Sensory Organs

Sensory organs are specialized body parts that allow living organisms to perceive and respond to the environment. In humans, the five main sensory organs are the eyes, ears, nose, tongue, and skin.

Eyes

The eyes are the sensory organs responsible for vision. They contain photoreceptor cells that detect light and enable the brain to interpret visual information.

Ears

The ears are the sensory organs responsible for hearing and balance. They contain the cochlea for hearing and the semicircular canals for balance.

Nose

The nose is the sensory organ responsible for the sense of smell. It contains olfactory receptors that detect different odors and send signals to the brain for interpretation.

Tongue

The tongue is the sensory organ responsible for the sense of taste. Taste buds on the tongue detect different flavors such as sweet, sour, bitter, and salty.

Skin

The skin is the sensory organ responsible for the sense of touch, temperature, and pain. It contains various receptors that detect pressure, temperature, and pain signals and send them to the brain for processing.

Vocabulary/Answer key

What is science?

The resources above cover the following skills:

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).

EARTH AND SPACE SCIENCE

Earth’s Systems

Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
