Summary of Updates
December 2025:
● Introduce chemical formula of baking soda before initial model (and review Lewis Structures) (Lesson 1.1)
● Updated pH interactive, added second interactive, and made adjustments to Lesson 1.3 to explore types of acids building on progression regarding dissociation and hydrogen ions and better align to HS-PS1-6.
● Small update on initial and final model activities and checklists

2/26/25: Reworked order so students make pancakes first, then "make sense" of how baking soda produced gas without immediately going to pH: added in investigations that compare decomposition of baking soda due to heat vs. neutralization with acid
7/6/24: Added in more practice problems and support for stoichiometry for lesson 2.1 and created an additional lesson after this (2.2). This involves 3 new worksheets with practice problems, answer key, and additional scaffolding in classroom slides.
