BHS Secondary Science

quantum, wavelength, emit, absorb, spectrum, energy level, photon, frequency, valence electron, metal, non-metal, metalloid, malleable, conductive, periodic table Essentials Extension (If Time Permits) Eliminate Light: waves, energy and photons • Relationship between wavelength, frequency and energy • Bohr Model: How light is emitting from an atom: electrons absorb energy, energy level transitions result in light emission. • energy absorbed and released is in “discrete” units (quanta) • Lab evidence to make connections between absorbing energy and releasing light; and using results to identify elements (flame tests and/or spectrum tubes) • Relate color of light to energy of that light • Particle vs. wave nature of light Quantum Mechanical Model : • what is it: electrons are located in regions based on probability (orbits vs. orbitals) • Energy levels, sublevels and orbitals: s,p,d and f sublevels/orbitals; shapes; # of electrons in each sublevel/orbital • Electron configuration (up to argon) Periodic Table: • determining # of valence electrons • organization: families (groups); periods; order of increasing atomic number • types of elements: metals, non-metals, metalloids; properties and location on periodic table • Calculating wavelength, frequency and energy • Photoelectric effect • Heisenberg uncertainty principle • Electron configuration with d and f; orbital notation and noble gas configuration • Lewis dot diagram for an element • History of periodic table development • Electron affinity • NA

• generalized trends: atomic radius; electronegativity and ionization energy • reactivity and properties of elements (in a family): valence electrons

Math Skills

Literacy Standards

• Solve a one variable equation • Use appropriate units • Scientific notation • Identify patterns on a graph

RST-4: Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific or technical context relevant to grades 9-10 texts and topics. RST-5: Analyze the structure of the relationships among concepts in a text, including relationships among key terms. WHST-2d: Use precise language and domain-specific vocabulary to manage the complexity of the topic and convey a style appropriate to the discipline and context as well as to the expertise of likely readers. WHST-2e: Establish and maintain a formal style and objective tone while attending to the norms and conventions of the discipline in which they are writing. WHST-2f: Provide a concluding statement or section that follows from and supports the information or explanation presented.
