    Multimedia contributes to a well-equipped, interactive, and student-centered learning environment. Integration of multimedia into science education can enhance students’ achievement and motivation to learn. This study attempts to find out which multimedia tools are more effective for students, to investigate the challenges and barriers teachers face in integrating multimedia into science classrooms, and to examine the motivation and attitudes of students. A one-group quasi-experimental design was used. The same group of students were taught using images in control condition and later with both images and videos during experimental conditions. Data was collected through both quantitative and qualitative methods using unit tests, observations, and questionnaires.
