The study aimed to identify the effectiveness of the multiple intelligences and the scientific imagination strategies in improving the achievement among the fifth-grade students in science, and the quasi-experimental design was used. The experimental group consisted of (37) students, and the control group consisted of (42) students. The results showed; the bodily, visual, and linguistic intelligences levels were high, meanwhile, the levels of logical, social, intrapersonal, musical, and naturalistic intelligences were low. Accordingly, the experimental treatment employed the activities of bodily, visual, and linguistic intelligences, in addition to the scientific imagination. Moreover, the results showed; the effectiveness of the two strategies in improving the bodily, visual, and linguistic intelligences, the scientific imagination, which in turn enhanced the achievement in a science subject.The results indicated that the interaction between visual intelligence and scientific imagination, and the interaction between linguistic intelligence and scientific imagination explained (47%) of the variance in achievement. The researchers recommended applying the multiple intelligences and the scientific imagination strategies in teaching students.
