Lesson Objectives

Objective:
Students will design and construct a functional mechanical hand using simple materials, exploring engineering concepts such as mechanical systems, biomimicry, and the design process.

Learning Goals:

1. Understand the basic anatomy of a human hand and its movements.

2. Apply the engineering design process to create a functional prototype.

3. Explore design constraints and problem-solving strategies.

Design Constraints:

1. • 1. The hand must have at least three moving fingers.

     2. Fingers should be able to bend and return to their original position.

     3. Must be constructed entirely from the provided materials.

Materials:

• 1. • Cardboard (sturdy but easy to cut)

     • String or thread

     • Drinking straws (plastic or paper)

     • Glue (hot glue preferred for quick setting, with supervision)

     • Scissors or craft knives (with teacher oversight)

     • Markers or pens

     • Rulers

     • Tape

     • Paper for sketching

Wrap-Up and Reflection (10 minutes)

• Discuss:

  • What worked well in your design?

  • What challenges did you face, and how did you solve them?

  • How might this project relate to real-world prosthetics or robotics?

• Extension: Encourage students to brainstorm additional features, like a thumb or grip mechanisms.

Assessment:

• Participation: Active involvement in the design and building process.

• Functionality: The mechanical hand should demonstrate basic finger movement.

• Reflection: Students explain their design choices and reflect on the challenges and successes.
