Fair Play & Fair Trade

Chain Reaction : fair play in Chemistry

14 September 2026

It started with a question that felt, frankly, like a bit of a stretch:

Could Bala ever belong in a chemistry lesson?

We’re developing educational resources, and while sports balls can take you naturally into geography, economics, citizenship, sustainability and PE... Chemistry? Really? Then we began thinking about what chemistry actually describes.

Exchange. Transfer. Energy. Relationships.

Atoms have no morals and molecules don’t negotiate. But chemistry does something rather useful: it forces us to account for both sides of an exchange.

And perhaps that is exactly where a lesson about Fair Trade begins.

1. Every exchange has another side

Take a redox reaction.

In a simple electron-transfer redox reaction, oxidation cannot happen without reduction somewhere else. You cannot properly describe the overall reaction by looking at only one half of the exchange.

Like a trade, there are always two sides.

We see a football and a price. But a bargain doesn’t appear from nowhere. If something becomes dramatically cheaper at one end of a supply chain, chemistry gives us a useful instinct:

what happened at the other end?

Who gave what? Who received what? Where did the cost go?

Fair trade begins by refusing to tell only one side of the story.

2. A good exchange can enable more than it transfers

Chemistry gets even more interesting when reactions are coupled.

An energy-releasing reaction can power another process that couldn’t otherwise happen. The energy isn’t simply lost. It is captured and turned into movement, growth, repair or something new.

One transformation makes another possible.

That feels remarkably close to what a good trade can do. A worker’s skill creates a ball. The ball creates a game. The game creates exercise, friendship, joy and belonging. Payment creates income. Income creates choices. Money moves into families, shops and communities.

A good exchange releases possibility.

That, perhaps, is the deeper purpose of fair trade: not simply to transfer money more fairly, but to keep the exchange generative at both ends.

3. Chemistry asks where everything went

Chemistry is unforgiving about disappearing costs. Matter has to be accounted for. Charge has to balance. Energy goes somewhere, even when it isn’t where we hoped it would be. That is a useful habit to take into economics.

An apparently efficient system can still push its costs somewhere else: into someone’s time, insecurity, exhaustion or lack of choice.

The ball may be identical. It still rolls. It still bounces. But if our enjoyment depends upon diminishing someone else’s security, choices or quality of life, something in the exchange has gone wrong.

The process is creating possibility here by removing it there.

And that brings us back to play.

Someone’s work becomes someone else’s play.

It is one of the remarkable things human beings do: our effort can enrich the lives of people we may never meet. But surely the exchange is at its best when the person who creates our play has room for a full life of their own.

We probably can’t claim that fair exchange is the law that powers the universe. But perhaps chemistry offers something more useful than that.

The universe we study through chemistry is built on relationships, interactions and transfers. Change does not happen in isolation. To understand an exchange, you have to look at the whole system — not merely the part that benefits you.

Which, come to think of it, sounds rather like a game.

Players buzz around an inflated nucleus, constantly exchanging possession, space, effort and opportunity. A pass only has meaning because someone gives it and someone receives it. One movement creates space for another. One player’s run makes another player’s chance possible.
