TN READY REVIEW TASK 1
Review- Matter and It’s Interactions
Success Criteria
ONCE YOU ARE COMPLETED WITH TASK ONE IN ITS ENTIRETY YOU MUST GET YOUR WORK SIGNED OFF ON BY YOUR TEACHER
Go to the next clean page in your comp book
Label that page "Day 1 Review- Matter and It’s Interactions"
Write this vocabulary in your composition book (MUST BE SIGNED BY TEACHER)
•Element: chemically simplest substances. Cannot be broken down into other elements. All matter is made of these substances.
•Matter: a physical substance which can occupy space and has mass.
•Physical Property: Properties that are observable and measurable without changing the identity of the substance-melting point, boiling point, color,density, etc.
•Chemical Property: Property that describes a substance based on it’s ability to change into a new substance- combustibility, ability to oxidize (rust), flammability, reactivity
•Electron: subatomic particle with a negative charge used in bonding. Located on the outside of the atom.
•Proton: subatomic particle with a positive charge. Determines the identity of the element. Located in the center of the atom. Makes up half of the mass
•Neutron: subatomic particle with a neutral charge. Located in the center of the atom. Makes up half of the mass.
•Ion: a charged atom. It is charged because the number of protons doesn’t equal the number of electrons.

Molecule: 2 or more ATOMS bonded together. Can be the same element.
•Compound: 2 or more ELEMENTS bonded together.
•Are all compounds considered a molecule? Are all molecules a compound?

7.PS1.3 Classify matter as pure substances or mixtures based on composition.
•Pure Substance: substance made of only one kind of element or molecule. Pure substances cannot be separated without creating new substances.
•Mixtures: substances made of more than one kind of element or molecule mixed together. Mixtures can be separated into the different pure substances that make them up.
CLASSIFY THE FOLLOWING A A SUBSTANCE OR A MIXTURE
7.PS1.6 Create and interpret models of substances whose atoms represent the states of matter with respect to temperature and pressure.
COMPLETE THE PHET SIMULATION
WRITE AND ANSWER THE QUESTIONS IN YOUR COMP BOOK
•What happens to the amount of heat energy (the temperature) as you move from a liquid to a solid?
•If I wanted to use pressure to change the state of matter, what would I do to change from a liquid to a solid?
