Chapter 1 Notes
What is Science
I. Science
- science comes from the latin word scire “ to know”
A.Theories and Laws
*Theory- most logical explanation of events
*Law- theory that has been tested many times, and is generally accepted by scientist
B.Scientific Method* a systematic approach to solving a
problem (pp13)
1. State the problem
2. Gather information
3. Form hypothesis
4. Perform experiments
5. Record and analyze data
6. State conclusion
Scientific Method cont.
* hypothesis- educated guess
* Variable(I. & D.)- the one factor that is being tested
* Experimental setup- the part that contains
the I. variable
* Control setup- same as ES, but does not contain the I. variable
Scientific Method cont
* Data- recorded observations and measurements
- in order to become a law, the results must be able to be reproduce many times.
Branches of Physical Sciencepp 6
* Chemistry- study of what substances are made of and how they change and combine
* Physics- study of forms of energy and the laws of motion
- prefixes
II. Scientific Measurements pp 15-19
* Metric System- standard system of science
A. Length - basic unit is meterB. Volume - basic unit is liter/
1ml=1ccC. Mass- basic unit is kilogram
Scientific Measurements
D. Density- mass/volume
E. Temperature- Celsius
F. Dimensional Analyst- worksheet
III. Tools of MeasurementA. Length
B. Mass
C. Volume
D. Temperature
