The research aims to identify the effect of the strategy of imagination, organization, focus, sharing, and publishing on the scientific attitudes of fifth-grade science students. To achieve the research objective, the researcher adopted the experimental approach. A sample of 61 students from Al-Shatra Preparatory School for Boys was chosen. The sample was split into two groups: 30 students were selected as the experimental group, taught by adopting the strategy of imagines, organize, focus, share, and publish; 31 students were the control group who followed the traditional method in learning. The researcher developed a scale to measure the scientific attitudes of the research sample, in addition to an achievement test. The results showed

vacuum micro- valves(GI-19b) through activating their internal surfaces by the
use of ionic pumping which is used for treating valves which are out of order
