Standard 3.2 What does it look like to demonstrate profciency on this standard? Organizing Data Students organize data that: ● Identifes the products and reactants, including their chemical formulas and the arrangement of their outermost (valence) electrons Identifying Relationships Students use models to analyze the data and identify and describe relationships in the datasets, including: ● The patterns of reactivity (e.g., the high reactivity of alkali metals) at the macroscopic level as determined by using the periodic table ● The outermost (valence) electrons and the relative electronegativity of the atoms that make up both the reactants and the products of the reaction based on their position in the periodic table Interpreting Data Students use the analyzed data to make a claim: ● Predicting the outcome of a simple chemical reaction, not included in their data Standard 3.4 What does it look like to demonstrate profciency on this standard? Representation Students identify and describe the relevant components of the system using mathematical representations including: ● Quantities of reactants and products of a chemical reaction in terms of atoms, moles, and mass ● Molar mass of all substances involved in the reaction ● Use of balanced chemical equation(s) The mathematical representations may include: ● Numerical calculations ● Graphs ● Other pictorial depictions of quantitative information Students identify (the content claim) that atoms, and therefore mass, are conserved during a chemical reaction. Mathematical modeling Given a chemical reaction, students use the mathematical representations to
