Student worksheets can play a significant role in facilitating active learning on these topics. This research aims to determine and describe the validity of the "Dunya Hejo (Du-Jo)" E-Worksheet on climate change and global warming. The research method used is the Educational Design Research Plomp model. There are 3 research stages, but this research only consists of 2 stages, namely the initial investigation stage and the design stage. Because this research only describes the validity of the "Dunya Hejo (Du-Jo)" E-Worksheet. Validation was conducted by two media experts, two material experts, and five teachers. This e-worksheet will be used by high school students in class X. Validation results from the experts and teachers indicated that the "Dunya Hejo (Du-Jo)" e-Worksheet received excellent ratings for software engineering, visual communication, and learning design.
