Lesson notes

Learning Objectives

Indicator: B7.4.1.1.1 - Outline the uses of structures in construction

By the end of the lesson, learners can:

Define a structure in construction in their own words, with at least one example of how structures support or carry loads to prevent collapse.
Classify given structures as natural or man-made, and as frame or shell, giving a reason for each classification.
Outline at least three uses of structures in construction, including carrying loads and supporting parts of artefacts.
Sketch and label simple frame and shell structures with acceptable accuracy.
Contribute sketches to a class sketch album and explain their sketches clearly to peers.

Exemplars (from the NaCCA curriculum)

1. Explain what is meant by structures in construction.
E.g., Method of supporting loads (triangulation, truss) to prevent collapse.
2. Identify and classify structures under natural and man-made
E.g.
- Natural: structures created by nature to provide support (spider web, honeycomb and human skeleton)
- Man-made: structures made by man to provide protection and support, (chairs, helmets, suspension bridge)
3. Classify structures under frame and shell.
E.g.
- Frame structures: crane, electricity pylon and building
- Shell structures: body of motor car shaped from panels.
4. Discuss the uses of structures in construction.
E.g.
- Carrying loads for which they were designed without toppling over or collapsing
- Supporting the various parts of artefacts
5. Make sketches of both frame and shell structures and prepare a sketch album to use as materials for learning structures.
6. Display the sketch album for appraisal
