YES Competition 2025-26 – The Results

This year’s Young Environmental Scientists competition encouraged students across the Caribbean to think creatively and sustainably developing solutions to help the protection of the species and environment in their area. We have received a number of submissions, showcasing the creativity and scientific thinking of students of Caribbean students.

We at Macmillan Education Caribbean are proud to present the winners of the YES Competition 2025-26:

1^st Place – Eco-Hero Team, Tunapuna Presbyterian Primary School, Trinidad & Tobago

After discovering a large number of single-use plastic spoons were being thrown away at their school and sent to landfill, these Eco-Heroes started a campaign to encourage the collection and reuse of plastic lunch utensils such as spoons and forks. They also invited students to get involved with a poster competition. After 2 weeks, the group managed to save 15 plastic spoons from landfill.

2^nd Place – SVG Wildlife Warriors, Calliaqua Anglican Primary School, St Vincent & The Grenadines

The Wildlife Warriors decided to focus on four endangered species on their island, their causes of engagement and ways that they could support each species. Using their research, they developed a board game to teach players about wildlife conservation while having fun in the process.
