Questions often heard echoing through classrooms are: 'Why do I need to know this?' and 'When will I use this in real life?'. Working with the Centre for Industry Education Collaboration (CIEC), the authors chose a curriculum segment that aligned with some of their own research -- microorganisms: how they can harm us, help us and how we can use them to our own advantage. The aim was to put this concept into a real-life context for the students to understand the application outside the classroom. The authors introduced the concepts of biotechnology and the development of new medicines, all within the classroom, whilst demonstrating the inclusivity and accessibility of science. The aim of this session was to encourage the children to see science as interesting and accessible. The intention was to provide an insightful and memorable experience for all, showing the importance of the scientific topics and how these can be utilised in a research laboratory.
