Lesson summary
Students will solve practical problems by calculating the volume of cylinders and applying rates and ratios to optimise the energy capacity of the Kidston pumped hydro renewable energy project. They will use mathematical modelling to evaluate real-world engineering challenges in renewable energy.
Learning intentions:
Students will...
- explore the role of civil engineering in renewable energy projects such as the Kidston Pumped Hydro project
- investigate how mathematical concepts such as volume, rates, and ratios can be applied to solve real-world engineering challenges.
Success criteria:
Students can...
- calculate quantities that are directly proportional to another
- calculate the volume of a cylinder
- apply mathematical reasoning to a real-world context and present a mathematical justification for how increasing water usage in the Kidston pumped hydro project can improve energy output, using real-world data from the project.

Curriculum Mapping
Australian Curriculum (v9.0) content description: Year 9 Mathematics
Students learn to:
- solve problems involving the volume and surface area of right prisms and cylinders using appropriate units (AC9M9M01)
- use mathematical modelling to solve practical problems involving direct proportion, rates, ratio and scale, including financial contexts; formulate the problems and interpret solutions in terms of the situation; evaluate the model and report methods and findings (AC9M9M05).
Relevant parts of Year 9 achievement standards: Students apply formulas to solve problems involving the surface area and volume of right prisms and cylinders. They use mathematical modelling to solve practical problems involving direct proportion, ratio and scale, evaluating the model and communicating their methods and findings.
NSW Syllabus outcomes:
- applies knowledge of volume and capacity to solve problems involving right prisms and cylinders (MA4-VOL-C-01)
- solves problems involving ratios and rates, and analyses distance–time graphs (MA4-RAT-C-01)
General capabilities: Critical and Creative Thinking, Numeracy
Cross-curriculum priority: Sustainability
Level of teacher scaffolding: Medium: facilitate class discussion.
