This document provides information about the five senses - taste, touch, smell, hearing, and sight. It discusses the organs and body parts involved in each sense. For taste, it describes how the tongue contains taste buds that identify flavors. For touch, it notes that the skin and nerves receive sensory information. For smell, it explains how the nose and olfactory nerve detect scents. For hearing, it mentions the ear and how sound vibrations are perceived. And for sight, it outlines how light enters the eye and the retina forms images that the optic nerve relays to the brain. The document includes questions and activities to help teach about each of the five senses.

2. THE FIVE SENSES
What are the five senses?

3. THE SENSE OF TASTE
• In this lesson we are going to
learn about the sense of taste.
• Question: Do you know in which
organ the sense of taste is?
• Let´s see the following picture
The tongue is covered in small spots called taste buds. These taste buds identify
flavours and have nerves that send information to our brain.
As you can see in the picture, the tongue is divided in four flavours:
BITTER, SOUR, SALTY AND SWEET.
Questions: What different flavours do you know? Which are your favourite tastes?

4. - Did you know that the sense of taste is connected to the
sense of smell? Does food taste the same when we have
a cold and can´t breathe properly?
- In pairs draw a chart in your notebook and write some
examples.
BITTER SOUR SWEET SALTY
- Share the answers with the class.
• A healthy tip! Brush your teeth three times a day and
brush your tongue too to keep it germ-free.

5. THE SENSE OF TOUCH
• The skin is the largest organ in the body and is responsible for this
sense.
• Our skin is covered with hair and small pores that release sweat.
• There are also lots of nerves too that receive information from what
we touch and send it to the brain.
What organ can you see?

6. • The students touch different objects and they have to say if they are:
soft, smooth, hard, rough, cold…
Other activity…
On the other hand…

7. • We could make the students touch different objects and we introduce all the
objects in a large bag.
As a complementary activity…
• The pupils will be blindfolded and will have to guess what the object is and
say what type of touch it has.
• How does it feel? Is it soft or hard? Is it smooth or rough? Is it cold? Is it
warm? Can you describe the object?

8. THE SENSE OF SMELL
SMELLING…
What sense is she using?

9. - What organ can you see?
- What is it for?
- What does the olfactory nerve send to the brain?
• Air gets in through the nostrils. Inside our nose, the
olfactory nerve gets information from the air and sends
it to the brain.
Let’s see the following picture:

10. - What smells do you like?
- Do you like the smell of petrol?
- Do any smells remind you of anything?
Copy the following words and write what smell they make you think of:
