In order to make the students become ecstatic during the learning process, it is a need to do the edutainment approach. Therefore, it is a necessary to do an observation with a purpose to produce the product in a form of interactive multimedia named science edutainment with the topic of earth that is applicable and valid for seventh grade of junior high school students. This research used 4D method without dissemination step. The applicability of the developed product is obtained from the validation of product and the readability test. According to the results of media validation done by the expert, the media was considered appropriate by the percentages of 76.4% for media appropriateness and 88.5% for content appropriateness. On legibility test, it obtained 91.3% by teachers and 93.5% by students, which mean that the media was very appropriate. Hence, the interactive multimedia of science-edutainment on earth topic for the 7^th graders of Junior High Schools is considered appropriate and valid.
