As a school we celebrated British Science Week. We decided to have an Eco focus and to link the work to our Project Based Learning on the problems of plastic pollution and the environment.  In some classes the children studied about decomposition through investigations.  In other classes the children the generated their own learning focus and planned their own investigations. This led to discussions about sponsoring an endangered animal.  A group of children were tasked with performing short presentations to the school on endangered animals. The children then had a chance to vote for the animal most in need of support with the aim of raising sponsorship through a School Council Event.
