This small book has been written to share the results of a research study on concept development with teachers, curriculum developers and researchers. The science concept involves the human circulatory system which teachers say is one of the most difficult topics to teach. The intervention activities were constructivist in nature, initiated by eliciting prior knowledge of students before engaging them in real-life experiences and the use of models and pictures.
