Environmental problems can be addressed in various ways, one of which is through education. The purpose of this study is to develop student worksheets based on the Discovery Learning model used for students at the Early Childhood Education, Elementary School, Middle School, and High School levels. The method used in this study is research and development with the ADDIE development stages (Analyze, Design, Develop, Implement, and Evaluate). The results of this study indicate that the student worksheet product integrated with Discovery Learning is suitable for use in learning. The topic of terrestrial ecosystems is important because insight into terrestrial ecosystems needs to be introduced to students from an early age.
