CBSE Class 4 Science Syllabus

CBSE Class 4 Science:

      CBSE Class 4 Science covers the following topics such as

  1. Plant life and animals
  2. Human body
  3. Food and nutrition
  4. Clothes, safety and first aid
  5. Our environment and our universe
  6. Our family
  7. Our society
  8. Force, work and energy

These are the various topics that are covered in the CBSE Class 4 Science stream. Let us check these topics in detail below. Note that these topics are not given in the form of sequential chapters.

 

  1. Plant life and animals:

               Any plant consists of roots, stems, leaves and may produce fruits or vegetables. Any green leaves of the plants prepare their own food with the help of the process called as photosynthesis. Roots absorb water and other important minerals from the soil. Stem helps in carrying this minerals and water absorbed by the roots to the various parts of the plant. Not only that, they also help in carrying food from the leaves to the other parts of the plants. It stores excess food and gives support to the plant.

              The sub topics which are covered under this are adaptation, making food by plants, uses of plants, dispersal of seeds and parts of the plants. Similarly, every animal has unique characteristic and feature. Every animal is different and may have different organs such as long or short tail, with or without horns, lengthy ears, color and pattern, etc all differ from one animal to another.

              For example, rabbits or bunnies have long ears whereas we cannot see ears in the birds such as parrots or crows, etc. Animals like tigers, zebra, and giraffe have specific pattern and color in the skin tones and every animal varies greatly in shape and size. Thus, the sub topics which are covered under this are birds, useful animals for the environment, adaptations and reproduction in animals, etc.,

The important organ systems in our human body are:

  • Digestive system:

       Human digestive system is a series of organs which are responsible for converting the foods consumed into essential nutrients that are absorbed into the body and eliminates unused waste materials. Only if digestive system of a human body functions properly, the foods consumed will be converted into essential nutrients and wastes are properly released.

  • Circulatory system:

             Circulatory system is a network with number of organs and vessels that are responsible for carrying blood through cells, segregation of hormones, passing oxygen and other important gases to and from the cells, etc. Without circulatory system the body will fail to fight against the diseases and human body becomes more vulnerable to any kind of diseases.

  • Respiratory system:

         This is an important system in the human body which is responsible for inhaling oxygen and exhaling out carbon dioxide. The primary and most important organ of an respiratory system are lungs which are responsible for this exchange of gases as we breathe.
