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 Recognize a problemDevelop a HypothesisPredict ConsequencesFormulate RulesRefine the HypothesisPublish Results Develop Experiments

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 Consequences Creative Leap 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 ☛ A powerful idea/axiom has many consequences ☛ The scientific process begins when the scientist develops consequences based on the idea/axiom ☛ 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 Life SciencePhysical Science Biology Zoology Botany Physics Chemistry Geology Science

Physics – A Scientific World View The Basic Science – Physics  Physics is the most basic of all the sciences Particles, atoms, energy, forces, …… Molecules, reactions, equilibrium,…… Physics Chemistry Biology Genes, cells, organs, growth,……

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 Scientific World View Common Sense

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  Hypothesis – An educated guess that is only presumed to be factual until demonstrated by experiment Scientific hypotheses must be testable Hypothesis Scientific Attitude

Physics – A Scientific World View  Laws or Principles – Hypotheses being tested repeatedly and not contradicted Law/Principle Scientific Attitude

Physics – A Scientific World View  Theory – A synthesis of a large body of information that includes well-tested hypotheses about certain aspect of the natural world Theory Scientific Attitude

Physics – A Scientific World View  Concept – An intellectual framework that is part of a theory encompasses the overriding idea that underlines various phenomena Concept Scientific Attitude

Physics – A Scientific World View  Not appealing to authority, personal preferences, popularity or selecting partial facts STOP Scientific Attitude
