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.
