4 Environmental impact Chemical processes must be understood at the molecular level • Atoms and molecules are invisible Atoms and molecules are invisible •How do we know the nature of these invisible atoms and molecules? Scientific method 1. Make observations (collect data) 2. Make predictions (formulate hypothesis) 3. Carry out experiments to test the prediction (test hypothesis) Observation Hypothesis Experiment Law Theory (model) Hypothesis Experiment Modify theory as needed
