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…
