Scientists over the centuries found they faced the same problem when it came to sorting out the truth from non truths. To solve the problem, they devised a methodical framework within which to work. This framework is called the scientific method, and it\'s extremely important to solve a problem.

A scientist often credited with being the first to employ the scientific method is Francesco Redi, an Italian physician who lived from 1626 until 1697.

Scientific method requires intelligence, imagination, and creativity.

slide4

What is scientific method?

The scientific method is a tool that helps scientists and the rest of us to solve problems and determine answers to questions in a logical format.

It provides step-by-step, general directions to help us work through problems.

slide5

There are five steps to the scientific method

  • Identify a problem.
  • Research the problem.
  • Formulate a hypothesis.
  • Conduct an experiment.
  • Reach a conclusion.

problem ??? pen torch doesn\'t work

You think back to the last time your pen torch didn\'t work, and you remember that it was because of worn-out batteries.

You guess that worn-out batteries is the reason this time as well

So you get some new batteries from the drawer next to your bed and replace the ones in your pen torch.

Oh! pen torch works.

finished the great book !

slide7

you\'re faced with the problem of not being able to read because your pen torch doesn\'t work, and you\'re not happy about it.

Identify a problem.

You think back to the last time your pen torch didn\'t work, and you remember that it was because of worn-out batteries.

Research the problem.

You guess that worn-out batteries is the reason your pen torch isn\'t working

Formulate a hypothesis.

now, so you get some new batteries from the drawer next to your bed and replace the ones in your pen torch.

Conduct an experiment.

Reach a conclusion.

Oh! Your pen torch works.

Variables

A variable is any factor, trait, or condition that can exist in differing amounts or types.

Independent

Dependent

Controlled

The independent variable is the one that is changed by the scientist. As the scientist changes the independent variable, he or she observes what happens.

The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable.

Experiments also have controlled variables. Controlled variables are quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent variables.
