Science literacy is highly important for students as it enables them to comprehend the issues present in the community's environment. Students' science literacy skills can be enhanced through science learning that prioritizes the development of attitudes, ideas, and process skills. The learning process should be designed in such a way that students can explain scientific phenomena, evaluate scientific research, and interpret data and scientific evidence. This research aims to describe the effectiveness of the project-based learning (PBL) model with digital storytelling in improving 10thgrade students' science literacy on the topic of ecosystems. The research adopts a quasi-experimental design with a non-equivalent pretest-posttest control group. It was conducted at Al Manshuriyah Islamic High School, involving 57 students from two science classes, IPA1 and IPA2. The experimental group, IPA1, was taught using the project-based learning model with digital storytelling, while the control group, IPA2, was taught using conventional teaching methods. The research instruments underwent validation and evaluation by experts to ensure their suitability. The study's results showed that the learning process made students more actively engage in creative problemsolving. There was an improvement in students' science literacy skills on the topic of ecosystems, with an N-gain score of 65% in the experimental group and 56% in the control group. The percentage of students achieving a good category in science literacy was 85% in the experimental group and 78% in the control group. Students' caring attitude towards the environment reached an excellent percentage of 79%. In conclusion, the researcher found that project-based learning with digital storytelling effectively enhances students' science literacy skills and promotes environmental awareness.
