1^st Six Weeks

SC-HS-1.1.1

Students will classify or make generalizations about elements from data of observed patterns in atomic structure and/or position on the periodic table.

The periodic table is a consequence of the repeating pattern of outermost electrons.

DOK 2

SC-HS-1.1.2

Students will understand that the atom’s nucleus is composed of protons and neutrons that are much more massive than electrons. When an element has atoms that differ in the number of neutrons, these atoms are called different isotopes of the element.

SC-HS-1.1.3

Students will understand that solids, liquids and gases differ in the distances between molecules or atoms and therefore the energy that binds them together. In solids, the structure is nearly rigid; in liquids, molecules or atoms move around each other but do not move apart; and in gases, molecules or atoms move almost independently of each other and are relatively far apart. The behavior of gases and the relationship of the variables influencing them can be described and predicted.

2^nd Six Weeks

SC-HS-4.6.2

Students will:

·     predict wave behavior and energy transfer;

·     apply knowledge of waves to real life phenomena/investigations.

Waves, including sound and seismic waves, waves on water and electromagnetic waves, can transfer energy when they interact with matter. Apparent changes in frequency can provide information about relative motion.

3^rd Six Weeks

SC-HS-1.1.1

Students will classify or make generalizations about elements from data of observed patterns in atomic structure and/or position on the periodic table.

The periodic table is a consequence of the repeating pattern of outermost electrons.

DOK 2

SC-HS-4.6.6

Students will understand that heat is the manifestation of the random motion and vibrations of atoms.

SC-HS-1.1.7

Students will:

·     construct diagrams to illustrate ionic or covalent bonding;

·     predict compound formation and bond type as either ionic or covalent (polar, nonpolar) and represent the products formed with simple chemical formulas.

Bonds between atoms are created when outer electrons are paired by being transferred (ionic) or shared (covalent). A compound is formed when two or more kinds of atoms bind together chemically.

DOK 2

4^th Six Weeks

SC-HS-1.1.4

Students will understand that in conducting materials, electrons flow easily; whereas, in insulating materials, they can hardly flow at all. Semiconducting materials have intermediate behavior. At low temperatures, some materials become superconductors and offer no resistance to the flow of electrons.

SC-HS-1.1.5

Students will explain the role of intermolecular or intramolecular interactions on the physical properties (solubility, density, polarity, conductivity, boiling/melting points) of compounds.

The physical properties of compounds reflect the nature of the interactions among molecules. These interactions are determined by the structure of the molecule including the constituent atoms.

DOK 2

5^th Six Weeks

SC-HS-1.1.8

Students will:

·     explain the importance of chemical reactions in a real-world context;

·     justify conclusions using evidence/data from chemical reactions.

Chemical reactions (e.g., acids and bases, oxidation, combustion of fuels, rusting, tarnishing) occur all around us and in every cell in our bodies. These reactions may release or absorb energy.

DOK 3

SC-HS-1.1.6

Students will:

·     identify variables that affect reaction rates;

·     predict effects of changes in variables (concentration, temperature, properties of reactants, surface area and catalysts) based on evidence/data from chemical reactions.

Rates of chemical reactions vary. Reaction rates depend on concentration, temperature and properties of reactants. Catalysts speed up chemical reactions.

Students will:

·     explain the importance of chemical reactions in a real-world context;

·     justify conclusions using evidence/data from chemical reactions.

Chemical reactions (e.g., acids and bases, oxidation, combustion of fuels, rusting, tarnishing) occur all around us and in every cell in our bodies. These reactions may release or absorb energy.

DOK 3

SC-HS-4.6.5

Students will describe and explain the role of carbon-containing molecules and chemical reactions in energy transfer in living systems. 

Living systems require a continuous input of energy to maintain their chemical and physical organization since the universal tendency is toward more disorganized states. The energy for life primarily derives from the Sun. Plants capture energy by absorbing light and using it to break weaker bonds in reactants (such as carbon dioxide and water) in chemical reactions that result in the formation of carbon-containing molecules. These molecules can be used to assemble larger molecules (e.g., DNA, proteins, sugars, fats). In addition, the energy released when these molecules react with oxygen to form very strong bonds can be used as sources of energy for life processes.
