How do we know whether a dish is delicious? (We taste it with our tongues.)
How do we know that a flower has a pleasant smell? (We smell it with our noses.)
What do we do when we want to know whether the water in the basin is hot or cold? (We put our hands in the water to feel it.)
How do we know about the world around us? (We usually use our five senses. They are sight, hearing, taste, smell and touch.)
Ask students more questions if time allows. While doing this, write down the following words on the blackboard. Students will be familiar with some key words or new words in the short passage.

As we all know, almost everyone has five senses, which are used everywhere and all the time. We learn about the world through the five senses. We use the five senses to study, work and relax, but there are some people who have lost one or more of their senses.
A person who cannot see is blind and someone who cannot hear is deaf
Write the words 'blind' and 'deaf' on the blackboard.
Do you know how blind people can read? (They can read by touching raised dots which represent numbers and letters. This system is called Braille.)
Write 'Braille' on the blackboard.
How do the deaf communicate with each other? (They use body language or sign language.)
Write the words 'body language' and 'sign language' on the blackboard.
Sharing information
1 Have students read the instructions and the short passage. Ask them if there are any sentences that they don't understand. Have them give more examples of different senses affecting one another. (People have trouble recognizing tastes when the food is the wrong colour. For example, red 7-UP will taste like cherry soda. Sometimes food of a strange colour, for example, bright green biscuits, appears not to taste good.)
Then ask students to look at the four pictures and answer the question below each picture.
Picture 1
Ask students what they can see in this picture. (If they look at the white part, they can see a vase. If they look at the black part, they can see two faces.)
Picture 2
Ask students how they would find out whether the two lines are of the same length. (They can use a ruler to measure the two lines. Or, they can use two pieces of paper to cover both ends of the two lines.)
Picture 3
Have students say how they can prove that the two lines are straight. (They can place a ruler next to the lines. They can also use a ruler to draw more straight lines which run parallel to the two lines.)
Picture 4
The symbols in Line b can be read as the letters K, B, Rand M, or K, 13, Rand M.
After students have studied the four pictures, have them think about and find the answer to the following question:
