Scientific Method A way to ask and answer scientific questions by making observations and doing experiments.
How, What, When, Who, Which, Why, or Where… Start with question. Question must be something that you can measure preferable with a number.
Look it up! Look up information on the internet, in books, magazines and past projects. 1. Identify keywords in the question 2. Brainstorm keywords and concepts 3. Know and learn about concepts Research helps you understand your project
Hypothesis: An educated guess by you, planned out and supported by facts.
If (IV), then (DV – trend). I base my hypothesis on these facts. 1. 2. 3. 4. (this one my be personal)
Material: List of materials and equipment Procedure: Written Steps for doing the experiment
Your experiment tests whether your hypothesis is true or false. It is important for experiment to be a fair test. Change only one factor at a time while keeping all other conditions the same. REPEAT if time permits.
Once experiment is complete, collect measurements and analyze them to see if hypothesis is supported or not. Make sure to label all graphs and tables Include units of measurements Use graphs, tables and/or charts to show data
Summarize how your results support or contradict your original hypothesis Write in complete sentences Support conclusion; include key facts from research State whether results support or contradict hypothesis
Summarize and evaluate experiment Suggest changes in experimental procedure for further study
Variable – any factor, trait or condition that exists in differing amount or types Independent variable – one variable that is changed Dependent variable – how it responds to the change made by the independent variable Controlled variable – remains constant
