Answer:
correct sequence:
make an observation
ask questions
construct a hypothesis
test the hypothesis
analyze the results and make conclusions
communicate the results
Explanation:
Scientific method is a set of steps made in order to perform a proper and valid scientific investigation.
Everything starts with an observation, finding something unusual or interesting that we want to test. After choosing our field of interest, we continue to ask a question; why is something the way it is and what is the reason for that?
Every question needs an answer so we propose a possible answer or a hypothesis. Of course, this doesn't have to be correct or final explanation, but it will be the answer which will we put to the test.
After constructing a hypothesis, we need to test it through researching or experimenting in which we will obtain some date.
Results of our experiment in the form of data must be analyzed and used to confirm or denied.
These results, whatever they may be, will help us to make a conclusion which we'll finally communicate, showing it to the other researchers.
