In this 11-36 class period bundle, students unpack 4 phenomena to explore concepts related to acids, pH, chemical reactions, and stoichiometry. Students are introduced to the mole and molar mass (and conversions), explore chemical changes, solubility, and intermolecular forces, and learn about limiting reactants and excess reactants, molar ratios in chemical reactions, and theoretical vs. actual yield.
 
Why is there such a wide range in the number of class periods needed? Because this is often completed near the end of the school year and teachers are often short on time, our unit planner provides multiple paths that can be taken for this unit. These paths range widely in the number of class periods required.
 
This unit is intended to be used for introductory high school chemistry classes.
 
Science practices are heavily emphasized and include developing models, asking questions, analyzing and interpreting data, engaging in arguments from evidence, and obtaining, evaluating, and communicating information.
 
Phenomenon 1: Ricotta: Precipitation & Rates of Reactions • 2-7 Class Periods 
Students explore chemical changes, precipitation, and rates of chemical reactions by investigating the formation of curds and making fresh ricotta.
 
Phenomenon 2: Paneer: Introduction to the Mole & Molar Mass • 4-6 Class Periods
Students are introduced to the mole and explore the importance of molar mass by investigating possible substitutions in a paneer recipe. This also encourages students to apply concepts they learned in HS: Unit 1 (Flavor).
 
Phenomenon 3.1:Baking Soda Module 1: Acid/Base Reactions • 3-6 Class Periods
Students explore how baking soda works through multiple labs, recipe analysis, and investigations to unpack the chemical reaction between baking soda and acids.
 
Phenomenon 3.2: Baking Soda Module 2: Stoichiometry & Limiting Reactants • 4-8 Class Periods
Students investigate limiting reactants, excess reactants, and molar ratios in chemical reactions by exploring what occurs when different amounts of baking soda are added to a pancake recipe.
 
Phenomenon 4 (Assessment) Baking Powder: Stoichiometry & Limiting Reactants • 3-5 Class Periods
Students further explore concepts learned in the baking soda module by investigating what baking powder is made of and different formulations of baking powder.
