Celebrate National Science Week 2026 (15–23 August) with free curriculum-aligned resources for early learning, primary and secondary students. This year’s theme—Seeds of Science: Nurturing science for all.—invites students across Australia to explore the power of curiosity, inquiry and shared learning in growing scientific understanding.


This theme invites students across Australia to explore the power of curiosity, inquiry and shared learning in growing scientific understanding. Just as seeds need the right conditions to grow, knowledge flourishes when it is nurtured, shared and applied to real-world and authentic challenges across all the scientific disciplines.
The theme encourages schools to explore how ideas take root, develop and spread – from the first spark of a question to the sharing of discoveries that benefit the wider community. It’s a celebration of how knowledge grows when tended with care, creativity and collaboration.
