Introduction to structures

Assessment

LO 1

TECHNOLOGICAL PROCESSES AND SKILLS

The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technologies.

We know this when the learner:

Investigates:

1.2 finds out about existing products relevant to a problem, need or opportunity, and identifies some design aspects (e.g. who it is for, what it looks like, what it is for, what it is made of);

1.3 performs, where appropriate, scientific investigations about concepts relevant to a problem, need or opportunity using science process skills;

Designs:

• writes or communicates, with assistance, a short and clear statement (design brief) related to a given problem, need or opportunity that demonstrates some understanding of the technological purposes of the solution;

Makes:

1.7 outlines a plan that shows the steps for making, including drawings or sketches of main parts;

1.8 uses suitable tools and materials to make products by measuring out, cutting or separating, shaping or forming, joining or combining, and finishing the chosen material;

Evaluates:

1.11 evaluates the plan of action followed and suggests improvements and modifications if necessary;

Communicates:

1.12 produces labelled two-dimensional drawings enhanced with colour where appropriate.

1.13 uses appropriate technologies to produce presentations that record and communicate the design process (e.g. simple portfolio, posters, charts, models).

LO 2

TECHNOLOGICAL KNOWLEDGE AND UNDERSTANDING

The learner will be able to understand and apply relevant technological knowledge ethically and responsibly.

We know this when the learner:

Structures:

• demonstrates knowledge and understanding of different types of structures (e.g. frame, shell, solid), and of the relationship between materials and the load a structure of a product can support.

LO 3

TECHNOLOGY, SOCIETY AND THE ENVIRONMENT

The learner will be able to demonstrate an understanding of the interrelationships between science, technology, society and the environment.

We know this when the learner:

Indigenous Technology and Culture:

3.1 recognises how products and technologies have been adapted from other times and cultures;

Impact of technology:

3.2 identifies possible positive and negative effects of scientific developments or technological products on the quality of people’s lives and/or the health of the environment.
