Scientific Method

Scientific Method is series of steps that is used to conduct an experiment.

The steps are:

1. Purpose2. Research3. Hypothesis4. Experiment5. Analysis6. conclusion

Scientific Method

Purpose:Why is the lab is being

conducted?

What is trying to be discovered?

What is the intent of the lab?

The purpose gets the lab started…with the problem

Research:Provides background

information based on the purpose.

Hypothesis is based off of this research.

Extensive research is vital for better understanding of the lab.

Scientific Method

Hypothesis:Educated guess on what

the outcome of the experiment will be…

Based on knowledge that you know and on what you find from your research.

Experiment:A series of actions that

will prove the hypothesis correct or incorrect, and it must be controlled.

The experiment contains an independent (the variable that is manipulated) and dependent variable (relies on independent variable).

Scientific Method

Analysis:This is to state the

outcome of the experiment briefly.

A graph or chart, according to the data, has to be shown to prove the outcome of the experiment.

Also, any calculations, or qualitative data is shown in this area of the experiment.

Conclusion:This part of the

experiment is to explain what happened, why, and what could be a possible future experiment.

This also explains the independent and independent variables, as well as analyzing the data.

GraphingGraphing

We will cover terms including

• Independent variable

• Dependent variable

• Qualitative data

• Quantitative data

• Examples of appropriate graphing

GraphingGraphing

Independent Variable• Definition: a factor in an

experiment that a scientist purposefully changes; also known as a manipulated variable.

• The independent variable is graphed on the y-axis.

Dependent Variable• Definition: A factor in an

experiment that a scientist wants to observe, which may change in response to the independent variable: also known as the responding variable

• The dependent variable is graphed on the x-axis.

GraphingGraphing

Qualitative Data• Definition: Data that is

descriptive and involves characteristics that can not usually be described with numbers.

• Examples of qualitative data include color, shape, and mental or physical states.

Quantitative Data• Definition: Data that is

described by numbers, obtained by counting or measuring.

• Examples of quantitative data include percentages, ratios, measurements, and averages.
