This document provides an introduction to physical science. It defines physical science as the study of physics and chemistry. Physics is defined as the study of the physical world, including motion, energy, and other concepts like mass, weight, force, and energy. Chemistry is defined as the study of the composition and changes of matter. The document also discusses the scientific method, scientific theories, laws and principles, models, and the differences between pure science and technology.

4. Chemistry
The study of:
 the composition (make-up) of matter
 the changes that matter undergoes

5. Physics
The study of the physical world
including motion, energy, light,
electricity, magnetism, sound etc.

6. Physics Concepts include
 Mass: the amount of matter in an
object.
 Weight: The force with which the
earth pulls on an object.
 Force: A push or a pull
 Energy: Ability to do work(to apply
a force and move an object.)

7. Scientific Method
 Recognize a problem
 Hypothesis- an educated guess,
must be testable.
 Observation -measurement, data
collection (experiment)
 Conclusion

8. Scientific Theory
 A well- tested explanation for a
set of observations.

9. Scientific Law or Principle
 Describes and summarizes an observed
pattern in nature without attempting to
explain it.
 A hypothesis that has been repeatedly
tested and not contradicted.
 Change or are abandoned when
contradicted.

10. Scientific Models
 A representation of an object or an
event, that helps us visualize and
understand them.

11. Demo
 Catching a falling ruler

12. Law or Principle
 A hypothesis that has been
repeatedly tested and not
contradicted
 Change or are abandoned when
contradicted

13. Scientific Fact
 Observation
 May change

14. Science and Technology
 Pure Science 
Done for the sake of knowledge
 Applied Science (Technology)
Done with a purpose of solving a
problem. Has an application.
