Scientific Reasoning in Chemistry: Observations, Models, and Fair Tests
A strip of magnesium gives off a bright light. Your notebook can record that observation immediately. Explaining the light takes another step: you need evidence about which substances were present and what changed. Keeping the observation separate from its explanation makes your chemistry more careful. Scientific reasoning connects observations with explanations that can be checked. […]
