brainstorming

how can we know whether a dish is
delicious?
how can we know that a flower has a
pleasant smell?

whether the water in the basin is hot or cold?
how do we know about the world around us?
the five senses are:
the sense of sight , the sense of hearing , the sense of taste , the sense of smell and the sense of touch.
they enable us to know the world around us.

step 2:  dealing with the short passage on the text(page1)
do you know how blind people can read?
they can read by touching raised dots which represent numbers and letters. this system is called
write the words “blind” and “deaf” on the blackboard.
write “braille”on the blackboard.
look at the four pictures and answer the question below each picture
• what can you see in this picture?
• how would you judge the length of the two lines?
• how can you prove that the two lines are straight?
• can the symbols  be read  in only one way?
• why are people misled by their own eyes.
• picture 1
• if they look at the white part, you  can see a vase,if you look at the black part, they can see two faces.
• picture2
• you can use two pieces of paper to cover both ends of the two lines

• picture3
• they can place a ruler next to the line. they can also use a ruler draw more straight lines which run parallel to the two lines.
• pictures4
• k b r m, or k,13,r,m

step 3: sharing information and observation
show ss some pictures12
why are  people mislead by their own eyes?
because the background or other lines confuse the eyes.
also ,what we expect to see can change what we see. 
actually, the brain is confused  and not the eyes.

step 4:   discussion 
• read the three questions in the short passage and discuss them in groups of four.
• report your answers to the whole class.
• we often use one or two of the five senses more than the others when we need to . for example,in the darkness, the sense of haering and the sense of touch become more sensetive bacause we cannot see anything, when we listen to our favourite music, we may close our eyes and just listen with our ears.when we eat something, we not only taste or smell it, but look at it as well.
• i think that when learing english, the sense of sight and the sense of hearing help me a lot. i usually listen to the tape before i read. while i’m listening to the tape, i’ll look at the text. and i often read iit aloud. the combination of the senses best helps me  remember what i have learned.
