Unit 9 When was it invented? Period 2 Step 1 Play a game (1a, 1b: P71) To learn the words about food taste Ask one student to come to the front to do a blind taste test. Show a bag to the students. T: Look, there are 4 kinds of food in it. I will let one of you come to the front and taste them. But I will use a piece of cloth to cover his or her eyes. After tasting, he or she has to tell how each food tastes and what food it is. Are you clear? Sophie, please. Cover Sophie’s eyes and give her the food one by one. Sophie tastes each food and tries to guess what it is. S: It is sweet. I think it is an apple. They are salty and crispy. I think they are potato crisps. It is sour. I think it is a tomato. It is salty. But I don’t think I have eaten this food before. It is delicious. T: Do you enjoy the food? Now you can take off the cloth. The last one is Pizza, which is popular with westerners. You can take it with you and go back to your seat. Thank you. Sophie goes back to her seat. T: Hi, class. What are the four different tastes of the food Sophie had?
