I'm a beginer at a science fair i need a backround information but i dont no what to write?

Question

this project is do plants grow better with cola or water i no the answer but why and what should the backround be water? cola? or plants??? please helpppp meeeeee!!!!!!!!!!! and i need proof

Answer 1

I would start with telling what plants need to grow. Than you can go into the contents of cola. You can also state your theory as to what will happen to a plant that gets cola. I would then run my own experiment using two plants; one with water and one with cola. You can keep a log of what each plant does and how it grows. You can state the changes that you see and than the conclusion of the effects of giving your plant only cola. Then I would end by talking about what you think the effects cola has on people's diets.

Answer 2

Mrs. A had a good answer, but I'll expand on that by adding that you want to draw on the scientific method. There's a pretty good tutorial on it here:

In judging your project, they'll want to see that you identified a question and proposed a hypothesis. You've already stated your question (do plants grow better with cola or water?). Make sure that you clearly outline in your background what you hypothesize to be the answer to this question and why. If you adhere to the scientific method by developing a question, hypothesis, experiment, data, and conclusion, it'll be a very strong project. good luck!
