Thanksgiving STEM Activity: Mayflower Cargo Float Challenge (THX01)

Bring Archimedes' Principle, buoyant force vectors, water volume displacement (1g = 1mL), center of gravity stability, hull geometry optimization, and structural efficiency ratio math to life with the Thanksgiving STEM Activity: Mayflower Cargo Float Challenge (THX01)! Designed for Middle School Physical Science, Physics, Naval Engineering, Math, and STEM classes across Grades 6–8, this 3-page, print-ready seasonal lab packet challenges students to engineer aluminum foil vessels capable of carrying maximum cargo mass across water basins.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-PS2-2 Forces & Motion, MS-ETS1-2 Engineering Design Solutions), key fluid mechanics physics concepts, testing basin setup instructions, math troubleshooting tips, and a full teacher answer key.

• 🚢 Page 2: Student Mission Card & Blueprint

  Hooks students with a naval architecture scenario to design stable cargo-carrying vessels inspired by historic transatlantic ships. Includes material constraints (aluminum foil sheets, wooden craft sticks or drinking straws, masking tape, testing water basin, pennies or metal washers for payload) and a dedicated schematic sketching zone to diagram hull draft depth, surface area displacement, and center of mass balance.

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured lab data table tracking dry vessel mass in grams, total cargo payload mass supported in grams, and failure mode observations (capsizing vs. swamping) across 3 testing trials. Includes an applied math section to calculate Structural Efficiency Ratios (Cargo Mass Supported / Vessel Mass), followed by reflection questions analyzing buoyant force balance, waterline displacement, and hull shape stabilization.

Educational Value & Key Benefits:

• Hands-On Seasonal Physics: Connects displaced fluid mass directly to upward buoyant force and cargo-carrying capacity.

• Integrates Applied Math & Ratio Calculations: Teaches students how to measure vessel dimensions and compute mass efficiency ratios.

• Low-Cost High-Engagement STEM: Uses inexpensive household items like aluminum foil, craft sticks, tape, and pennies for an engaging Thanksgiving science challenge across Grades 6–8.
