Experiments: highly controlled procedures designed to generate observations that can confirm or refute a hypothesis. Scientific law: a brief statement that summarizes past observations and predicts future ones. Atomic theory: proposed by chemist john dalton proposed that matter is composed of small, indestructible particles called atoms. Matter: anything that occupies space and has mass.
