Teacher Support Materials (TSM) was developed to enhance the conduct of Science Investigatory Project (SIP) in Schools. This support material addresses the problems encountered by teachers in integrating Science Investigatory Projects (SIP) in teaching science because of the lack of skills, competence, and training as revealed in the result of the survey conducted by the author. This material contains five teaching approaches integrating inquiry skills and values in science. These teaching approaches include Inquiry Approach, Project -Based Learning, Practical Work Approach, Cooperative Learning, and Discovery Approach. Also, it includes IP-based lessons adopting teaching approaches integrating inquiry skills and values in science. IP-based lessons are for different year levels in favour for both biological and physical science teacher-users. The description of the very important details in the different parts in conducting investigations is also found in this support material. The support materials would guide the teachers in their quest in improving science education.
