What is Science Ch. 1.1 (pgs 2 6)

• SCIENCE a system of knowledge and the
  methods you use to find that knowledge.
• Science begins with questions and often ends with
  discovery.
• Science requires observing and experimenting to
  determine the nature of something.

2
Technology

• Technology (Applied Science) is the
  application of science for practical
  purposes to meet human needs (Ex
  Biotechnology, Computer Sci.)
• Science and technology are interdependent.
  Advances in one lead to advances in another.

BIG IDEAS IN SCIENCE

• SPACE TIME The universe is soooo BIG very
  OLD (13.7 billion yrs.)
• MATTER CHANGE Matter has mass volume and is
  made up of atoms. Atoms are made up of protons,
  neutrons, electrons
• FORCES MOTION Forces cause a change in motion
• ENERGY Energy can change forms, but can never
  be destroyed
