Learning through senses of taste, hear, and touch can help us discover new things everyday. The five senses altogether help us see nature around us. How do they work?
You can learn how the five senses work in our bodies in this Spanish lesson. Also, it’s great to incorporate the Spanish bilingual terms. When we learn through our senses, we can experience the world around us in an amazing way.
What are the learning though the senses of taste, hear, and touch? In this lesson, you’ll learn the basic information about the sense of taste, hearing, and touch. Once you know the brief science background, you can use the diagrams and free worksheets to practice what you’ve learned.
You can also pair this lesson with the five senses in Spanish for kids. This way you have a comprehensive ESL lesson to teach children about the basic knowledge of our five senses.
Brief science background:
The sense of taste
Our tongues present small, microscopic cells that allow us to detect a variety of tastes. The different tastes: sour, sweet, salty and acid are all part of the tongue.
The front, middle, sides, and back parts of the tongue can detect different flavors in foods and drinks. The front part of the tongue can identify sweet foods. The middle section can detect salty foods.
The sides of the tongue can detect acid foods. The back area of the tongue can identify sour foods. As soon as babies are born, they are able to use their sense of taste to explore their surroundings.
The sense of hearing
Our ears are the body parts that allow us to listen all types of sounds. The ear is composed of the outer, middle, and inner parts. The outer ear has many specialized regions, which allows sound to enter into the ear.
The tympanic membrane, located between the outer and middle ear regions, receives the sound waves. Within the middle ear, the auditory tube or Eustachian tube, sits in the tympanic cavity, regulating the pressure variations between ear and throat.
The middle ear also has 3 ossicles or small bones: the malleus (hammer), the incus (anvil), and the stapes (stirrup). These minuscule bones work together to allow the passage of sound from the middle ear with much greater amplification.
The inner ear contains the cochlea, the vestibule, and the semicircular canals. The cochlea has a spiral, snail-like shape. It consists of the organ of Corti, which is considered as the receiver for the hearing sense. The many sounds that we can hear are also associated to the many aspects that we perceive from our surroundings.
Some of the sounds we hear are loud noises and soft noises. Fire trucks and ambulances have loud sirens that can alert people about an emergency.
But birds and other animals can sing sweet songs. At a zoo, we can discover different sounds. An elephant can use its trunk to blow, a lion can roar, or a monkey can shriek to call its young.
From bells to dogs barking to someone calling our name, sounds can describe how our environment is made of various levels of noises.
The sense of touch
The skin is the most protective outer layer in our bodies. It protects the internal organs, bones, muscles, and other internal parts.
The skin in the body, as part of the five senses, have specialized receptors and nerve cells that allows us to perceive changes in temperature, textures, and injuries.
The skin is made of several layers: epidermis, dermis, and hypodermis. The upper layer is called the epidermis. Underneath that, the dermis layer is found. The innermost layer is called the hypodermis.
Within the outermost layer of the epidermis, the hair follicles and sweat pores are located. The dermis has the Ruffini corpuscle and the Krause corpuscles sensory receptors. The Ruffini receptors can detect changes in temperature such as heat.
The Krause receptors can detect changes in temperature such as cold. The hypodermis contains the Vater-Pacini corpuscles, which can detect changes in pressure and variations in vibrations.
The skin is a delicate structure that can easily be cut, bruised, burned, and even sunburned. Antiseptics and medications can heal the skin from cuts, burns and bruises. But sunscreen is the most powerful skin protectant against harmful UV rays that cause sunburns.
You can learn about these senses when you can actually recognize different tastes, sounds, and touches. In this learning activity, you’ll learn how to make a collage.
