LO 2

Technological Knowlede 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 how materials can be processed to change or improve properties (e.g. strength, fire resistance, waterproofing, taste, volume, texture).

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 suggests ways to improve technological products or processes to minimise negative effects on people and/or the health of the environment.
