• There are statistically significant differences between the mean scores of the experimental group and the control group in the post  application of the scientific concepts test in favor of the experimental  group.
• There are statistically significant differences between the mean scores of the experimental group in the tribal and post application of the scientific concepts test in favor of the post  application.
• The research presented a set of proposals, including holding continuous training courses for teachers in modern teaching methods, including the Merrill and Tennyson model.
