stated three possibilities as to why the car was not starting, as part of my experiment I have to proof which one is the valid one)

Event Method Step

Car will not start Observation

Dead battery? Hypothesis 1

Ignition problem? Hypothesis 2

Out of Gas? Hypothesis 3

Turn on headlights Experiment 1

Check spark at plug Experiment 2

Check gas gauge Experiment 3

Headlights burn brightly (Battery OK) Analyze results 1

Strong ignition spark (Ignition OK) Analyze results 2

Gauge says empty tank (No gas) Analyze results 3

Car needs gas to run Generalize form principle
