This gives the following setup for a good scientific question:

“What is the effect of [Experimental factor] on [Scientific factor] in [Organism]?”

For example

Observation: Your mark for the last math test was a 8.8 and your best friend only got a 4.4. You want to know why you had a much better grade than your friend.

Then you remember that your friend forgot to take the math book home the night before the test. And you wonder if the time you study for a test has an effect on the grade you get.

And you wonder if the time you study for a test has an effect on the grade you get.

Scientific question:

What is the effect of the time you study for a test on the grade you will get?

Hypothesis: 

Studying a subject for a longer period of time will result in a higher grade.

Research Question and Hypothesis 

From now on I will not water this plant anymore.

What could be my research question? 

What could be my hypothesis?

- What is the effect of ..A... on ..B... ? 

-  ..A... will ........ (increase, lower, etc.) ....B..... .
