  1. “What is science?”

  2. “What is Science?” • Science • A way of learning about the natural world through observations and logical reasoning (Scientific Method) • Scientific Inquiry • The ongoing process of discovery in science • Physical Science • The study of matter and energy (Chemistry & Physics) • Observation • Using one or more of the five senses to gather information Intro

  3. “What is Science?” (cont.) • Data • Facts, figures and other evidence learned through observations • Inference • A logical interpretation based on observations and prior knowledge • Hypothesis • A possible explanation for a set of observations or answer to a scientific question Intro

  4. “What is Science?” (cont.) • Variable • Any factor that can change in an experiment • Independent variable • Dependent variable • Control variable • Scientific Law • Scientific Theory Intro

  5. Basic Skills Notes Think Like a Scientist • Observing - Using one of your five senses to gather information • Inferring - interpreting an observation • Predicting - making an inference about a future event based on current evidence or past experience • Classifying - grouping together items that are alike in some way Intro

  6. Think Like a Scientist (cont.) • Making Models - representation of a complex process • Communicating - process of sharing ideas and information with other people Intro

  8. Measurements (cont.) • Length - meter (m) • Volume - liter (L) • Mass - gram (g) • Temperature - Celsius (C) • Time - sec (s) Intro

  9. Converting units • top/bottom method • Examples & Activities Intro

  10. Conducting a Scientific Investigation (Scientific Method) • Posing Questions • Developing a hypothesis • Designing an experiment • Interpreting Data • Drawing conclusions Intro

  11. What’s the Point?Technology • Using science principles to solve practical problems • New Technology in your life? • Other recent Technologies Intro
