When Writing A Research Paper
What you must remember is that somebody might want to test your results so you must make sure that they are able to perform exactly the same experiment with exactly the same equipment.
Here you must describe exactly the equipment and methods you used.
For example, "Mold Growth" tells us nothing whereas "The Effect Of Temperature On Mold Growth" lets everybody know what the experiment is about.
In this section it is important to give the reasons why you picked this experiment and show the background research you did for it.
For a website you should put the exact website address and the date you looked at it.
Not every science report or article insists that you have a bibliography but if you want to follow a career as a scientist it is a good idea to get used to it now.
