Leonardo invented many things, but one thing that Leonardo was revolutionary at was his ability to make cogs, gears and bearings. Cogs, gears and bearings had been around before Leonardo, but he made them better.

In this lesson, students are to assemble different cogs, gears and bearings systems of Leonardo Da Vinci. This is an opportunity to experiement and explore the different oblects that Leonardo created, and are now taken for granted, but make our life easier.

This is an exploration lesson, and an appreciation for the cogs, gears and bearings of Leonardo is the aim, and leads directly to the next lesson which explores another man who is into making interesting contraptions.

Once completed students are to post there cog or gearing system onto this page as a video.

Signs of Success:
  1. To have assembled an cog or gearing system of Leonardo Da Vinci.
  2. Post a Video of the cog or gearing system on this page.

A number of the resources on the Resources page will be very useful for this task.

This leads us to the next lesson, "Doing Da Vinci and Blair Somerville Footage".

Technological practice
Students will:
Planning for practice
  • Undertake planning to identify the key stages and resources required to develop an outcome. Revisit planning to include reviews of progress and identify implications for subsequent decision making.

Brief development

  • Describe the nature of an intended outcome, explaining how it addresses the need or opportunity. Describe the key attributes that enable development and evaluation of an outcome.

Outcome development and evaluation

  • Investigate a context to develop ideas for potential outcomes. Trial and evaluate these against key attributes to select and develop an outcome to address the need or opportunity. Evaluate this outcome against the key attributes and how it addresses the need or opportunity.
Technological knowledge
Students will:
Technological modelling
  • Understand that different forms of functional modelling are used to inform decision making in the development of technological possibilities and that prototypes can be used to evaluate the fitness of technological outcomes for further development.

Technological products

  • Understand the relationship between the materials used and their performance properties in technological products.
Nature of technology
Students will:
Characteristics of technological outcomes
  • Understand that technological outcomes are recognisable as fit for purpose by the relationship between their physical and functional natures.
