Jingle Bells Cross-curricular connection| Biological science* Parrots are very intelligent birds, and they can even learn how to talk. Let’s find out how to train a parrot to say words. Parrots are popular pets. They are social and intelligent birds. They have the ability to mimic (模仿) human speech and we can teach them to talk! Training your parrot • Put your parrot’s cage in a calm and quiet place. • Hold a treat in front of the bird and begin with a simple word like “hello”. Look at your bird and say “hello” in a bright and positive voice. Repeat the same word multiple times. • When your parrot starts making a sound like “hello”, give it lots of praise and a treat. Say the word back to it in an excited and loud voice. • When your parrot can say “hello”, move on to teaching it the next new word!

When your parrot can say “hello”, move on to teaching it the next new word! 佳句回顾 3. 如果这只鸟看起来很疲惫或没兴趣,就别打扰它。 _ 4. 只有当你的鹦鹉发出与你试图教的单词相似的声音时,才给它喂食奖励。 _ If the bird looks tired or not interested, leave it alone. Only give your parrot a treat when it makes a sound similar to the word you are trying to teach. What animal would you like to keep as a pet? In this project, you are going to make a class pet booklet. Making a pet booklet Step 1 Discuss and choose an animal that would make an interesting pet. Step 2 Research key information about the animal and make notes. Use the following questions to help you. • Why do people like to keep this pet? • How should people take care of it? • What is your experience of keeping this type of pet? Step 3 Each group writes a page for the animal. Organize the information into sections and choose the most important or interesting facts for each section. Then find pictures or create your own. You may refer to the example below. Step 4 Collect the pages from the different groups and make a class pet booklet. Write a contents page and design a cover. 我们可以通过一个人对待动物的方式,来判断他的内心。 —— 伊曼纽尔・康德(德国哲学家) 基础作业: 小组合作完成项目式学习,设计自己的宠物手册; 小组合作准备班级分享活动。 拓展作业: 欣赏其他小组的作品,修改和丰富本小组的作品。 Thank you! 28 Lavf54.6.100 null 136312.42 $
