3: Physical Science
3.1: Describe how the chemical properties of a substance are defined by the arrangement of atoms and molecules. Draw diagrams to show that atoms may come together as well-defined molecules and also that they may be packed together in large arrays.
Bohr Model of Hydrogen
Bohr Model: Introduction
Electron Configuration
3.2: Diagram or describe a simple chemical change that occurs when two substances, elements or compounds react and produce one or more different substances. Use examples to explain that when a chemical change occurs in a closed system, the total mass of the system remains unchanged. Explain how chemical reactions involve the exchange and sharing of electrons between the atoms of the reactants.

3.3: Describe the change in movement of atoms and molecules in solids, liquids and gases that occurs with a change in state. Recognize that although such a change in state may occur, atoms and molecules are in constant motion and do not change their internal structure.

Temperature and Particle Motion
3.4: Use examples to explain that when the transfer of energy occurs from one system to another, the total energy before the transfer equals the total energy after the transfer. Describe the transfer of heat energy across space or through a material, and how it involves the collision of atoms within the material.

4: Earth and Space Science
4.1: Describe the cause and history of the movement of earth?s lithospheric plates and how these movements shape earth?s surface. Predict which geologic events and features present will be present at plate boundaries.
Plate Tectonics
5: Life Science
5.1: Identify that instructions specifying the traits of an organism are found in the DNA packaged as chromosomes inside its cells. Recognize that DNA is the same in every cell of an organism. Describe how traits are inherited by the passage of chromosomes from one generation to another.

Human Karyotyping
Microevolution
Natural Selection
RNA and Protein Synthesis
5.2: Differentiate between traits that are acquired and those that are inherited. Explain how a particular environment selects for traits that increase survival and production of off spring by individuals bearing those traits. Explain how not all traits that are selected for are necessarily beneficial for long-term survival of the species.
