Study Notes

Science Class 6 Ncert

The NCERT (National Council of Educational Research and Training) curriculum is followed by many schools across India, providing a standardized education system for students from various backgrounds. This curriculum covers a wide range of subjects, including science, which plays a crucial role in helping children understand the world around them.

Living Organisms

At the elementary level, the study of living organisms helps students develop an awareness of the diversity of life forms and their basic characteristics. They learn about different types of organisms, such as plants and animals, and understand how they interact with one another and their environment. Some key concepts covered under this topic include:

  • Classification of organisms: Students learn about categorizing organisms based on common features into groups like bacteria, fungi, protists, plants, and animals.

  • Habitats: Understanding where these organisms live and their requirements for survival is also important.

  • Interdependence between organisms: Concepts like predators, prey, producers, and decomposers help create an understanding of how species influence each other.


Light is another fundamental concept taught in science classes. In grade six, students are introduced to light sources (like candles, bulbs), its properties (reflection, refraction), and its effects (shadow formation). Key concepts include:

  • Properties of light: Understanding what makes light travel straight in a vacuum and why it bends when it passes through glass.

  • Shadow formation: Learning how objects block out part of light source creating shadows.

  • Reflection and refraction: Concepts needed to explain phenomena like rainbow; reflection of light from smooth surfaces like mirrors.


The study of electricity starts in grade six with an introduction to electric circuits. Children learn about conductors (wires), insulators (plastic), motors, generators, and batteries. Basic electricity terms are introduced, such as voltage, current, and resistance. By exploring simple experiments involving circuits using flashlights and buzzers, students gain hands-on experience while learning about energy transfer through electrical paths.

Explore key concepts of living organisms, light, and electricity as per the NCERT Class 6 curriculum. Understand the classification of organisms, habitats, properties of light, shadow formation, electric circuits, conductors, insulators, and more.
