<![CDATA[According to experts in design, materials, language, and education, as well as students and teachers, the primary goal of the research was to create a product that could be used as a supplemental science lesson plan for the “Changing Forms of Energy” unit in fourth grade public elementary schools. A research and development approach that has been adapted from 4-D is used in this research. Among the three validators participating in the study, design experts achieved a 96% success rate with the “Highly Valid” criterion, material experts achieved a 90% success rate, and language experts achieved a 90% success rate through validation. The results of the development trial activities confirmed these findings; The first teacher's response was rated "Very Good" by 98% of students, while the second teacher's response was rated "Very Good" by 94% of students. The proportion of students meeting the "Excellent" standard on the student response exam was 93%. According to the results, fourth graders were eager to learn more about the supplemental science curriculum. Therefore, additional science lesson plans are practical to use in the classroom.]]>
