Science in action with P4/5.

12th May 2026

Today, the children used recycled bottles to carry out an exciting science experiment exploring the different layers of the ocean. By carefully following a set of instructions, they created their own visual “ocean in a bottle,” helping them to understand how liquid density forms distinct ocean zones.

It was a fantastic hands-on learning experience, allowing the children to combine creativity with science while deepening their understanding of the natural world.
