1. The Nature of Science
What do scientists do?

2. Scientists….
Investigate by conducting experiments both in the laboratory and in the field
Plan experiments before conducting experiments
Observe results of experiments
Test results by repeating experiments to see if they get the same results several times

3. Natural Science
The study of the natural world and the interactions of everything in the natural world
Areas of natural science are
Earth Science – meteorology, geology, archeology, astronomy, etc.
Life Science – zoology, botany, microbiology, ecology
Physical Science – chemistry the study of matter and its interactions and physics the study of energy and forces

4. Social Science The study of people and their interactions
Sociology, anthropology, history,

5. Technology vs pure science
Pure science is learning about science for the sake of learning
Technology is using scientific knowledge to make life better.

6. Scientific Law vs Scientific Theory
A scientific law tells what happens
The law of gravity says what goes up must come down.
It doesn’t tell why something happens only tells what happens.
Scientific theories explain why things happen the way they do.
Evolution is a theory it explains how living things change over long periods of time.
Theories and Law are always being tested and can be changed anytime new information proves they are wrong.

7. Mathematics can describe physical events
Qualitative descriptions use words to describe physical events
A ball will fall to Earth when you let go.
Quantitative descriptions can be mathematical equations which describe an event with formulas or numbers
A = l x w or the ball has a mass of 45 kg.

8. Scientific Models
A representation of an object or event that makes it easier to study and understand
Models can be 3 dimensional, they can be a diagram, a computer program, or a map or picture.
