1 Physics – The Basic Science Topics Scientific Method Identify Variables Scientific Attitude Science & Technology Activities Class Work

2 Physics – The Basic Science Science used to be called Natural Philosophy Unanswered Questions --- > Answers --- > SCIENCE Science Today Living things Non Living things Biology Geology Zoology Astronomy Botany Chemistry Physics Physics: Nature of things --- > Motion, forces, energy, matter, heat, sound and light Mathematics: The Language of Science

3 Scientific Method Recognize the problem Make an educated guess – hypothesis – about the answer Predict the consequences of the hypothesis Perform experiments to test predictions Formulate the simplest general rule: hypothesis + prediction + experiment Hypothesis: If _______ then _________ because______ Galileo Galilei (1564 – 1642)

4 Variables Manipulated (or Independent) Variable Responding (or Dependent) Variable Controlled Variables (or Controls) In a controlled experiment these variables must be measurable In this experiment, which are the different variables ?

5 The Scientific Attitude Fact: Agreement of competent observers of the same phenomenon Hypothesis: Educated guess -- > Fact if demostrated by experiment Laws or Principles: Tested hypothesis over and over Theory: Synthesis of a large body of information + well-tested hypothesis about certain aspects of the natural world. Theories undergo changes !!! Atomic Theory

6 Science and Technology Science: Method of answering theoretical questions Technology: Method of solving practical problems Science is a way of knowing Technology is a way of doing
