Learning Objectives

Indicator: 2.4.2.LI.4 - Apply an appropriate finish to an artefact

By the end of the lesson, learners can:

Select and justify the most appropriate finish for a given woodwork artefact based on its intended use, appearance, and durability requirements.
Demonstrate the correct sequence of surface preparation processes (planing, scraping, glass papering, and filing) on a woodwork artefact.
Apply at least one finish (lacquer, varnish, paint, or polish) to a model or artefact using the correct tools and techniques.
Evaluate the quality of their finished work against given criteria, including smoothness, evenness of coating, and cleanliness.
Apply safety measures and demonstrate work ethics (cleanliness, patience, self-control, and responsibility) when handling finishing materials.

Critical Thinking and Talk for Learning Approaches: Learners think pair share to passionately identify and describe the tools and materials for preparation of surfaces of artefacts (cleaning-up).
Group work/Collaborative Learning:
- Organise learners into mixed ability to co-operatively and passionately identify the different types of finishes for an artefact with open-mindedness.
- Guide learners in mixed gender groups to discuss the uses of the following finishes co-operatively and passionately:
1. Lacquers
2. Vanishes
3. Paints
4. Laminated Plastics
5. Polishes E xperiential learning/ Group work/Collaborative Learnin g:
- Assist learners to courageously and passionately demonstrate processes such as: planning, scraping, glass papering, filing, staining, bleaching, spraying and polishing taking into consideration work ethics and self-control.
- Task learners in mixed ability groups to select an appropriate finish for artefact co-operatively and passionately
- Engage learners in mixed gender ability groups to apply the right type of finishes to artefacts/models taking into consideration work ethics.
- Task learners with open-mindedness to apply safety measures when finishing, taking into consideration work ethics.
