Learn about the states of matter - solids, liquids, and gases. Explore how the movement of particles determines their state, their characteristics, and examples of each. Discover how particles change state and take part in interactive activities to grasp concepts better.

What does state of matter mean? • Matter= atoms • How much particles move determine their state • Can be: • Solids • Liquids • Gases
Solids • Definite volume • Definite shape • Vibrate but do not move • Only exception: • Ice- particles farther a part than in liquid
Liquid • Definite volume • Not definite shape • Particles attracted to each other, but can move around
Gases • No definite shape • No definite volume • Particles not close to each other and can move around • Space can increase or decrease depending on temperature
Examples of your own • Provide an example, similar to the fish bowl on pg.68-69 of a solid, liquid, and gas • Be prepared to share with class
Particles changing state • Solid to liquid- melting • Liquid to solid (particles slowing down)- freezing • Fill out chart on pg. 70 for other changes
Name that matter • After each statement is read, go to the corner you think represents that type of matter • Can be solid, liquid, gas, or none of these • Can have sharp corners • Does not have mass • Exerts pressure on all sides of container • Has definite volume, but no definite shape • The particles that make this up are completely still • Formed when something melts • Particles vibrate in place • Particles move freely
Put it together • With your group, explain how a hot air balloon works. Think about the states of matter and density.
