Sustainable lighting design

Design and make a sustainably powered light

This fun engineering project for KS3 will allow students to embrace sustainable engineering as they learn to combine scientific principles with artistic flair to craft their unique and planet-friendly light.

This activity could be used as a main lesson to teach about the benefits of using renewable energy and how it can help solve social problems. It could also be used as part of a wider scheme of learning focussing on sustainability and the 6Rs (rethink, refuse, reduce, reuse, recycle, repair).

Approximately 1 billion people worldwide, or 15% of the total population, have no access to mains electricity. How could a lamp be powered for children living in these conditions to enable them to read and study at night?

What you will need
Hi-bright light emitting diodes (LEDs).
Block connectors with two pin connections at either end, or solder and soldering equipment.
Insulation tape.
Red and black wires or crocodile clips.
A low power DC generator/motor (a motor working in reverse acts as a generator).
Pre-made or purchased turbine blades to attach to the generator.

The engineering context
Engineers bear a social and ethical obligation to consider the environmental impact when addressing design challenges. Understanding how to generate greener energy is imperative for aspiring electrical or electronic engineers, given that the renewable energy sector is one of the rapidly expanding industries in the field of engineering.

Suggested learning outcomes
By the end of this activity, students will be able to understand what is meant by, and the need for, renewable energy. They will be able to design and make a sustainably powered light, and they will understand how wind turbines work.
