Critical thinking skills needed to face the 21^st century. PISA 2018 data shows that students' critical thinking skills are still low. The Earth is experiencing an increase in temperature so it requires a solution to overcome it. STEM animation learning media with feedback can increase student reality and involvement and make it easier for students to understand concepts by linking STEM elements. The application of STEM learning media animation with feedback is still rarely used to build capabilities of critical thinking. The purpose of this study was to develop STEM animation learning media with feedback to facilitate students' critical thinking skills on appropriate global warming materials. This study uses Research and Development and ADDIE model's 5 stages, namely Analysis, Design, Development, Implementation, and Evaluation. The instrument used is a media validation questionnaire, material, and readability. The results of average percentage of test material 95,1 % and media 94,3% with very decent criteria. The percentage of students' readability test has an average value of 81% with a very decent category. So, this media can facilitate students to think critically on global warming material. For future researchers, it is recommended to use the product as a medium of learning in the classroom.
