Title: Sustainable Robotic Arm: Exploring Tendons and Muscles

Level: Intermediate to Advanced

Objective: - Activate prior knowledge about tendons and muscles - Brainstorm ideas for creating a robotic arm using sustainable materials - Develop teamwork, critical thinking, and problem-solving skills - Promote environmental awareness and sustainability

Materials: - Whiteboard or flipchart - Markers - Pictures or diagrams of tendons and muscles - Sustainable materials (e.g., recycled cardboard, paper, straws, rubber bands, etc.) - Scissors, glue, tape - Optional: Laptops or tablets for research

Duration: 90 minutes

Procedure:

1. Warm-up (10 minutes):
   • Begin the lesson by asking students what they know about tendons and muscles.
   • Write their responses on the board and discuss the functions and importance of tendons and muscles in the human body.
   • Show pictures or diagrams of tendons and muscles to reinforce understanding.
2. Brainstorming Activity (20 minutes):
   • Divide students into small groups and provide each group with a large sheet of paper and markers.
   • Instruct students to brainstorm ideas for creating a robotic arm using sustainable materials.
   • Encourage them to think creatively and consider the functions and structure of tendons and muscles.
   • Each group should write down their ideas and draw a rough sketch of their robotic arm design.
3. Group Discussion (15 minutes):
   • Have each group present their ideas and designs to the class.
   • Encourage other groups to ask questions and provide feedback on the presented designs.
   • Discuss the importance of sustainability and how their designs incorporate sustainable materials.
4. Robotic Arm Construction (40 minutes):
   • Provide students with the necessary materials for constructing their robotic arms.
   • Instruct them to work in their groups and follow their design plans.
   • Circulate the classroom, offering guidance and support as needed.
   • Encourage students to experiment, modify, and improve their designs during the construction process.
5. Wrap-up and Reflection (5 minutes):
   • Once the construction time is over, ask each group to briefly explain their final robotic arm design.
   • Discuss the challenges they faced during the construction process and how they overcame them.
   • Emphasize the importance of sustainable materials and how their robotic arms contribute to a greener future.

Extension Activity (optional): - Ask students to research and present examples of real-life robotic arms that are made from sustainable materials. - Encourage them to explore how these robotic arms are used in various industries and their impact on the environment.

Note: Depending on the available time and resources, the construction phase can be extended to multiple sessions, allowing students to refine their designs and test the functionality of their robotic arms.
