Developing a student's interest in science and technology is one of the objectives of science education. It provides a concrete basis for conceptual thinking, which motivates students to learn more. To understand the concept of the human heart and the excretory system of human beings, students of grade 7 enthusiastically performed various activities by creating working models, still models, and colorful charts. Our young learners presented a detailed explanation of their project. This activity's objective was not only to inculcate a scientific attitude and research-mindedness but also to create teaching aids that helped students understand the cognitive, affective, and psychomotor aspects of the task. Teaching aids created by our Presidians worked as a very effective tool to make the classroom experience of the students very real and meaningful.
