Welcome to the Cawthron Scitec Expo.

This event encourages and supports Nelson Tasman students to pursue STEAMs – science, technology, engineering, arts and maths.

Our founder, Thomas Cawthron, believed science was the key to a better future. This event sees local schools, organisations and businesses collaborating to inspire the next generation of scientists in Te Tau Ihu.

Scitec Expo

Every second year we run a full expo for Years 1-13. This is where students are invited to submit science, research, technology or art projects. These are publically displayed and reviewed by a team of expert assessors who interview students as part of the assessment process. All primary, intermediate and secondary students from Nelson-Tasman are eligible to enter. The next full expo will be in 2025.

This year we are introducing an exciting new event to encourage and support STEAMs education. Stay tuned to this webpage or sign up to our newsletter to learn more.

Thank you!

Our 2023 Expo saw 273 science experiment, research, technology and art exhibits created by just over 600 students from 19 schools on display at Founder’s Heritage Park in Nelson on 22-23 August. These projects were assessed by 56 volunteer judges.
