Document Summary

Chapter 1 chemical tools: experimentation and measurement. Chapter 1. 1: the scientific method in a chemical context. The scientific method: scientific method is a general approach to research; an iterative process involving formulation of questions and conjectures based on observations, experimental design, and analysis of results. Visualizing chemical behavior with molecular models: molecular models are used to develop a theory and visualize structure-function relationships; they"re simplified versions of how atoms are connected and reveal their three dimensional arrangement. In order for experiments to be reproduced, substances used must be fully described in detail (including amounts, volumes, temperatures etc. ), so it"s important to have a way to measure things, but the sizes of units can be inconveniently large or small. Scientific notation is used when working with very small or large numbers, and provides a consistently structured measurement with units. Mass amount of matter in an object.
