CBSE Solutions for Class 7 Science

Science in Class 7 helps students explore the fascinating worlds of Physics, Chemistry, Biology, and Earth Science through practical activities and real-life examples. Concepts such as acids and bases, electricity, metals and non-metals, physical and chemical changes, adolescence, heat transfer, motion, life processes, light, and the solar system may seem challenging at first. To help students master these topics, we provide clear, step-by-step CBSE Class 7 Science Solutions for every chapter in the CBSE textbook, Curiosity.

While our solutions provide clear and accurate answers, the Naitri app offers an innovative way to learn. Using Augmented Reality (AR), students can explore interactive electric circuits, 3D models of living systems, visual demonstrations of heat and light, scientific experiments, and models of the Earth, Moon, and Sun, transforming their textbook into an engaging 3D learning experience.
