Science is observing, studying and experimenting to find the nature of things. • The two main branches are social science and natural science.
Life science • biology
Physical science • Chemistry • Physics
Earth science • Geology • Meteorology
Integrated Physics and Chemistry is a comprehensive course that unites two of the fundamental sciences.
Technology is the application of science • An example of technology is an airplane http://vod.esc11.net/videos/v2.2/25229/sec15709_300k.mp4
Scientific theory is a tested, possible explanation of a natural event. • An example is the Big Bang Theory http://vod.esc11.net/videos/v2.2/11303/chp895689_300k.mp4
Scientific law is a summary of an observed natural event. • An example is the Newton’s Universal Law of Gravitation http://vod.esc11.net/videos/v2.2/1007/chp6678_300k.mp4
Scientists make laws and theories based on observations and measurements
Qualitative information is based on an observation—it’s QUALITY • Quantitative information is based on mathematical equations and QUANTITY • Scientific models are used to simplify very big, very small or very complex ideas.
Theories and laws are NOT absolute. • An example is the Geocentric Model
