Some materials that can help you prepare for your test on Scientific Method
Steps of the Scientific MethodDetailed Help for Each Step
Ask a Question: The scientific method starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where?
And, in order for the scientific method to answer the question it must be about something that you can measure, preferably with a number.
Do Background Research: Rather than starting from scratch in putting together a plan for answering your question, you want to be a savvy scientist using library and Internet research to help you find the best way to do things and insure that you don't repeat mistakes from the past.Background Research Plan
Construct a Hypothesis: A hypothesis is an educated guess about how things work:
"If _____[I do this] _____, then _____[this]_____ will happen."You must state your hypothesis in a way that you can easily measure, and of course, your hypothesis should be constructed in a way to help you answer your original question.
Variables for Beginners
Test Your Hypothesis by Doing an Experiment: Your experiment tests whether your hypothesis is true or false. It is important for your experiment to be a fair test. You conduct a fair test by making sure that you change only one factor at a time while keeping all other conditions the same.You should also repeat your experiments several times to make sure that the first results weren't just an accident.
Conducting an Experiment
Analyze Your Data and Draw a Conclusion: Once your experiment is complete, you collect your measurements and analyze them to see if your hypothesis is true or false.Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again in a new way.
Data Analysis & Graphs
Communicate Your Results: To complete your science fair project you will communicate your results to others in a final report and/or a display board. Professional scientists do almost exactly the same thing by publishing their final report in a scientific journal or by presenting their results on a poster at a scientific meeting.Final Report

What is Scientific theory?
In science, an idea starts out as a hypothesis, or an educated guess as to why or how something is happening. Those hypotheses undergo a lot of experimental trials in various ways and data is collected. Over time, as more and more data is collected, a hypothesis can become a scientific theory. The more a hypothesis is supported by many different experiments and many different experimenters, the stronger the scientific theory. However, scientific theories can change as more data is collected.
Overview of the Scientific Method
The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way.
Just as it does for a professional scientist, the scientific method will help you to focus your science fair project question, construct a hypothesis, design, execute, and evaluate your experiment.
Research Question: The research question is the single most important part of the scientific method. Every part of your project is done to answer this question. The research question is sometimes formed as a statement and is called the "Problem" or "Problem Statement."
Hypothesis: The hypothesis is an "educated guess," formed as a statement, that you propose to be the answer to the research question. An educated guess is based on some prior knowledge.
Experimental Design: Plan an experiment in which you can test your hypothesis.
2 kinds of data/observation:
Qualitative - tells the quality like color, odor, taste
Quantitative - using measuring devices like ruler, thermometer etc.
Materials: List all supplies and equipment.
250 ml. glass beaker
150 ml. Lime Water
10 g. Baking Soda
Procedure: The procedure is a somewhat detailed, step - by - step description of how you conducted your experiment. Example: "After 1 minute, I stirred in the baking soda and timed the reaction to be 45 seconds."
Results: The results is usually in the form of a statement that explains or interprets the data. You do not go into any detail or explanations here. You simply say in words what your data is telling you. Example: "Test Plant 3 showed little difference in growth rate as compared to the Control Plant."
Conclusion: The conclusion is a summary of the research and the results of the experiment. This is where you answer your research question. You make a statement of whether your data supported your hypothesis or not. You may have data that supported part of your hypothesis and not another part. You may also have data that did not support your hypothesis at all. In this case, you may explain why the results were different.
Application: The application is how the information or knowledge gained in the experiment can be used. It is not often included in science fair projects.
Resources: One of the most important things for a student to do is recognize the people and resources used in developing and conducting the project. Name the people who offered knowledge or helped, and list the web sites, retail stores, magazines, books, computer programs, etc. that were used as sources of information or supplies.
