|
Achievement Objective
Students will:
- Understand that technological products are made from materials that have performance properties.
|
Achievement Objective
Students will:
- Understand that technological systems have inputs, controlled transformations, and outputs.

Teacher Guidance
To support students to develop understanding of technological modelling at level 1, teachers could:
- provide students with the opportunity to discuss why technological modelling is important to the development of technological outcomes and that it involves both functional modelling and prototyping.
- guide students to identify that functional models are representations of potential technological outcomes and that they exist in many forms (e.g. thinking, talking, drawing, physical mock-ups, computer aided simulations etc)
- provide students with the opportunity to discuss that design concepts includes design ideas for parts of an outcome, as well as the conceptual design for the outcome as a whole
- provide students with the opportunity to interact with a variety of functional models and guide them to identify that the purpose of functional modelling is to test design concepts to see if they are suitable for use in the development of an outcome
- guide students to identify that prototypes are the first versions of fully completed technological outcomes
- provide students with a range of prototyping examples and guide them to identify that the purpose of prototyping is to test the outcome. Examples should include the modelling practices of technologists.

Teacher Guidance
To support students to develop understanding of technological products at level 1, teachers could:
- provide students with a range of technological products and encourage them to explore these through such things as: using, 'playing', dismantling and rebuilding as appropriate;
- guide students to identify the materials that the products explored are made from;
- provide opportunity for students to discuss that performance properties of materials refer to such things as thermal and electrical conductivity, water resistance, texture, flexibility, colour etc;
- provide students with the opportunity to explore common materials and guide them to identify their performance properties;
- provide students with a range of technological products to explore and guide them to identify ways in which materials have been manipulated to make the product. For example, in a wooden toy the wood has been shaped, sanded and painted; In a sandwich, the bread dough has been shaped, cooked and sliced; in a cushion the fabric has been cut and sewn together.

Teacher Guidance
To support students to develop understanding of technological systems at level 1, teachers could:
- provide students with a range of technological systems and encourage them to explore these through such things as: using, 'playing', dismantling and rebuilding as appropriate;
- guide students to identify the components and how they are connected in the systems explored;
- guide students to identify the inputs and outputs of technological systems and provide opportunity for them to recognise that a controlled transformation has occurred.
