Experiments are performed all around us everyday. Whether they're done to find out if a cancer curing medication works or to find out how fast water evaporates at certain temperatures, experiments are constantly performed. However, what separates a simple experiment from a professionally done experiment is the use of the Scientific Method.
The Scientific Method is a series of organized steps to which an experiment is done. The Scientific Method helps you plan, predict, research, conclude and maybe even publish your findings. The Scientific Method will make your experiment more organized, easy to interpret and learn from.
In this Instructable, I will help guide you through each step using a sample experiment. You will also learn the significance of each step as I break the Scientific Method down.
The steps to the Scientific Method are:
1) Pose a Testable Question.
2) Conduct Background Research.
3) State your Hypothesis.
4) Design Experiment.
5) Perform your Experiment.
6) Collect Data.
7) Draw Conclusions.
8) Publish Findings (optional).
Step 1: Understand the Sample Experiment
Our sample experiment is going to be the rate of sugar cubes dissolving in water at different temperatures. Basically, I will drop sugar cubes into cups of water with different temperatures and time how long it takes the sugar cubes to "disappear" (dissolve).
Step 2: Pose a Testable Question
The Testable Question is the question that the experiment is based on. Every experiment is performed because someone questions or is curious about something. So, all the Testable Question really does, is pose that burning question.
In the sample experiment, our Testable Question is:
Does water temperature affect the rate at which sugar cubes dissolve?
