Document Summary
Steps: make an observation, ask a question, formulate a hypothesis, design an experiment. Dependent (observe how it responds to the change) Controlled (wants to remain constant-constant variables, can be many) Controlled experiment (two groups differ in one way) control group vs. experimental group.

Structure of matter (anything that takes up space and has mass: ex: air, trees, cement, your desk, kinetic molecular theory-describes the structure & activity of matter, tiny objects in constant motion, different properties, all made up of atoms.
