Why Learn Chemistry? Required for my major Safety (don’t mix bleach and ammonia) Health (diet, medicine) Informed citizens needed to vote or act on current issues (environmental pollution, global warming, etc.) Satisfaction of a deeper understanding of the material world

Conceptual Tools of Science Natural Law: Verifiable Universal Truth. A succinct summary of many observations. Observations: passive (astronomy) and active (experimental chemistry) measurements Hypothesis and Theory: A model of how we understand more complicated things in terms of simpler things. Theory allows us to predict new things.

Ideally: make observations, formulate hypotheses, test hypotheses with new observations or experiments, formulate theory, modify theory, etc. until a well developed and useful model occurs. In Practice: Science can be very messy
