Challenger Disaster STEM Case Study

Investigate the 1986 Challenger disaster with this 6-page STEM packet covering O-ring physics, polymer chemistry, launch telemetry, and ethics.

Engage your middle and high school students with a comprehensive, hands-on deep dive into one of the most pivotal engineering and managerial failures in modern aerospace history. This complete printable unit bridges aerospace engineering, materials science, and organizational ethics to teach elastomer thermal glass transition temperature, solid rocket booster field joint physics, hot gas blow-by erosion, launch decision protocols, and safety culture.

What’s Included in this 6-Page Unit Packet:

Page 1: Historical Case Study & Technical Breakdown – Full narrative of the January 28, 1986 launch, solid rocket booster (SRB) field joint mechanics, synthetic rubber O-ring elasticity loss at 36°F, joint rotation, flame plume ignition of the external tank, and comprehension check questions.

Page 2: Day in the Life Scenario Challenge – Roleplay assignment where students step into the shoes of a NASA Mission Director at Kennedy Space Center, analyzing pre-launch freezing telemetry, teleconference warnings from Morton Thiokol engineers, and launch go/no-go protocols.

Page 3: Hands-On Unplugged Simulation & Applied Math – Step-by-step math calculations comparing O-ring resilience recovery times (milliseconds vs. seconds) across ambient temperatures, joint gap expansion pressure (PSI), and gas blow-by leakage rates.

Page 4: Engineering Ethics & Workplace Dilemma – Critical thinking exercise exploring the fatal teleconference, Roger Boisjoly’s engineering warnings, schedule pressure from delays, management override quotes, and whistleblower ethics.

Page 5: Redesign Brief & Innovation Lab – Creative blueprinting assignment where students design “Space Shuttle SRB Field Joint V-2,” incorporating an overarching capture latch flange, dynamic heated seal channels, a third redundant O-ring, and automated thermal sensors.

Page 6: Teacher Answer Key & Scoring Rubric – Complete answer key for all analytical questions and math calculations, along with a 10-point grading rubric for evaluating student blueprints on Page 5.
