The Wild Citizens! project encourages and supports primary school children to become active citizen scientists and environmental citizens by focusing on wildlife in their school grounds. As future stewards of the planet, it is vital that today’s children understand about climate change and sustainable development, and know how to engage in activities which help protect the environment. The pupils participate in designing and constructing an outdoor ‘Wild Science Lab’ to attract, protect and record wildlife. They develop data-handling skills and communicate their findings within their local community, whilst reaping the health and wellbeing benefits of connecting with nature. Additional components to the project are CPD training in outdoor education for primary school teachers, and creating an environmental education network for Southampton primary schools.
