The aim to be achieved in this research is to increase science learning ha through Team Gamas Tournament learning for class IV students at SDI Perumnas 1. This research uses a type of classroom action research or PTK which consists of two cycles, where in each plant, the source of life on earth is a cycle. consists of two meetings. This type of research is PTK (Classroom Action Research) with four stages, namely planning, implementing observation and reflection. The subjects of this research were 13 class IV students, consisting of 8 male students and 5 female students. Data collection was carried out using observation and test techniques.
