We’ve got it all for you!

The Scientific Method Øa body of techniques for investigating phenomena, acquiring new knowledge or correcting and integrating previous knowledge

Scientific Method PROBLEM OBSERVATIO N HYPOTHESIS EXPERIMENTATION THEORY

Schematically, the scientific method can be shown as follows: Observations (world of experience) Scientific Law (a summary of what have been observed) Hypothesis (a guess explaining observations) Theory (tested hypothesis, not permanent, can be modified)

Science Process Skills: • Observing • Classifying • Measuring • Inferring • Predicting • Communicating • Using number relationships
