Matter+Unit+Learning+Targets

__//** Learning Target: **//__
 * // Kinetic Molecular Theory is used to describe how particles of matter move and how it relates to temperature of an object. //**

· ** Identify thermal energy as the random motion (kinetic energy) of molecules or atoms within a substance **


 * ·Use the kinetic molecular model to explain changes in the temperature of a material **


 * · Using the Kinetic Theory model, illustrate and account for the physical properties (i.e., shape, volume, malleability, viscosity) of a solid, liquid, or gas in terms of the arrangement and motion of molecules in a substance **


 * · Use the Kinetic Theory model to explain changes in the volume, shape, and viscosity of materials in response to temperature changes during a phase change **


 * · Predict the effect of energy transfer on the physical properties of a substance as it changes to or from a solid, liquid, or gas (i.e., phase changes that occur during freezing, melting, evaporation, boiling, condensation) **

__//** Learning Target: **//__
 * // Pure substances have unique physical and chemical properties. //**


 * · Identify elements (unique atoms) and compounds (molecules or crystals) are pure substances that have characteristic properties **


 * · Describe the physical and chemical properties (e.g., magnetic attraction, conductivity, melting point and boiling point, reactivity) of pure substances (elements or compounds) (e.g., copper wire, aluminum wire, iron, charcoal, sulfur, water, salt, sugar, sodium bicarbonate, galena, quartz, magnetite, pyrite) using appropriate senses and tools **

**· Identify more than 100 known elements (unique atoms) exist that may be combined in nature or by man to produce compounds that make up the living and nonliving substances in the environment (Do NOT assess me**morization of the **Periodic Table)**

__//** Learning Target: **//__
 * // Both energy and matter are conserved (not //** **// lost) during physical and chemical changes. //**


 * · Identify the evidence of different energy transformations (e.g., explosion of light, heat, and sound, temperature change, electrical charge) that may occur as chemical energy is released during a chemical reaction **


 * · Provide evidence that mass is conserved during a chemical change in a closed system (e.g., vinegar + baking soda, mold growing in a closed container, steel wool rusting) **


 * · Explain that the amount of matter remains constant while being recycled through the rock cycle **
