What do I think is the answer to my question?
Why do I think this? The answer you choose is your hypothesis,You will prove it right or wrong by perfoming an experiment,. If you were to think about the sky question, your hypothesis might be that the color of the sky is related to the position of the sun,
How can I prove my hypothesis?
This is where the experiment comes in．You have to test your hypothesis．If you wanted to find out how light affects plant growth，you could plant seeds in a number of containers．Then you could expose the plants to different amotmts of light and compare the growth rates．
How can I present my results?
You might display your question and hypothesis on poster boards．You might then add pictures and graphs．A great science project also states a conclusion．A conclusion of the plant experiment might be The plants that got the most light grew the fastest．
