How can you create a great science fair project？．You can start by asking yourself some questions． What is interesting to me? You can connect ainroot any topic to science, Your topic could be plants, worms,dogs，the sky or something else．If you can not think of a topic，search books or the Internet for ideas .Seek help from your teacher or a librarian．Your parents may have some good thoughts too． What question do I have about this topic? A great science project always includes an experiment．Make sure that your question can be answered through an experiment．Here are some examples of questions：Does the amount of light have an effect on how fast plants grow？How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day? How much time do I have before the scienc fair? A great science project always includes an experiment. Make sure that your question can be answered throuth an experiment, Here some examples of questions,Does the amount of light have an effect on how fast plants grow? How much salt is in different kinds of cookies sold at the store? Why does the sky change color at different times of the day? How much time do I have before the science fair? A science fair to be held in two weeks will not give you time for some experiments ,such as growing plants, carefully plan your project so that you allow enough time to perform your experiment accrately. 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 ． When you have finished your project，you may have more questions．A great science project makes you want to learn even more． 64．A great science project always includes ． A．plants in pots                B．results C．an experiment               D．poster boards 65．A hypothesis is a(n) ． A．question           B．idea          C．performance         D．proof 66．We can learn from the passage that ． A．all science projects take about the same amount of time B．a science project involves several steps C．a science project should start with a conclusion D．a science project raises many questions 67．To find out whether cold water freezes faster than hot water,you would first ． A．make a chart to explain your steps B．state your conclusion to convince other people   ， C．think of an experiment to give an answer D．display your hypothesis to prove
