We designed a microbial science popularization product based on virtual reality technology, "Micro World -- Exploring the Microbial Kingdom," and conducted usability tests. Participants used head-mounted VR glasses to experience virtual scenarios teaching microbiological knowledge. The product's user experience was evaluated through a User Experience Questionnaire (UEQ), and the results showed that our product provided both usefulness and enjoyment. In addition, the quality of participants' relevant knowledge acquisition was measured using the Student Education of Educational Quality (SEEQ). The SEEQ results show that "Micro World" is an effective tool for popularizing microbiology science and can actively promote students' independent learning and improve learning quality.
