Lesson Structure

When students go through this lesson in each section the objectives they will learn are:

• Warm-up – Recognize the importance of automation in the development of technologies that enable humans to work faster, safer, and more efficiently. 
• Imagine – Explain how cranes have utilized the mechanical advantage of levers throughout history and in the modern world to build and construct, as well as the human role in operating cranes.
• Create – Create a 2D crane for exploring levers with linkages for mechanical advantage. 
• Build – Build a controlled system using levers to move the crane to lift and drop.
• Reflect – Reflect on the role that crane automation could play in improving the industry, Innovation, and Infrastructure as well as health and wellbeing.
• Challenges – Extend your learning through real-world design challenges.

After this lesson students will be able to:

• Recognize several ways that automation helps humans complete difficult or repetitive tasks. 
• Design a mechanical structure using levers pushed and pulled by the mechanical linkage connected to the servo motor. 
• Refine the crane's design through creating tests such as objects to pick up, exchanging different kinds of linkages, straw sizes, repositioning the motor, or changing the code.
• Demonstrate the transfer of energy from place to place through the electric servo motor.
• Understand innovation of an invention through history and realizing the future of automation and how it contributes to improving human work conditions.
