An Introduction to Science
and the Scientific Method

What is science?
• It is the knowledge covering
truths or the operation of
general laws obtained and
tested through the scientific
method.
• This means it is about studying
and testing stuff.

Branches of Science
• There are three branches of
science. They all cover
something different.
• Physical science
• Earth and Space science
• Life Science

Physical Science
• Atoms, molecule,
elements, and
compounds
• Energy, motion,
forces, and work
• Heat, light, sound,
and electricity

Earth and Space
Science
• Soil, rocks, and minerals
• Fossils
• Solar system

Life Science
• Plant, animals, and cells
• Human body, diseases,
and cures
• Life, growth, and death
• How all life is related to
other life and to the
whole planet

The Scientific Method
• Scientists use a certain series of
steps in order to test something.
• This is called the scientific method.
• Identify
• Observe
• Hypothesis
• Experiment
• Conclusion

Identify a Problem
• The first step in the scientific
method is identifying a problem.
• Ask yourself a question about why
something is like it is or what
would happen if I did this.

Make an Observation
• What is happening or what is
different?
• Why is this happening or why is
it different?

Form a Hypothesis
• A hypothesis is an educated
guess.
• This is happening or this is
different because…

Test the Hypothesis
• This means do your experiment.
• You experiment, then make
your observations and collect
your data.

Form a Conclusion
• Look at your data and
observations and form a
conclusion about your
hypothesis.
• My hypothesis was correct or
incorrect because…
