The Nature of Science Chapter 1 -1 Science 8

Science in Society n What is science? n Science—way or a process used to investigate what is happening around you – Helps solve problems – Helps answer questions

n Is science new? n Science is not new – People throughout history have tried to explain things happening around them

n How do people find answers to questions in daily life? Start with a problem to solve n Look for clues n Find answers n

Using Prior Knowledge n What steps do scientists take to form theories? Use prior experience 2. Test predictions 3. Form theories when predictions have been well tested 1. n More than one time

Using Science & Technology n What can science lead to? n Technology— application of science to make products or tools that people can use – – – Computers Cell phones MP 3 DVD Wii

n What are some resource materials scientists use to find information? n n n Books Newspapers Magazines Videos Web pages

n What scientific skills do scientists use? Observation—what you learn through your senses n Inference—how you explain what you observe n Measurement n Comparing/contrasting n – Alike/different n Classifying – Grouping based on characteristics

n Observation – Use of your five senses • • • What do you see? What do you feel? What do you hear? What do you taste? What do you smell? – Can use instruments • Thermometer, meterstick, balances n Inference – Attempt to explain your observations – Must use accurate data and observations

Observation vs. Inference Observation n Using your five senses n – – – What do you see? What do you feel? What do you hear? What do you smell? What do you taste? Inference n An attempt to explain or interpret obsservations n – What caused what you observed
