As the number of smartphone users worldwide exceeds 2 billion, and as users update their devices with ever-increasing frequency, there are growing concerns about the impacts of smartphone manufacture and disposal on the environment and human health. In this activity, students use knowledge about Earth resources, as well as applying their working scientifically skills, to work out how to persuade phone manufacturers to make eco-friendly smart phones from sustainable materials.


Eco-phone is a way to make project-based learning easy, and get students more confident with real-life science issues. A Project simulates how students will meet issues in everyday life and provides less support than other ENGAGE activities.

The Project begins by engaging students with the dilemma. It sets up the ‘research questions’ for students to answer and provides a range of ‘sources’ containing the information they need. Students come to an informed opinion and communicate their views.

A project can be done in 2 lessons, or over a longer time. It makes an ideal opportunity to work with experts, such as ‘science ambassadors’, to learn about science in society. This video describes how a Project works

Student-led with a teacher intro.
Students plan how to communicate their findings to a group of smartphone manufacturers.


Grass-resin casing

Video and web article An engineer talks about how his company build smartphone casings out of grass.

Research paper An investigation into the properties of a resin/grass composite. Students can read the abstract (the full paper is not in the public domain). An adapted version is also available.

Tree fibre circuit board

Research paper This article is available if students wish to see the original although the language is difficult. We have supplied an adapted version.

Press release about tree fibre circuit boards.

Sugar battery

Research paper This contains lots of technical language, which students will not be familiar with. We have created an adapted version with simpler language.

Web article A more accessible text that outlines useful information about sugar batteries.

Video Scientists developing sugar batteries discuss how they work and the advantages of them over conventional lithium batteries
