# Solar panels: Modelling and data analysis – Lesson 1

## Learning Objectives

- Know how to take measurements from scale drawings.
- Solve a problem using measurements from a scale drawing.
- Calculate areas of complex shapes.
- Analyse your solution to understand its effects.

## Lesson Description

This maths topic uses the real-life context of the British America’s Cup team INEOS TEAM UK. Students will explore the modelling and data analysis behind INEOS TEAM UK’s team’s solar panel array during the 35th America’s Cup. Over two lessons, they will use the blueprint of the base’s roof to design the array, calculate area and analyse real data to evaluate the energy produced.

Use the film to discuss the motivations behind the team’s decision to install solar panels, the impact it has and the ways they monitor its efficiency and effectiveness.

The class-facing presentations provide clear lessons with differentiated worksheets to reinforce the curriculum-linked learning objectives.

This resource can be used either in sequence or flexibly as an introduction to a topic, or for a quick activity.
