Nayland College students become marine biosecurity detectives at interactive Cawthron-led workshop

The workshop, developed by Nayland science teacher Gerd Banke in collaboration with the Cawthron-led Marine Biosecurity Toolbox project, explored biosecurity, biodiversity, molecular tools and environmental DNA (eDNA) to detect invasive species — all interwoven with Mātauranga Māori perspectives.

This year 280 Year 9 students participated in the workshop on 15 September. The day involved examining biofouling plates using microscopes, magnifying glasses and touch to determine the species living on them. They also got to learn about amazing new technologies available to detect what is lurking in the water, such as collecting eDNA.

Cawthron Biosecurity Team Leader Xavier Pochon and his team of 6 other Cawthron scientists have led the sessions every year with enthusiasm. “We love to see student’s faces light up when they understand a new scientific concept,” says Xavier.

Some feedback received from students this year included:

• It was cool to see what is living under the water at our marina.
• We got to do things we don’t normally do in science.
• I thought it was interesting and interactive.
• It was fun and I learned new things about sea life and pests.

Inspiring young people to explore science is an important part of Cawthron’s annual outreach programme. By working with students, our scientists can share their passion for the environment and show how science helps protect the places we all care about. These hands-on experiences spark curiosity, build confidence, and encourage the next generation to see themselves as future scientists and problem solvers.
