Bhopal Gas Tragedy STEM Case Study

Investigate the world's worst industrial chemical disaster with this comprehensive, no-prep 6-page printable STEM Case Study Packet! Designed specifically for middle and high school classrooms, this multi-day unit provides an immersive, highly informative look at the tragic 1984 Bhopal Gas Tragedy. By combining chemical reaction kinetics, environmental plume thermodynamics, plant safety diagnostics, applied mathematics, and corporate ethics, this resource transforms a landmark industrial catastrophe into a rich, interactive learning experience.

Throughout this unit, students explore critical secondary STEM concepts—including methyl isocyanate (MIC) synthesis, exothermic runaway reactions, chemical scrubber mechanics, toxic gas dispersion plume physics, and industrial safety regulations—in an accessible, highly engaging format.

What’s Included in this 6-Page Deep-Dive Packet:

• Page 1: Historical Case Study & Technical Breakdown

  Features a detailed historical narrative of the December 2–3, 1984 disaster at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, India. Students examine methyl isocyanate (MIC) synthesis, water ingress exothermic runaway kinetics, failed safety scrubbers, flare tower maintenance shutoffs, and atmospheric inversion plume dispersion before answering targeted comprehension check questions.

• Page 2: Day in the Life Scenario Challenge

  Students step into the shoes of a Chief Chemical Safety Inspector at midnight on the night of the leak. In this realistic roleplay assignment, they analyze real-time storage tank pressure spikes, evaluate temperature runaway logs, trace vent gas scrubber bypasses, and navigate emergency plant evacuation protocols.

• Page 3: Hands-On Unplugged Simulation & Applied Math

  Brings chemical engineering math into the classroom with clear, step-by-step calculations. Students compute exothermic reaction heat generation against refrigeration cooling capacities, calculate toxic gas plume dispersion concentration in parts per million (PPM), and model population exposure risk radius formulas.

• Page 4: Engineering Ethics & Workplace Dilemma

  Explores corporate cost-cutting versus safety regulations. Students analyze double-standard safety policies between US and foreign subsidiary plants, the decision to turn off refrigeration systems to save $30 per day, undermanned maintenance staffing, and corporate accountability.

• Page 5: Redesign Brief & Innovation Lab

  A creative blueprinting challenge where students act as chemical engineers designing "Bhopal Chemical Synthesis Plant V-2." Applying inherently safer design (ISD) principles, they incorporate micro-quantity storage tanks, redundant automated caustic soda scrubbers, pilot-ignited emergency flare towers, and fence-line community siren networks.

• Page 6: Teacher Answer Key & Scoring Rubric

  Includes complete, step-by-step solutions for all narrative comprehension questions and mathematical calculations, along with a clear 10-point grading rubric to streamline assessment for the design blueprint assignment.
