What is science? Science is a process of trying to understand the world by making models (or theories) which have predictive power. It usually involves: Observing Looking for patterns (which can be clues to underlying laws) This may involve - Sorting - Classifying - Measuring Suggesting an explanation (hypothesis) which explains all the observations made so far AND predicts new ones Making an experiment or collecting more data which tests the prediction (If the experiment fails) Suggesting another hypothesis, and trying another experiment.... Telling others what you have discovered. Science is a way of trying not to fool yourself” -Richard Feynman
