2 The Scientific MethodResearch Question: The research question is the single most important part of the scientificmethod. Every part of your project is done to answer this question. The research question issometimes 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 tobe 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.•Variables: The experiment will contain an element or elements that do not change (calledcontrolled variables or dependent variables) and elements that will change (called manipulatedvariables or independent variables).•Control: The control is a particular sample that is treated the same as all the rest of the samplesexcept that it is not exposed to manipulated variables.•Observation: When you interact with your experiment, you are using your senses to observe.Does it have a smell, make a noise have color, etc.?•Collect Data: As you observe your experiment, you will need to record the progress of yourexperiment. Data can be whatever you observe about your experiment that may or may notchange during the time of the experimentation. Examples of data are values in pH, temperature, ameasurement of growth, color, distance, etc.
3•Journal: All scientists keep a record of their observations in some form of a journal. The journalwill begin with the date and time the experimentor collects the data. Sometimes data will includeenvironmental values such as humidity, temperature, etc. Entries must be written clearly and withdetail of description so that another scientist can read the journal, simulate the conditions of theexperiment, and repeat the experiment exactly.•Data: The data are the values written down as the experiment progresses. Examples of dataentry on measuring plant growth:11/15/04 Control Plant 7.4 mm Test Plant 16.2 mm Test Plant 24.9 mm Test Plant 37.2 mm11/22/04 Control Plant 7.8 mm Test Plant 15.9 mm Test Plant 23.2 mm Test Plant 37.2 mm•Charts & Graphs: When at all possible, illustrations of data are advisable. They create aprofessional appearance and convey a great deal of information. Examples include: Bar Graph, PieChart, X & Y axis Graph, Histogram, etc.
4Materials: List all supplies and equipment.Example:250 ml. glass beaker1 straw150 ml. Lime Water10 g. Baking SodaProcedure: The procedure is a somewhat detailed, step - by - step description of how youconducted your experiment. Example: "After 1 minute, I stirred in the baking soda and timed thereaction 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 istelling you. Example: "Test Plant 3 showed little difference in growth rate as compared to theControl 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 datasupported your hypothesis or not. You may have data that supported part of your hypothesis andnot 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.Resources: One of the most important things for a student to do is recognize the people andresources used in developing and conducting the project. Name the people who offeredknowledge or helped, and list the web sites, retail stores, magazines, books, computer programs,etc. that were used as sources of information or supplies.
