Chapter 1: The Chemical World

explains causes of observed behaviors

learning to analyze and interpret data is an important scientific skill?

What is composed of atoms?

1 of the 3 things that chemistry requires

a way of learning that emphasizes observation and experimentation

statement that summarizes past observations and predicts future ones is called scientific law

highly controlled observations designed to validate or invalidate hypotheses

often visualized using graphs or images

key characteristics of the scientific method

all matter is composed of small, indestructible particles called molecules

summary of observed behaviors

everything that we can hold or touch is made of?

first step in acquiring scientific method

experiments do NOT determine validity of laws, hypotheses or theories

Antoine Lavoisier studied the burning of substances in closed containers. What is this called? - Read about in textbook.

measurement of some aspect of nature

in a chemical reaction, matter is neither created nor destroyed

the science that tried to understand how matter behaves & how atoms/molecules behave?

who discovered the atomic theory

a tentative interpretation or explanation of the observations
