More than just science

I often begin my 'Everyday Science' and 'Natural Science' lectures – now compulsory for students from Arts, Social Sciences, Islamic Learning, Management and Administrative Sciences, Linguistics, etc – with a simple yet profound question: What does it mean to think scientifically if you do not belong to the Faculty of Science? For many of these students, this question becomes the first step in a journey that quietly shifts the way they see the world.

In my experience as both a teacher and a learner, scientific literacy is not a fixed achievement but an evolving orientation. It is less about possessing a storehouse of facts and more about cultivating a way of looking at the world that values evidence, inquiry and intellectual humility. Scientific literacy is a style of thinking that can illuminate all walks of life.

Teaching science to students from non-science faculties is both a challenge and a privilege. It forces me to return again and again to the foundations of knowledge. I find myself stripping away jargon, decoding complex theories and anticipating the misconceptions that students may carry. In doing so, I am reminded that to teach science well, one must first learn to think clearly and speak simply. Scientific literacy, in this sense, becomes a shared project between teacher and student: we are learning, together, how to ask better questions.

Traditionally, scientific literacy has been equated with a basic grasp of scientific facts and laws: knowing that water is composed of hydrogen and oxygen, that the Earth orbits the Sun, or that vaccines protect against disease. This foundational knowledge is important. It helps individuals participate meaningfully in conversations about public health, environmental crises and technological change. But in an age where information is abundant and half-truths travel as fast as facts, this narrow definition is no longer enough.

True scientific literacy requires a deeper understanding of how science works as a process. It means knowing how hypotheses are formed, how experiments are designed, how data are analysed, and how conclusions are drawn, and then revised when new evidence emerges. It involves recognising that science is not a catalogue of certainties but a disciplined search for patterns, probabilities and better approximations of truth.

This also includes an appreciation of methodological rigour: why sample size matters, why control variables are important, and why transparency in reporting research is crucial. A scientifically literate person, when confronted with a headline about a 'new study', is able to ask: Was this study peer-reviewed? Was the sample size adequate? Could there be bias in the method or interpretation? Such questions are essential tools for responsible citizenship in a world increasingly governed by data and expert claims.

For me, scientific literacy also carries an epistemological dimension: an awareness of the nature and limits of knowledge itself. It encourages students to ask: How do we know what we claim to know? What counts as reliable evidence? When should we doubt, and when should we trust? This kind of reflection nurtures a healthy skepticism that resists both gullibility and rigid dogmatism.

Scientific literacy reaches far beyond science classrooms. It shapes how we read statistics in the news, assess medical claims on social media, and judge policies on climate, health and technology. It strengthens everyday decisions from choosing a treatment to interpreting a survey or debating social issues with friends. Across disciplines, scientific thinking deepens students' work: a literature student evaluates interpretations, a business student weighs risk and trends, an economics student interprets data and policy, and a criminology student examines patterns and evidence. In each case, core habits of mind – i.e. critical inquiry, evidence-based reasoning and openness to revision – are essential. The purpose of teaching 'Everyday Science' or 'Natural Science' to students outside the Faculty of Science is therefore not to turn them into physicists, biologists or chemists, but to help them become informed, reflective citizens who can navigate an increasingly complex world with greater clarity, curiosity, responsibility and care.
