Chemistry as a Science

Compounds of carbon, life, human body, plant, proteins, carbohydrates.

Compound in periodic table, non-life, minerals

Systematized body of knowledge based on nature and the facts of life gathered through keen observation (research) and experimentation. A process by which knowledge is produced.

• Used to solve problems. • Way we do research • Make observations of nature. • Derive a hypothesis or build a model in response to observations. • Construct experiments to bolster or refute hypotheses or models.

Scientific Method

Pick something your curious about

Educated/Intelligent Guess

Plan to test hypotheses, observations, see if it’s right or wrong

record of experimental results

review data and draw a conclusion

Explain results and analysis to determine if hypothesis is right or wrong

systematic approach to research

Tentative Explanation for a set of observations (tentative answer). It is tested then modified in repeat

Facts, Concepts, Theories and Laws

chemical or chemist laws like laws in physics (Been proven in most cases/true in cases.)

a concise statement of a relationship between phenomena that is always the same under the same conditions. (it is possible to break the law)

is a unifying principle that explains a body of facts and/or those laws that are based on them (can change). Is not proven

Forms when iron is exposed to oxygen

Rust is

does not rust but will turn brownish/yellowish overtime
