Lesson Keywords

Career – A chosen profession or occupation.
Machinist – A skilled worker who operates machine tools to produce precision parts.
Fitter – A skilled worker who assembles and installs mechanical parts and equipment.
Fabricator – A skilled worker who cuts, shapes, and joins metal to create structures or products.
Welder – A skilled worker who joins metal pieces together using heat.

Differentiation

For pupils who grasp concepts quickly, they can be asked to research other lesser-known metal work careers. For those needing more support, the teacher will provide simplified definitions and more visual aids, allowing them to focus on identifying roles rather than listing all functions.

Note for teachers using this lesson plan

Teachers should ensure to use real-life examples and practical scenarios to make the lesson more relatable and engaging for the pupils. Encourage questions and discussions to deepen understanding and address any misconceptions. Safety aspects related to each career should also be briefly touched upon.
