1. What is Science Ch. 1.1 (pgs 2 – 6) SCIENCE = a system of knowledge and the methods you use to find that knowledge. questionsScience 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.

3. Branches of Science NATURAL SCIENCE PHYSICAL SCIENCE EARTH & SPACE SCIENCE LIFE SCIENCE PHYSICS: Study of matter & energy & interactions b/w the 2 through forces & motion CHEMISTRY: Study of matter’s structure, composition, properties, & rxns Geology: Study of the origin, history, structure or Earth ASTRONOMY: Study of the universe beyond Earth BIOLOGY: Study of living things Zoology - Animals Ecology: Interxns b/w living things & their environment GENETICS: DNA, Heredity, & Evolution METEOROLOGY: Weather & Atmosphere OCEANOGRAPHY – Oceans & coastal geol Branches over lap in many cases. Ex: Biochemistry; Astrobiology; Geophysics

4. Careers in Earth Science Geologists Seismology: Monitor faults & Earthquakes Petrology: “Hard Rocks” Look for oil deposits; Research how mountains/rock formation form Volcanology: Volcanoes Hydrogeology: Ground water sources Sedimentology: Soil quality, paleoclimates, etc. Marine geology: processes that change ocean basins & continental shelves. Coastal geologist: How beaches change, sand transport

5. Careers in Earth Science Meteorology & Climatology Meteorolgist – weather forecasting Climatologist – gathering data and working with models regarding climate change Paleoclimatogist: ancient climates Astronomy Astronomer Planetary Scientist Cosmologist – Universe, galaxies, matter & energy Astrobiology: life on other planets/planetary environments

6. 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
