1. Notes – Nature of Science

2. Goal of Science The main goal of science is to understand the world around us and propose explanations for what is observed Nature follows “rules” – the natural laws – scientists want to understand how and why by asking questions and making observations and testing their ideas

3. Science- It’s Everywhere! There are many types of science! Everything you see deals with science in some way! Science involves asking questions and finding out answers just ‘because’ or to make life better! The word science comes from the Latin word scire which means “to know” Not all questions are solved in the same way! The beginning is to figure out FACTS facts -truths about nature facts are not science- they have to relate and work together

4. “Science is built up with facts as a house is with stones, but a collection of facts is not science, any more than a heap of stones is a house!!” Jules Henri Poincare

5. GOAL of Science = UNDERSTAND THE WORLD AROUND US Since we live in the world- we might as well figure it out and UNDERSTAND it! Besides – what better way to get to know the Creator than to understand His creation!

6. 2 Types of Science 1. P ure Science Gathering new info just to do it Adds to body of knowledge (NOT USED for anything purposeful-just is knowledge!) 2. Technology (Applied Science) Practical use of information It is APPLIED to something – solves problems to make life better!

7. 3 Branches of Science 1.Life Science (7 th grade) - studies living things 2.Earth Science (8 th grade) - studies the earth, atmosphere, weather, space 3.Physical Science (9 th grade) - studies matter & energy of non-living things (chemistry & physics)

8. LIFE SCIENCE - deals with living things - Examples zoology – study of animals botany - study of plants genetics – study of DNA of organisms ecology - study of organisms & their relationship to the environment & each other anatomy - study of structure of living things microbiology - study of small living things bacteria & viruses

9. Earth Science -studies the earth, its atmosphere, weather & space Examples: - meteorology – study of the weather - geology – study of the earth -astronomy - study of the universe -hydrology– study of fresh water -seismology – study of earthquakes -paleontology- study of fossils -oceanography – study of the oceans

10. Physical Science - study of matter & energy of non-living things - EVERYTHING is either matter or energy Chemistry – study of matter and how it changes -matter: anything that has mass & volume Physics-study of the different forms of energy and the forces that affect matter Some branches blend: -biochemistry- study of chemical makeup of living things - geophysics – study of the forces that affect the Earth
