# Matter Outline

 MATTER MATTER   PHYSICAL PROPERTIES Everything is made up of matter. The formal definition is anything that has mass and takes up space Can be measured or observed c. Match the property to the definition below: Mass the concentration of matter in an object Weight the amount of matter in an object Volume measure of the pull of gravity on an object Density the amount of space an object takes up II. Mixtures and Solutions a. A bowl of cereal and milk is an example of a mixture. That’s a combination of two or more different kinds of matter, each of which keeps its own physical properties. b. In a solution the particles of two or more substances are evenly distributed. c. When a substance can be dissolved in another substance (like sugar in water) we call this solubility. III. Changes in State a. The three stages of matter are solid, liquid and gas. b. Draw the arrangement of the particles in each state of matter and describe the speed of their movement as well as how close together they are using the diagram below. gas, moving very fast, & really far apart liquid, faster moving, & spread apart Solid, slow moving, & close together c. When heat is added to a substance, the particles vibrate faster and move apart. d. When heat is removed from a substance, the particles vibrate slower and move closer. IV. Physical and Chemical Changes a. When a physical change occurs the matter may look different, but it doesn’t change. b. When a chemical change occurs a new substance may form. c. List three ways to know that a chemical change may have occurred. gas produced, light, and heat. d. Draw circles around chemical changes & underline physical changes below: i. cutting a piece of paper into small pieces ii. boiling water iii. a nail rusting iv. freezing water e. The chemical property of combustibility describes substances that result in flame or burning. f. The ability of a substance to react chemically is reactivity. V. Conservation of Matter a. Matter cannot be created nor destroyed. b. In class we dissolved Alka Seltzer in a bottle of water. A gas was produced. We caught the gas in a balloon. Though a new substance was formed (the gas) the total mass didn’t change. VI. Atoms and Electrons a. The atomic number refers to the number of protons in the nucleus of an atom. The number ofprotons also determines what kind of element an atom is. b. The element oxygen has 8 protons in its nucleus. All atoms that have 8 protons in the nucleus are oxygen atoms. c. Be able to label the diagram of an atom. (see notes) VII. Metals a. Match the property to its definition by drawing a line: Malleable electricity and heat travel easily through metals Ductile shiny Conductor used as a wire Luster able to be hammered or rolled VIII. Compounds and the Periodic Table a. A compound is different from an element because a compound has more than one type of element in it. b. The Periodic Table has elements arranged in order of increasing atomic number.
