Sense Organs for Class 2 Science
In this concept, the students will learn about sense organs. They will also get an idea about the five sense organs and their functions.
After reading the concept, students will be able to:
- Understand how the sense organs in the human body help in body coordination and movement.
- Recall the roles of different sense organs such as ear, nose, eyes, skin, and tongue.
Each concept is explained to class 2 students using descriptions, illustrations, and concept maps. After you go through a concept, assess your learning by solving the two printable worksheets given at the end of the page.

- We have several organs in our body, each for a specific function.
- Five sense organs work together and help our body respond to changes around us.
- In this module, we will learn about the sense organs and their functions.
How Do We Sense Things?
- Our body has specialised organs that coordinate with the brain and help us sense changes around us.
- For example, our eyes get closed automatically when light intensity is high. It happens because our eyes sense the bright light, and the brain commands them to shut
Sense Organs:
- We and all other animals have a pair of eyes.
- The eyes help us to—
- Look at things and identify them.
- Identify different colours.
2) Ears:
- We can hear sounds with the help of the ears. We have a pair of ears, one on each side of the head.
- The outer part of the ear is flexible and collects the sound waves, which are transferred to the inner ear.
- Functions of the ear are—
- Help us to hear.
- Help in balancing our bodies.
3) Skin:
- Skin is the largest organ that covers our whole body.
- It has the following functions—.
- Sensing the characteristics of objects around us like hot and cold, smooth or rough, etc.
- Protecting the internal parts of the body.
4) Tongue:
- The tongue is situated at the base of our mouth cavity.
- It is made of muscles and is flexible.
- The tongue helps us—
- To identify different tastes.
- To sense the temperature of the food, like hot or cold.
- To speak properly.
- To chew the food.
5) Nose:
- We have one nose in the centre of our face between the eyes.
- It is specialised in the sense of smell.
- It performs the following functions—
- It helps us to differentiate and identify different scents.
- It helps us in breathing
Care of Sense Organs:
- The sense organs are essential for the proper functioning of our body.
- They are delicate organs, and hence we should take good care of them.
- Sit at an appropriate distance while watching the TV, mobile phone, or laptop.
- Restrict your screen time.
- Do not insert any sharp objects into the eyes, ears, or nose.
- Do not allow water to enter the ear as far as possible. Clean it with a soft cloth in case it enters.
- Never leave an open wound on your skin.
- Clean the tongue regularly.
- Bathe daily to keep your body clean.
New Words:
Temperature: Hotness or coldness of a substance.
Specialised: Something which has a particular function to perform.
Did you know?
- A chameleon can rotate both eyes separately in any direction. So, it can see its front and back together.
- Out of all human senses, the sense of hearing is the most powerful and the fastest one.
- Tiny hairs on the ear's inner lining naturally push the ear wax out of the ear.
