This topic explores the human body and its movement.
Introduction to CBSE Class 6 Science Chapter "Body Movements"
“Body Movements” in CBSE Class 6 Science offers students a detailed look at the mechanics of movement. The chapter covers various types of joints in the human body, such as fixed, pivot, ball and socket, and hinge joints, explaining how these joints enable different kinds of movements. Students learn about the human skeleton, which provides structure and support, the skull that protects the brain, and the rib cage that shields the heart and lungs.
The chapter extends the learning to animal movements by explaining how different animals use their bodies to move from one place to another. It discusses the movement of fish through water, birds through the air, and the unique aspects of snail locomotion. The concept of streamlined bodies in fish and birds is introduced, showing the correlation between body shape and ease of movement. This chapter not only covers the biological aspect of movement but also instills a sense of wonder about the diversity of life on Earth.
Assignments for CBSE Class 6 Science Chapter “Body Movements”
- Joint Flexibility: Observe and note down the movements you can perform with different joints in your body.
- Animal Observation: Watch a pet or local animals and describe how they move differently than humans.
- Skeleton Sketching: Draw a human skeleton and label the types of joints and major bones.
- Bird Watching: Observe birds in flight and note how they use their wings and body shape to glide through the air.
- Comparative Analysis: Compare the movement of a fish in water with a bird in the air, focusing on the similarities and differences in their locomotion.
Conclusion
The CBSE Class 6 chapter “Body Movements” provides invaluable knowledge on the complexity and beauty of movement in living organisms. By understanding how our bodies and those of other animals are designed for movement, students gain a deeper appreciation for the intricacies of biology and the natural world.

Questions and Answers for CBSE Class 6 Science Chapter "Body Movements"
- Q1: What enables different kinds of movements in the human body?
ANS: The different kinds of movements in the human body are enabled by various joints and the coordination between the skeletal and muscular systems. - Q2: How do the skulls and rib cages of humans function?
ANS: The skull protects the brain, and the rib cage safeguards the heart and lungs from damage. - Q3: What is the role of joints in body movement?
ANS: Joints act as fulcrums, allowing the muscles to act like levers to move the body. - Q4: How do fish move in water?
ANS: Fish move in water by flexing their bodies and tails to push against the water, often aided by their fins. - Q5: What type of joint allows for the greatest range of movement?
ANS: The ball and socket joint allows for the greatest range of movement, as seen in the shoulders and hips. - Q6: Why do birds have streamlined bodies?
ANS: Birds have streamlined bodies to reduce air resistance, which makes it easier for them to fly efficiently. - Q7: What is a hinge joint, and where is it found in the body?
ANS: A hinge joint allows for back-and-forth movement, similar to the opening and closing of a door. It’s found in elbows and knees. - Q8: How does the snail move?
ANS: A snail moves by gliding over a layer of mucus that it secretes, using muscular contractions along its belly, known as the foot. - Q9: What is the function of the streamlined shape in fish?
ANS: The streamlined shape in fish helps to minimize resistance as they move through water, allowing for faster and more efficient swimming. - Q10: Can you give an example of a fixed joint and its function?
ANS: Fixed joints, such as those found in the skull, do not allow movement. They function to protect the brain and support the structure of the head.
