3Question Examples: Not so great: Great: Which brand of battery is the best?Are mice smart?How do plants grow?Great:Can you estimate how high a tree is by measuring it’s shadow?Which brand of battery last longer?Does a ball roll faster on grass or dirt?

6HypothesisBased on the research you have done, you will be writing an answer or solution – your best educated guess – to your question. This is what you think will solve the problem Restate the problem in a declarative sentence that would answer your question/problem
7Hypothesis Do not begin with I think or I predict "If _____[I do this] _____, then _____[this]_____ will happen." (Fill in the blanks with the appropriate information for your own experiment.)Your hypothesis should be something that you can actually test, what's called a testable hypothesis. In other words, you need to be able to measure both "what you do" and "what will happen.""If I put fenders on a bicycle [having fenders is the independent variable], then they will keep the rider dry when riding through puddles [the dependent variable is how much water splashes on the rider]."
8VariablesControlled variables: These are the things that are kept the same throughout your experiments.Independent variable: The one variable that you purposely change and test.Dependent variable: The measure of change observed because of the independent variable. It is important to decide how you are going to measure the change.
9Hypothesis Check ListWhat Makes a Good Hypothesis?For a Good Hypothesis, You Should Answer "Yes" to Every QuestionIs the hypothesis based on information contained in my research?Yes / NoDoes the hypothesis include the independent and dependent variables?Have you worded the hypothesis so that it can be tested in the experiment?
10MaterialsType a detailed list of the items you needed to complete your experiments.Be specific about the amounts used.List in a columnInclude quantity and size
11Materials Check ListWhat Makes a Good Materials List?For a Good Materials List, You Should Answer "Yes" to Every QuestionHave you listed all necessary materials?Yes / NoHave you described the materials in sufficient detail?
12Procedure List all of the steps used in completing your experiment. Remember to number your steps.
13Procedures Check ListWhat Makes a Good Experimental Procedure?For a Good Experimental Procedure, You Should Answer "Yes" to Every QuestionHave you included a description and size for all experimental and control groups?Yes / NoHave you included a step-by-step list of all procedures?Have you described how to the change independent variable and how to measure that change?Have you explained how to measure the resulting change in the dependent variable or variables?Have you explained how the controlled variables will be maintained at a constant value?Have you specified how many times you intend to repeat the experiment (should be at least three times), and is that number of repetitions sufficient to give you reliable data?The ultimate test: Can another individual duplicate the experiment based on the experimental procedure you have written?If you are doing an engineering or programming project, have you completed several preliminary designs?
14Test (an organized process used to test the hypothesis) Follow the procedures step by stepCollect dataConduct experiment at least three times for accuracy
15Test Check ListWhat Makes a Good Science Experiment?For a Good Science Experiment, You Should Answer "Yes" to Every QuestionDid you take detailed notes about your observations and record them in your laboratory notebook?Yes / NoDid you collect your data using a data table?Were you consistent, careful, and accurate when you made your measurements?Were you careful to insure that your controlled variables remained constant so as not to affect your results?If you ran into any unexpected problems, did you adjust your experimental procedure accordingly?
16VariablesControlled variables: These are the things that are kept the same throughout your experiments.Independent variable: The one variable that you purposely change and test.Dependent variable: The measure of change observed because of the independent variable. It is important to decide how you are going to measure the change.
17Variables Check List What Makes for Good Variables? For Good Variables, You Should Answer "Yes" to Every QuestionIs the independent variable measurable?Yes / NoCan you change the independent variable during the experiment?Have you identified all relevant dependent variables, and are they all caused by and dependent on the independent variable?Are all dependent variable(s) measurable?Have you identified all relevant controlled variables?Can all controlled variables be held at a steady value during the experiment?
18Data/ObservationsIt is easier to understand the data if it is put into a table or graph.Make sure all data is clearly labeled.Add photos of your experiments.
19BAR GRAPH – This is the most common type for science fair projects BAR GRAPH – This is the most common type for science fair projects. You may select a bar graph when your independent variable is qualitative (categories) or quantitative (numbers).
20Line graphs are great for showing changes in the dependent variable over time or distance along a certain period.
21PIE CHART – Pie charts are good for projects that have qualitative independent variables and have generated data that can be expressed as percentages of the total.
22Graph Check ListWhat Makes for a Good Graph?For a Good Graph, You Should Answer "Yes" to Every QuestionHave you selected the appropriate graph type for the data you are displaying?Yes / NoDoes your graph have a title?Have you placed the independent variable on the x-axis and the dependent variable on the y-axis?Have you labeled the axes correctly and specified the units of measurement?Does your graph have the proper scale (the appropriate high and low values on the axes)?Is your data plotted correctly and clearly?
23ConclusionBrief summary of what you discovered based on the results of your experiments. You need to indicate whether or not the data supports the hypothesis and explain why or why not. Include what would you do if you retested. Begin with “The results show that the hypothesis is supported or not supported.”
24Conclusion Check ListWhat Makes for Good Conclusions?For Good Conclusions, You Should Answer "Yes" to Every QuestionDo you summarize your results and use it to support the findings?Yes / NoDo your conclusions state that you proved or disproved your hypothesis? (Engineering & programming projects should state whether they met their design criteria.)If appropriate, do you state the relationship between the independent and dependent variable?Do you summarize and evaluate your experimental procedure, making comments about its success and effectiveness?Do you suggest changes in the experimental procedure and/or possibilities for further study?
