Title: The Scientific Method


1
The Scientific Method
  • Making sure science is done right! ?

2
What is the scientific method?
  • A process that is used to find answers to
    questions about the universe around us.

3
Is there only one scientific method?
  • No, there are several ways of stating the steps
    of the scientific method.
  • Some versions have more steps, while others only
    have a few.
  • However, they all begin with the identification
    of a problem or a question to be answered based
    on observations of the world around us and
    provide an organized method for conducting and
    analyzing experiments

4
What is a hypothesis?
  • A hypothesis is an educated guess based on
    observations and your own knowledge of the topic.

5
What is data?
  • It is information gathered during an experiment.

6
Steps of the Scientific Method
7
  • Identify The Problem
  • What do you want to know or explain?
  • Use observations you have made to write a
    question that addresses the problem or topic you
    want to investigate.

8
  • Form A Hypothesis
  • What do you think will happen?
  • Predict the answer to your question or the
    outcome of the experiment.

9
How to Write a Hypothesis
  • A hypothesis is an educated guess based on
    observations and your knowledge of a topic.
  • Most of the time a hypothesis is written like
    this
  • If I do this, then this will happen.
  • Your hypothesis should be something that you can
    actually test, what we call a testable
    hypothesis. In other words, you need to be able
    to measure both what you do and what will
    happen.

10
  • Create An Experiment
  • How will you test your hypothesis?
  • Develop a procedure for a reliable experiment and
    address safety rules.

11
What Are Variables?
  • The independent, or manipulated variable, is a
    factor thats intentionally varied by the
    experimenter.
  • The dependent, or responding variable, is the
    factor that may change as a result of changes
    made in the independent variable.

12
What are Controls?
  • In a scientific experiment, the control is the
    group that serves as the standard of comparison.
  • The control group may be a no treatment" or an
    experimenter selected group.
  • The control group is exposed to the same
    conditions as the experimental group, except for
    the variable being tested.

13
What Are Constants?
  • The constants in an experiment are all the
    factors that the experimenter attempts to keep
    the same.

14
  • Perform An Experiment
  • Follow the steps in your procedure to perform
    your experiment.
  • Record all data and observations.

15
What Are Trials?
  • Trials refer to repeated groups that are exposed
    to the same conditions in an experiment.

16
  • Analyze The Data
  • Is the data reliable?
  • Does your data and observations from the
    experiment support your hypothesis?

Go Back to Perform an Experiment
YES
NO
Modify Experiment Rewrite the procedure to fix
flaws
NO
Go To Communicate the Results
Is your data inaccurate or the experiment flawed?
YES
17
  • Communicate The Results
  • Write a conclusion that summarizes the important
    parts of your experiment and the results.
