Short video platforms like Tik Tok are becoming an increasingly crucial educational platform that fosters learning on demand with educational science videos. Educational videos are perceived as a productive strategy to enhance the users' scientific knowledge and even are applied in some academic scenarios. This study provides an overview of science communication videos on Tik Tok information management and assesses the content topics based on user engagement, time, creator, and textual features. Seven main content topics are identified: Healthcare, Trivia, Nature, Astronomy, Social Science, Engineering, and Agriculture. Further findings demonstrate that topics vary significantly in terms of user engagement features: Topics on Healthcare and Trivia receive more likes, comments, and shares, whereas Social Science, Engineering, and Agriculture attract fewer engagements. Moreover, videos on the Healthcare topic have shorter durations, more followers, more concise video titles, and a smaller number of hashtags. We further elaborated on each topic, combined with the existing literature on related fields of information management.
