Involving students in authentic science work is one way to enhance their interest in science. This paper reports a project in which Year 4-7 students actively participated in a study that involved the provision of a suitable nesting site for local turtles. The students collected data on turtle nests at the site and evidence of turtle hatchlings at it and in the wider wetlands locality. Thirty-one turtle nests were located at the site during the project but all were predated. Teaching and learning outcomes are discussed. (Contains 3 figures.)
