State The QuestionHow, What, When, Who, Which,

Question must be something that you can measure preferable

with a number.

Research (Collect Information)Look it up!Look up information on the internet, in books, magazines and past projects.

concepts3. Know and learn about concepts

Research helps you understand your project

Form Hypothesis

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)

Test Your Hypothesis

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

Record and Analyze Data

Draw ConclusionSummarize how your results support or contradict your original hypothesisWrite in complete sentences

Support conclusion; include key facts from researchState whether results support or contradict hypothesis

Summarize and evaluate experiment

Suggest changes in experimental procedure for further study

Types of VariablesVariable – 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
