High School Science

• Convert number of moles to amount of particles (moles → particles, particles → moles) Reactions: • Balance a chemical equation (be able to show number of atoms are conserved and mass is conserved) • Be able to identify types of reactions (single & double replacement, combustion, synthesis, & decomposition) • Describe common evidence of chemical changes (color change, gas formation, precipitate, heat &/or light production) • Compare properties of reactants to products • Connect common chemical reactions to the real world Stoichiometry: • The coefficients in a balanced chemical equation can represent amounts of moles • Using quantitative data, support the law of conservation of mass • Convert moles of one compound to moles of another compound using mole ratios • Conversions needed (mass to moles to moles, moles to moles to mass)

Math Skills

Literacy Standards

RST-7: Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words. RST-8: Assess the extent to which the reasoning and evidence in a text support the author's claim or a recommendation for solving a scientific or technical problem. WHST-1: Write arguments focused on discipline-specific content . WHST-1a: Introduce precise claim(s), distinguish the claim(s) from alternate or opposing claims, and create an organization that establishes clear relationships among the claim(s), counterclaims, reasons, and evidence. WHST-1b: Develop claim(s) and counterclaims fairly, supplying data and evidence for each while pointing out the strengths and limitations of both claim(s) and counterclaims in a discipline-appropriate form and in a manner that anticipates the audience's knowledge level and concerns. WHST-1c: Use words, phrases, and clauses to link the major sections of the text, create cohesion, and clarify the relationships between claim(s) and reasons, between reasons and evidence, and between claim(s) and counterclaims. WHST-1d: 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-1e: Provide a concluding statement or section that follows from or supports the argument presented.

• Ratios/proportions • Converting between different units • Forming ratios between products and reactants • Describing ratios between compounds in a reaction • Calculating quantities of products or reactants (in mass, moles, volume, etc.) • Scientific Notation
