The Scientific MethodAsk a question
(based on observations)
Form a hypothesisCollect the data (to test the hypothesis)
Analyze the dataDraw conclusions

Asking a research question
Making an observation (information obtained through the use of senses) starts the scientific process with a research question.

Forming a hypothesis
When observations are joined by an inference (drawing logical conclusions based on what you know and what you have learned), then a hypothesis is formed.

Collecting data
We plan an experimental design in order to test the hypothesis. The experiment generates information which we collect.

Analyzing data
Data collected from the experiment has to be analyzed to make sense out of it.

Draw and report conclusions
Finally, the collected and analyzed data shows that either the hypothesis was supported or not.
