Bionic Robotic Hand Tendon Mechanics STEM Lab (BIO01)

Bring human body systems, musculoskeletal interactions, tendon mechanics, and biomimicry to life with the Bionic Robotic Hand Tendon Mechanics STEM Lab (BIO01)! Designed for Middle School Life Science, Biology, Anatomy, Math, and STEM classes, this 3-page, print-ready lab packet challenges students to construct an articulated 5-digit prosthetic hand driven by string flexor tendons.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-LS1-2 Cell & Body Systems Organisms, MS-LS1-3 Body System Subsystems Interaction, MS-ETS1-2 Engineering Design), key anatomical mechanics concepts, straw joint template setup directions, expected learning outcomes, and a full teacher answer key.

• 🦾 Page 2: Student Mission Card & Blueprint

  Hooks students with a real-world biomedical engineering mission to construct functional prosthetic limbs. Includes material constraints (cardstock, straws, yarn/string, metric ruler, tape, scissors, testing items) and a dedicated schematic sketching zone to diagram phalange hinge joints, tendon guide sheaths, and pulling force vectors.

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured lab testing table tracking target payload objects, grip hold time in seconds, pulling force in grams or Newtons, and articulation notes. Includes an applied math section to calculate Grip Efficiency Ratios (Payload Mass / Tendon Force), followed by reflection questions analyzing skeletal-muscular coordination, friction, and joint leverage.

Educational Value & Key Benefits:

• Hands-On Human Anatomy Physics: Connects muscular contraction and tendon tension directly to physical mechanical advantage and movement.

• Integrates Applied Math & Efficiency Ratios: Teaches students how to calculate mechanical force ratios using mass balance measurements.

• Low-Cost High-Engagement Life Science STEM: Uses budget-friendly items like cardstock, straws, string, and tape for an unforgettable biomedical lab across Grades 6–8.
