Lab: Exploratorium's Ocean Acidification In A Cup

in

Time: 60 min

Goal: Model an ocean-atmosphere interaction and explain how carbon dioxide gas diffuses into water, causing the water to become more acidic.

Includes:

  • Lab worksheet (instructions, questions, etc.)

  • Slides for Exploratorium’s Ocean Acidification In A Cup

  • Videos with timers, safety review, and lab procedure demo, applications to coral bleaching, etc.

Note to self: (To Do) add inquiry-driven portion for students to devise questions together (requires more chemistry than mere carbon cycling stations activity)
