Integrated Science- Year 1 Sample Flowchart for Concept Instructional Sequence

The Earth is a unique system that supports life.

What is the structure of the atom?

IA

Atomic and molecular structure determines physical characteristis of rocks in lithosphere. (C1e)

Composition and structure of matter determine characteristics.

Instruction will include: Subatomic particles Nuclear symbols (reading cells in the Periodic Table) Bohr models Atomic dimensions (relate atoms nucleus electrons)

How does the atomic structure affect the organization of the Periodic Table? Instruction will include: Periodic Table: families, groups, periods) Specific periodic families Periodic trends (atomic size, metallic character, valence electrons, ionization energy, electronegativity Position on periodic table corresponds with atomic number and mass (C1a) * Identification of lanthanide, actinide, transactonide; use of nuclear accelerators Identification of alkali metals, alkaline earth metals, transition metals; ionization energy, electronegativity, relative sizes of ions and atoms (C1c) Periodicity of physical and chemical properties and atomic structure. in synthesis (C1f) Identification of metals, semimetsls, non-metals, halogens (C1b) Instruction will include: Types of bonds (ionic, covalent, metallic) Number of valence electrons bonding Electronegativity differences and type of bond How does the location of an element of Periodic Table affect its interactions with other elements? Periodic table: number of electrons available for bonding (C1d) Bonds, electrostatic forces determine biological, chemical, and physical properties of matter. Formation of molecules through covalent and ionic bonds (C2a) Instruction will include: Chemical and physical properties of each of the three types of rocks (igneous, sedimentary, metamorphic) Relationships between perperties and formation of each type of rock Types of plate boundaries Rock types found at each type of plate boundary How do interactions between elements affect the physical and chemical properties of more complex systems (e.g., rocks)? Three kinds of plate boundaries— geological structures that result (E3b) Properties of rocks based on conditions of formation—including plate tectonics
