In a science fair I'm asked to research my topic. What all do I have to put for research? Is she asking for materials and procedure?
I would say that in order for such a question to be effectively answered, referring to your teacher's or instructor's expectations would be of vital importance. This would probably transcend all other insights offered because they are the one who is directly assessing you. I think that selecting a topic area would be one of the most important elements to research. You would be able to gain more out of the research and conduct a more thorough scope of research if you are selecting a topic you like or about which you possess some level of passion. Your research should highlight significant forays into this field from other scientists, as well as what you actually plan to do with the experiment. Designing your experiment would also be an area where you would need to ensure that you detail a lab protocol- a hypothesis that will guide your experimentation, the detailed procedural steps taken, as well as the data and conclusion to your findings.
Your teacher isasking you to do some research for the background of your project; materials and procedures are different sections of a science experiment. For a research section, you have to look up, in reputable, peer-reviewed literature, what is already proven or suspected about your topic. You do not want to re-invent the wheel, to use a cliche. For example, if you are interested in researching what temperatures enable a particular type of plant to grow the best, you would have some research on what is already known about how other plants grow at different temperatures. If nothing has been done on your particular plant, you would hypothesize based on what is known about similar plants. Or you could be seeking to prove or disprove something that is already thought to be true.
