Back to School STEM Activity: Index Card Tower Challenge (BTS1)
By Innovative Middle School STEM
🗼 Back to School STEM Activity: The Index Card Tower Challenge (BTS1) Kick off the school year with an engaging, low-prep engineering team-building challenge! The Index Card Tower Challenge (BTS1) challenges middle school students to think like civil engineers and architects by building the tallest possible free-standing tower using only 20 index cards. No tape, glue, staples, or paperclips allowed! Students must fold, notch, roll, and interlock their cards to create structural strength from simple shapes while working within a strict 15-minute build window. 📦 What’s Included in This 2-Page Packet: • Page 1: Student Mission Card & Blueprint: • Real-world civil engineering scenario and structural challenge framing. • Clear material limits and constraints box (Zero fasteners, 10-second free-standing rule, 15-minute time limit). • Dedicated Engineering Blueprint & Structural Plan sketching zone for pre-build team brainstorming. • Page 2: Testing Log & Scientific Reflection: • Structured Data Testing Table: Track trial strategies, tower heights (in cm), and 10-second stability passes across 3 prototype runs. • Applied Math Connection: Calculate average tower height across trials, plus unit conversions from centimeters (cm) to millimeters (mm) and meters (m). • Engineering & Reflection Questions: Analyze geometric strength (triangles vs cylinders vs boxes), failure modes, iteration fixes, and team communication dynamics. 📐 Core STEM Skills Covered: • Structural Engineering & Lo
