Senses: TOUCH

The skin is the organ of touch. It is the largest organ. We use our skin to identify if something is hot or cold (temperature), hard or soft, smooth or rough (texture).

Our body is covered in skin which has nerve endings that pick up information and send it to the brain.

In some parts of our skin we have more nerve endings so they are more sensitive like the palms of our hands or the soles of our feet.

The skin is made up of three layers:

The epidermis: Melanin is here.

The dermis: Nerve endings, blood vessels and sweat glands are here.

The subcutaneous layer: Hair follicle and fat are here.

FLYERS EXAM

 The FLYERS EXAM is similar to the Movers exam you practised last year.

Here you have an example to get to know the listening, reading,  writing and speaking activities from a FLYERS EXAM.

Have a look at it at home!

Senses: HEARING

The ear is the organ of hearing.

The ear is made up of three different sections: the outer ear, the middle ear, and the inner ear. These parts all work together so you can hear and process sounds.

VIDEO to explain how the ear works.

PARTS OF THE EAR:

HOW THE EAR WORKS
A sound wave comes in from the outside. It is collected by the pinna and enters the ear canal.

After it passes through the outer ear the sound waves strike the ear drum.

Then, the sound waves hit the ear drum and make it vibrate. This vibration moves the hammer, then the anvil and finally the stirrup.

Then the stirrup moves and pushes against the cochlea.

In the cochlea, sound moves as a wave creating vibrations.

The cochlea contains fine hairs that are moved by the sound waves. This movement of the hairs causes electrical impulses that travel up the auditory nerve to the brain.

The brain makes sense of the signals and tells us what we can hear.

QUIZ: TASTE

YES/NO QUESTIONS

         1-  Is the tongue a bone?

         2-  Is the tongue flexible?

         3-  Does your nose help you to taste food?

         4-  Can gustatory nerves detect special chemicals?

-WH QUESTIONS

        1. What is taste?

        2. What do we use our tongue for?

        4. What are taste buds?

        5. What do gustatory nerves do?

 

Senses: TASTE

The tongue is the organ of taste.

It is made up of many groups of muscles. It is very flexible so you can say words and also helps you eat.

The tongue is rough and bumpy because it is covered with taste buds, so you can taste everything. Your nose helps you taste foods by smelling them before they go in your mouth.

taste buds seen through a miscroscope

People are born with about 10,000 taste buds. Taste buds can detect special chemicals in the things that you eat and drink: sweet, sour, bitter, salty and umami.

  

The gustatory nerves transmit the impulses that the taste buds produce to the brain. And finally the brain interprets the information.
