3 STATES OF MATTER: Solid, Liquid, Gas

Academic Vocabulary— Science, 5-8 (adapted from Building Academic Vocabulary by Robert Marzano.) Provide a student-friendly Students restate in their own Students construct a picture, Students discuss terms with one description, explanation, or words in writing. symbol, or graphic representation another-comparing pictures, example of the term. of the term. descriptions and make additions revisions to notebook entries.

MATTER Matter has mass (a Students discuss, analyze, Matter is anything that has measurement of how much Matter= solid, liquid, or gas compare… add, revise mass and occupies space. matter there is in a body) & notebook entries as Often described in terms of occupies space. It can change necessary. phases (states) of matter according to temperature. because matter can change according to temperature… Phases include solid, liquid, gas.

SOLID Solids are made up of fixed Students discuss, analyze, Atoms are in a fixed position atoms that are tightly compare… add, revise —tightly packed and strongly packed. They can vibrate but notebook entries as attracted to each other. can’t change positions or be necessary. They may vibrate but resist separated. A rock is an separation. Can be changed to example of a solid. liquid or gas phase by adding thermal energy. Examples: rock, shoe, book, etc…

LI QUID Liquids are made of atoms Students discuss, analyze, Atoms are strongly attracted that are closely packed but compare… add, revise but not as much as in a solid. they can change positions. notebook entries as Atoms remain close but are They take the shape of the necessary. free to change positions. container they’re in. Example They take the shape of the is water… container—they flow… May be changed to solid or gas by adding thermal energy. Examples: water, soft drinks, milk, tea, urine, fruit juices, tears, rain, etc…

GAS Gases are made of atoms Students discuss, analyze, Molecules have very little that move around freely and compare… add, revise attraction on each other. have little attraction to each notebook entries as They move freely and are not other (atoms are far apart…). necessary. very dense. They fill the Example is the air in a container they’re in-- adding balloon. thermal energy can change their physical state… Examples: hydrogen, oxygen, nitrogen, water vapor, fizz in carbonated drinks, etc…

Engage students periodically in games and activities that help them add to their knowledge of the terms. Many examples can be found in chapter 4 of Building Academic Vocabulary by Robert Marzano.
