chemistry atomic structure model with acid base using cardboard diy howtofunda class 9

periodic table model 3d making, in this course is designed to help students understand the structure and organization of elements in an interactive and engaging way. In this course, learners create a three-dimensional model of the periodic table using materials such as cardboard, thermocol sheets, colored paper, and labels to represent different elements and groups. The model highlights how elements are arranged according to their atomic number, periods, and groups, making it easier to visualize trends like valency, reactivity, and classification into metals, nonmetals, and metalloids. By building this 3D model, students can clearly see the logical order and periodicity that forms the foundation of chemistry. The course also emphasizes the significance of the periodic table as the “map of chemistry” that helps predict the properties of elements. This hands-on project fosters creativity, scientific thinking, and problem-solving skills, making it an excellent activity for science fairs, classroom demonstrations, and interactive learning sessions. howtofunda
