The study was designed to compare the behavior of members and non-members of school conservation club in the area of knowledge of environmental conservation, attitude to environmental conservation and involvement in environmental conservation. The impact of school type, gender and stream on environmental conservation behaviour of students were also investigated. A sample of 575 secondary school students consisting of 275 of the school conservation club members and 300 non-members, was drawn from six randomly selected private and public secondary schools with functional conservation clubs in Ojo Local Government Area of Lagos State. Data analysis shows that there is a significant effect of club membership, stream of class and school type on students’ knowledge, attitude and involvement in environmental conservation. Members of school conservation club performed significantly better than non-members on all the three aspects of environmental conservation behaviour investigated. It was also observed that gender does not significantly affect students’ knowledge, attitude and involvement in environmental conservation. Since establishment of a functional school conservation club has been linked to positive environmental conservation behaviour, all schools should be encouraged to have it. Other States should take a cue from Lagos State as this is a significant way of promoting learning outside the classroom.enSchool Conservation ClubEnvironmental ConservationStudents' BehaviourArticle
