Physics Lesson 1 A Scientific World View Eleanor Roosevelt High School Chin-Sung Lin DoNow: Determine what’s inside the bottle If the current technology cannot open the bottle, how can you find out what’s inside? Discuss it with your partner and write down 3 innovative ways DoNow: Determine what’s inside the bottle Experiments Physics – A Scientific World View What is Science? Scientific Method & Process Role of Physics – The Basic Science Goal of Physics – A World View Scientific Attitude Criteria of Physics Models & Laws Science, Technology and Society What is Science? Physics – A Scientific World View What is Science? Discover and study nature’s rules Physics – A Scientific World View What is Science? A body of knowledge The method to produce it Body of Knowledge Methods Scientific Method Physics – A Scientific World View Scientific Method Galileo Galilei & Francis Bacon are the principal founders of the scientific method Physics – A Scientific World View During the DoNow exercise, which steps have we taken to determine the contents of the bottle? Discuss it with your partner and share them with the class. Physics – A Scientific World View Scientific Method Physics – A Scientific World View Scientific Method Observe Develop Experiments Recognize a problem Formulate Rules Develop a Hypothesis Refine the Hypothesis Predict Consequences Publish Results Physics – A Scientific World View Scientific Method Effective in gaining, organizing & applying new knowledge The method is only a guideline to a good scientific practice Physics – A Scientific World View Scientific Method Einstein’s view of scientific processes Idea/Axiom Creative Leap Consequences The Real World Physics – A Scientific World View Scientific Method Einstein’s view of scientific processes ☛ A scientist makes a creative leap based on intuition to explain physical phenomena ☛ The scientific process begins when the scientist develops consequences based on the idea/axiom ☛ A powerful idea/axiom has many consequences ☛ Test these consequences against the real world Role of Physics Physics – A Scientific World View The Basic Science – Physics Science grew out of natural philosophy Physics – A Scientific World View The Basic Science – Physics Branches into life & physical sciences Science Life Science Physical Science Biology Physics Zoology Chemistry Botany Geology Physics – A Scientific World View The Basic Science – Physics Physics is the most basic of all the sciences Biology Genes, cells, organs, growth,…… Chemistry Molecules, reactions, equilibrium,…… Physics Particles, atoms, energy, forces, …… Goal of Physics Physics – A Scientific World View The Goal of Studying Physics To create a scientific world view Physics – A Scientific World View The Goal of Studying Physics World view – A shared set of ideas that explain how the material world operates Physics – A Scientific World View The Goal of Studying Physics Scientific world view vs. Common sense – sometimes the ideas might appear to be contrary to common sense Common Sense Scientific World View Physics – A Scientific World View The Goal of Studying Physics Scientists use instruments to extend the range of human sensations Scientific Attitude Physics – A Scientific World View Scientific Attitude Fact – A close agreement by competent observers who make a series of observations of the same phenomenon Fact Physics – A Scientific World View Scientific Attitude Hypothesis – An educated guess that is only presumed to be factual until demonstrated by experiment Scientific hypotheses must be testable Hypothesis Physics – A Scientific World View Scientific Attitude Laws or Principles – Hypotheses being tested repeatedly and not contradicted Law/Principle Physics – A Scientific World View Scientific Attitude Theory – A synthesis of a large body of information that includes well-tested hypotheses about certain aspect of the natural world Theory Physics – A Scientific World View Scientific Attitude Concept – An intellectual framework that is part of a theory encompasses the overriding idea that underlines various phenomena Concept Physics – A Scientific World View Scientific Attitude Not appealing to authority, personal preferences, popularity or selecting partial facts STOP Physics – A Scientific World View Scientific Attitude Review Hypotheses being tested repeatedly and not contradicted Law/Principle Physics – A Scientific World View Scientific Attitude Review An educated guess that is only presumed to be factual until demonstrated by experiment Hypothesis Physics – A Scientific World View Scientific Attitude Review An intellectual framework that is part of a theory encompasses the overriding idea that underlines various phenomena Concept Physics – A Scientific World View Scientific Attitude Review A synthesis of a large body of information that includes well-tested hypotheses about certain aspect of the natural world Theory Physics – A Scientific World View Scientific Attitude Review A close agreement by competent observers who make a series of observations of the same phenomenon Fact Criteria of Physics Ideas & Laws Physics – A Scientific World View Scientific Method Criteria of good scientific ideas ☛ As general as possible ☛ As simple as possible Physics – A Scientific World View Scientific Method Criteria of a physics law ☛ Account for the known data ☛ Make Testable predictions ☛ Have a scientific basis Science, Technology & Society Physics – A Scientific World View Science, Technology & Society Science vs. Technology – Targets Questions about Nature Problems of the World Physics – A Scientific World View Science, Technology & Society Science vs. Technology – Goals Answer Theoretical Questions Solve Practical Problems Physics – A Scientific World View Science, Technology & Society Science vs. Technology – Methods Find Relationships Develop Tools & Procedures Physics – A Scientific World View Science, Technology & Society Science vs. Technology – Results Scientific Theories Engineering Solutions Summary – A Scientific World View What is Science?
