Science Week 2025 at St Leo's was a celebration of curiosity and creativity, inviting students to explore the mysteries of the universe through hands-on activities, inspiring talks, and imaginative displays.![]()
From Year 9 Forensics and Year 10 Depth Studies to fun fancy dress and hearing about fascinating career options, Science Week reminded students that science is everywhere, from the tiniest atom to the vastness of space. ![]()
Well done to Mr Gould and all the Science team. The week certainly sparked a deeper love of discovery and a sense of wonder about nature and science.
