Science Activities Concept Attainment Model The Concept Attainment Model (CAM) is an instructional strategy designed to help students learn by identifying and classifying key concepts through guided inquiry and example analysis. In science education, this model can be especially effective for helping students understand abstract scientific concepts or principles, such as "force," "energy," or "photosynthesis," by examining both examples (positive instances) and non-examples (negative instances). The CAM exhibition was held on where the students did CAM chart. The following is one of the CAM chart.
