预备课Be a scientist教案
Teaching aims:
1、 discuss what is science.
2、 Inquiry skill
3、 Scientific method
Teaching stress:
Activity: Observe
Teaching steps:
Step one: 导入
Look at the cover of the book, read the title: science.
Talk about what do you know about science.
(life science, earth science,physical science)
Ask: What is science.
Find the answers on page 2.
Ask：Have you ever wondered about the things you see?
是否经常思考？列举身边的问题：
如：空调为什么能使我们凉快？
花的颜色为什么不一样？
月球和地球有什么不同？
Step two: Inquiry skills
科学家首先要提出问题。例如：What do plants need to grow?
课前事先做P13的实验。
分析这个实验（也可以是孩子的实验报告）。
再回到P4，详细分解分析各种skills.
如：Predict: Predict what might happen to the trees when the weather gets colder?
Homework: Let Davy and Alice draw a picture of four seasons.
（回头再附图）
再翻到219页，和222页，对照看一下四季的树和叶子。
(此部分教案，略)

Step four:Story
My First Chemistry Teacher
I will never forget my first chemistry teacher. He was a little man with thick
glasses, but he had a strange way of making his classes lively and interesting.
And his lessons were not easily forgotten.
I still remember one of my lessons from this teacher. After the students were
all in the lab, the teacher brought out three bottles. One was filled with
petrol, one with castor oil and one with vinegar. "Now watch carefully," said
the teacher.
He then filled a cup with some of the petrol, some of the castor oil and some of
the vinegar. As the students watched him quietly, he mixed the three together.
After that, he held up one of his fingers and showed it to the class. He then
dipped it into the cup. After a few seconds he took his finger out. "Now watch,"
he said. "Remember, you must do every thing as I do."
He put a finger in his mouth, tasted it and smiled, looking rather pleased. Then
he handed the cup around the class of students. Each student dipped a finger
into the mixture and sucked it. Instead of smiling, each of them made a face.
The mixture tasted terrible.
When the cup was at last returned to the teacher, he said sadly, "I' m sorry,
none of you watched carefully enough. Yes, I sucked a finger, but the finger I
put into my muth was not the one I had dipped into the cup."
It was my first important lesson as a student of chemistry and I never forgot
it.
