- Night-lights as technological systems
Discussion starters
- Technological systems: Use this and other examples to identify the components of a technological system and how they are connected. Identify the input/s and output/s of particular technological systems and that a system transforms an input to an output. (level 1)
- Technological systems: Use this and other examples to describe the change that has occurred to the input to produce the output in simple technological systems and identify the role each component has in allowing the inputs to be transformed into outputs within simple technological systems. (level 2)
- Characteristics of technological outcomes: Describe what technological outcomes are and explain how they are different to natural objects and other things created by people. (level 2)
