In this 18-26 class period bundle, students unpack 4 phenomena to explore chemical reactions and texture:
Yeast Breads & Proofing (Introduction to chemical reactions; predicting and identifying reactants and products)
Popping Boba (further review of chemical reactions, double dispacement chemical reactions)
BBQ & Combustion (combustion reactions, energy)
Assessment: Aluminum & Copper Chloride Investiation
 
This unit is intended to be used for introductory high school chemistry classes.
Students are introduced to chemical reactions, collision theory, rates of chemical reactions, chemical equations, and types of chemical reactions through phenomena that include yeast bread (naan), pancakes and baking soda, ricotta, and popping boba.
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: Yeast Bread (5-7 periods)
Students are introduced to chemical reactions and explore conservation of matter, chemical equations, factors that affect rates of cellular respiration, and collision theory.
Phenomenon 2: Baking Soda (5-6 periods)
Students investigate what is needed and produced in chemical reactions involving baking soda. They learn more about acid/base neutralization reactions and apply what they have learned about chemical reactions to identify the products produced.
Phenomenon 3: Ricotta (5 periods)
Students further explore chemical reactions with acids and see another sign of a chemical reaction- the formation of a precipitate. They also have opportunities to easily explore rates of chemical reactions through a simple student-designed experiment.
Phenomenon 4: Popping Boba (Assessment; 5-6 period)
Students explore a double displacement chemical reaction and make sense of the products by applying their understanding of chemical reactions. They further make sense of gel formation by applying concepts from Unit 1: Flavor.
