Lesson summary
Students will explore how science can be used to reduce water usage in plastic production processes. They will compare water usage in virgin and recycled plastic production before creating a flow chart to show where water usage could be reduced in either one of these processes.
Learning intentions:
Students will...
- compare the water used in the production of a new single-use plastic bottle to a recycled plastic bottle.
Success criteria:
Students can...
- explain how science can be used to develop new methods of plastic production that minimise water usage
- create flow charts for new and recycled plastic production processes.

Curriculum Mapping
Australian Curriculum (v9.0) content description: 7 & 8, Science
- Students learn to explain how new evidence or different perspectives can lead to changes in scientific knowledge (AC9S7H01/AC9S8H01)
- Students learn to examine how proposed scientific responses to contemporary issues may impact on society and explore ethical, environmental, social and economic considerations (AC9S7H03/(AC9S8H03).
Relevant parts of Year 7 achievement standards: Students identify the factors that can influence the development of and lead to changes in scientific knowledge. They explain how scientific responses are developed and can impact society.
Relevant parts of Year 8 achievement standards: Students analyse how different factors influence the development of and lead to changes in scientific knowledge. They analyse the key considerations that inform scientific responses and how these responses impact society.
NSW Syllabus outcomes:
A student presents science ideas, findings and information to a given audience using appropriate scientific language, text types and representations (SC4-9WS)
General capabilities: Critical and Creative Thinking
Cross-curriculum priority: Sustainability
Level of teacher scaffolding: Medium - facilitate class discussion and mind-map making, support students in creating flow charts.
