Teaching Procedures
Step1. greetings and lead-in
Lead in the five senses by asking the students about their life experiences. Show the Ss sth like some candies, a stone. Ask the following questions:
1. what’s this?(a candy) with what can you see it?(eyes) sight
2. if we don’t use our eyes, how can we know it is a candy?
---it smells nice. I can tell it by using my smell sense.
3. who would like to taste it? Ask him/her to describe it.
---the candy tastes sweet. I taste it with my tongue.
4. give the student a stone to touch. Ask them to guess what it is, and tell how they can guess it.
--- the stone feels hard and cool when I touch it.
5. can you hear me? With what you can hear me?
---our ears. (hearing)
T: so , we know almost everyone has five senses: sight, hearing, taste, smell and touch. They 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 in fact, there are some people who have lost one or more of their senses. Today, we will learn something about our senses. Please turn to page 1.
Step2 Sharing information
Ask the students to read the instructions and the short passage. Ask them if there are any difficult sentences or phrases. Ask the students to answer some questions:
1. Do you know how blind people read?
(They can read by touching raised dots which represent numbers and letters. This system is called Braille.)
2. How do the deaf communicate with each other?
(They use body language or sign language.)
3. can good senses sometimes confuse us? Yes.
Then ask the Ss to look at the four pictures and answer the questions below them.
P1: if they look at the white part, they can see a vase. black part---two faces.
P2: the two lines are of the same length. The different kinds of arrowheads may mislead our sight. How: A ruler to measure the lines./ cover both ends of the lines.
P3: yes, they are. How: place a ruler next to the line./ to draw more straight lines which run parallel to the lines. Not to be affected by the surrounding lines.
P4: the symbols in line b can be read as the letters K B R M . B/13 4.Can the symbols be read in only one way?
Then ask the Ss to think about them and answer the questions:
Q1: what can we learn from observing the four pictures?
Sometimes even if we have good senses, we can still be confused. So, when judging things, we should try our best to get the real features of the things.
Q2: why are people misled by their own eyes?
Because the background or other lines confuse the eyes. Also, what we expect to see can change what we see. (in fact, the brain is confused and not the eyes.)
Step 3 discussion
Then ask the Ss to discuss the 3 questions below, and to report their answers.
Suggested answers: 1. when we listen to our favorite music, we often close our eyes and just want to listen with our ears. 2. I think in learning english, the sense of sight and hearing help me a lot. I usually listen to the tape before I read. While I am listening to the tape, I will look at the text. And I often read english text aloud. The combination of the two senses helps me remember what I have learnt. 3. Beethoven 貝多芬: composer, deaf in 1818, the ninth symphony Blind Abing: erhu solo, 二泉映月 Hawking: the brief history of time black hole 張海迪：多種語言，會(huì)針灸，《輪椅上的夢(mèng)》 helen keller: “if I had the power of sight for 3 days”
