Document Summary
The study of the composition, properties, and interactions of matter. Hypothesis: a tentative explanation of observations that acts as a guide for gathering and checking information. Law: summarize a vast number of experimental observations, and describe or predict some facet of the natural world. Once results are consistent, it contributes to a body of knowledge, then a hypothesis becomes a theory or an observation becomes a law. Macroscopic domain:the realm of everyday things that are large enough to be sensed by human sight or touch (ex: spraying bleach on something, a breeze) Microscopic domain: almost always visited in the imagination; some aspects are visible through a microscope (ex. bacteria); others are too small to be seen even with a microscope (ex. atoms) and must be pictured in the mind. Symbolic domain: contains the specialized language used to represent components of the macroscopic and microscopic domains (ex: chemical symbols, chemical equations) Matter: anything that occupies space and has mass.
