Rapidly developing molecular technologies provide new opportunities for upgrading secondary school science programmes. They allow bringing hands-on eDNA experience into the classrooms, while building students’ understanding of the environment and expanding their awareness of current global issues regarding protection of our natural resources. Here I present the development of a 6-week educational unit aligned with the New Zealand Science Curriculum. It is aimed at developing students’ understanding of fresh water and marine ecology, pests, pest management, biosecurity, classification, DNA, and the application of eDNA as a role in marine pest detection. The purpose is to empower young people to see themselves as kaitiaki of their local coastline as they develop the awareness, knowledge and skills to become active participants in future marine pest detection using eDNA. Cawthron scientists and eDNA kit providers are eager to support schools and their students with hands-on practical experience, including DNA extraction and DNA sequencing. This outreach programme aims to bridge the knowledge gap and provide schools with ready-to-go activities that are aligned with the New Zealand secondary science curriculum. The activities provide a wraparound approach, ensuring that when Cawthron scientists visit New Zealand schools, the students will have sufficient knowledge and understanding of eDNA and New Zealand marine ecology to engage in the experience of using eDNA as a citizen science tool for marine pest detection.
