**8th Grade: Chemistry **


Key Idea 3: Matter is made up of particles whose properties determine the observable characteristics of matter and its reactivity. Key Idea 4: Energy exists in many forms, and when these forms change energy is conserved.** ||~  || Compound, Mixture, Heterogeneous Mixture, Homogeneous Mixture, Solution, Colloid, Solubility, Solute, Solvent, Density, Weight, Mass, Volume** ||  ||

 * = **Standards** || * //**Performance Indicator 3.1: Observe and describe properties of materials, such as density, conductivity, and solubility.**//
 * **3.1a: Substances have characteristic properties. Some of these properties include color, odor, phase at room temperature, density, solubility, heat and electrical conductivity, hardness, and boiling and freezing points.**
 * **3.1b: Solubility can be affected by the nature of the solute and solvent, temperature, and pressure. The rate of solution can be affected by the size of the particles, stirring, temperature, and the amount of solute already dissolved.**
 * **3.1g: Characteristic properties can be used to identify different materials, and separate a mixture of substances into its components. For example, iron can be removed from a mixture by means of a magnet. An insoluble substance can be separated from a soluble substance by such processes as filtration, settling, and evaporation.**
 * **3.1h: Density can be described as the amount of matter that is in a given amount of space. If two objects have equal volume, but one has more mass, the one with more mass is denser.**
 * **3.1i: Buoyancy is determined by comparative densities.**
 * //**Performance Indicator 3.3: Develop mental models to explain common chemical reactions and changes in states of matter.**//
 * **3.3a: All matter is made up of atoms. Atoms are far too small to see with a light microscope.**
 * **3.3b: Atoms and molecules are perpetually in motion. The greater the temperature, the greater the motion.**
 * **3.3c: Atoms may join together in well-defined molecules or may be arranged in regular geometric patterns.**
 * **3.3d: Interactions among atoms and/or molecules result in chemical reactions.**
 * **3.3e: The atoms of any one element are different from the atoms of other elements.**
 * **3.3f: There are more than 100 elements. Elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances. Few elements are found in their pure form.**
 * **3.3g:** **The periodic table is one useful model for classifying elements. The periodic table can be used to predict properties of elements (metals, nonmetals, noble gases).**
 * //**Performance Indicator 4.2: Develop mental models to explain common chemical reactions and changes in states of matter.**//
 * **4.2e: Temperature affects the solubility of some substances in water.** ||  ||
