EVS Worksheet : Human Body For Class 1 Kids.

Introduction:

Sense organs are specialised organs that help to perceive, sense and feel the world around us. They are an integral part of our lives and it is the only way that enables us to perceive the external environment.

Sense organs provide us with the required data for interpretation through various organs and a network of nerves in response to a particular physical phenomenon. These senses govern our association and our interaction with the environment.

We have five sense organs, namely

Eyes

A good sense of vision is achieved by healthy eyes. Eyes are the organs of the visual system that provide vision and the sense of sight to human beings, animals, birds, insects, fishes, etc. Human beings can have various eye colours depending on the amount of melanin present in one’s body. The eye colour of an organism can vary from brown to blue. However, eyes are sensitive to light.

Ears

Ears are the organs that provide us with the sense of hearing . Hearing or auditory perception is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ called the ear. For example, we hear music through earphones which are inserted into our ears. Total or partial ability to hear is known as hearing loss.

Nose

The organ for the sense of smell is called the nose. Nose has nostrils and we breathe in through the nostrils. The olfactory system is responsible for our sense of smell and the nose is also known as an olfactory organ. Usually, animals have a stronger sense of smell than human beings. However, human beings can also smell thousands of various odours and fragrances. The nose is also an organ which helps us with the sense of taste. For example, we can smell a gas leak.

Tongue

The organ for the sense of taste is the tongue. The tongue has various receptors in the form of buds which can detect whether the item consumed is salty, sweet, bitter or sour. The back part of the tongue detects bitter taste, the front most part detects salty taste, the side part detects sour taste and the middle and front part detects sweet taste.

Skin

The organ for the sense of touch is skin. Skin is the largest organ as it is located throughout the body of the organism . Various receptors are used for different situations like pain, temperature, pressure, etc. For example, when we touch something hot like a hot cup of tea or coffee, we instantly move our hands away from it.

Importance of Environmental Education

• EVS helps children to develop their own insights into the functioning of several things or understanding human processes in their environment. Such interactions with their surrounding environment are immensely important for the healthy development of children.
• Not only does environmental education offer opportunities for experiential learning outside of the classroom, it enables students to make connections and apply their learning in the real world.
• EVS helps learners see the interconnectedness of social, ecological, economic, cultural, and political issues.
• By providing environmental education to students they will engage problem-solving techniques of the outer world to their subjects to understand a particular problem by implying outdoor environmental solutions.
• Environmental Education gives students a new meaning of exploring mother nature to see and resolve the issues which are harmful to the environment and this will also help them in maintaining their own health by doing physical work so that their bodies will be immune from some serious health issues such as short-sightedness, obesity and in some cases even lack concentration.
• The one major issues which we need to deal with is pollution and if we don’t educate our kids about the hazardous effects of environmental damage there will be no future of the world.
