The Scientific Method

Not just for scientists!

Adapted from http://panpipes.net/edit6200/

What is it? The scientific method is a logical sequence of steps that

people use to identify, test, and answer a problem. It is broken down into six steps:

1) State the problem.2) Form a testable hypothesis.3) Design an experiment.4) Collect and analyze data.5) Draw conclusions.6) Communicate results.

Taking a closer look… Choosing a question or problem to solve:

Make sure it’s realistic and that you can gather the necessary resources.

When possible, choose a topic that really interests you. Your question must include both a manipulated (independent)

variable and responding (dependent) variable. Safety first! Make it new and interesting to YOU!

Taking a closer look…

Creating a testable hypothesis: “I predict that…” Include a statement that shows cause and effect. (If,

then, because.) It must address the manipulated and responding

variables. Right or wrong does not matter!

Taking a closer look…

Designing an experiment: Carefully decide what your constants will be. Decide what materials you will need. Decide how you will measure your constants and your

variables. List all procedures in order.

Taking a closer look…

Collect and analyze data: Always keep constants and your manipulated variable in

mind and follow your procedures. Organize your raw data in a table.* Use your data table to create a graph for your

conclusion. (More to come!)

Taking a closer look… Drawing conclusions:

Restate your problem and hypothesis. Summarize your procedures. Explain how the MV affected the RV.

(What does the graph show?) Explain whether or not the results

supported your hypothesis. If not, why? Future experiments.

Communicate Results
