Scientific Method Galileo Galilei (1564 – 1642) • 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______

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 ?

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

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
