Stoichiometry: Mole Ratios, Limiting Reactants, & Percent Yield Scaffolded Phenomena-Based Lesson: The Industrial Haber-Bosch Ammonia Synthesis and Percent Yield Presentation | Chemistry | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Scaffolded Phenomena-Based Lesson in the high school Chemistry (grades 9–12) chapter Stoichiometry: Mole Ratios, Limiting Reactants, & Percent Yield, built around the phenomenon The Industrial Haber-Bosch Ammonia Synthesis and Percent Yield. This scaffolded version adds sentence frames and extra supports for students who need them. It is sold separately from the other two parts of the set.

Complete the set: Stoichiometry: Mole Ratios, Limiting Reactants, & Percent Yield Scaffolded Phenomena-Based Lesson: The Industrial Haber-Bosch Ammonia Synthesis and Percent Yield Teacher Discussion Guide; Stoichiometry: Mole Ratios, Limiting Reactants, & Percent Yield Scaffolded Phenomena-Based Lesson: The Industrial Haber-Bosch Ammonia Synthesis and Percent Yield Student Response Sheet. Original version: Stoichiometry: Mole Ratios, Limiting Reactants, & Percent Yield Phenomena-Based Lesson: The Industrial Haber-Bosch Ammonia Synthesis and Percent Yield Presentation.
