What is Science? Chapter 1
Science: • The observation and investigation of the natural world
Branches of Science • Earth and Space Science • Life Science • Physical Science
PhysicalScience • The study of matter and energy
Physical Science a. Physics: The study of energy and its effects on matter
Physical Science b. Chemistry- the study of the structure of matter and the changes it undergoes due to energy.
Two types of science • pure science • applied science
Pure Science (Observation) • Studying a subject to learn more about it
2 types of Observations: Qualitative observation: describe features of the object (color, shape, smell, etc) Quantitative observation: describe an amount of a feature (involves numbers)

Applied Science (Technology) • turning observations into inventions • Examples: • cars, eyeglasses, etc. Technology
Turning observations into inferences • Take out a piece of notebook paper • Write down as many observations about each slide as you can. • Make an inference about what you think the next few slide will show. http://micro.magnet.fsu.edu/primer/java/scienceopticsu/powersof10/index.html
Theory – a well-tested explanation for observations or results Ex. Theory of how dinosaurs became extinct
Scientific Law – describes an observed pattern in nature Ex. Law of gravity
What does a scientist do? • Make Observations • Ask Questions, Be Curious • Solve Problems
Problem Solving or Looking for the answer ?
Solve the Problem (3 steps) • 1) Gather Information • 2) Plan a Strategy • 3) Make a Prediction
1) Gather Information • Look for any patterns • Has anyone else had the problem • Have you ever had the problem
2) Plan a Strategy • Figure out the potential solutions • Can you test the potential solutions one at a time
3) Make a Prediction • Keep it simple at first • It should be testable
