Scientific Method

This is a website about the Scientific Method. This will be a scientific method in an experiment.

First we use PHIC

It means

P roblem
H ypothesis
I nvestigation
C onclusion

The first thing to do is find the problem. A problem is what you want to know. ( Usually a ? ) .

Than you make a hypothesis, ( a guess ). A hypothesis is what do you think will happen. You should tell the why.

After the hypothesis you need to investigate. If you don't investigate you won't get a complete answer. Investigation is what you do to test. Document the results.

After the investigation you have to document the results. You have to find the control, independent variable, and dependent variable.The control is the part of the experiment that remains the same. The independent variable is the part of the experiment that changes. There should be only 1 per experiment. The dependent variable is change caused by the independent variable.

In the Bubble Time experiment the control, independent variable, and the dependent variable are.......

Control- Beginning Mass of Gum
Chew Time
Person Chewing Gum

Independent Variable- Brand of Gum

Dependent Variable- Gram Mass


When you investigate and get your results you start with your conclusion. A conclusion is what happened. Backed up with results.
