Unit 5 Look into Science
Lesson 25: Let’s Do an Experiment!
I. Learning aims:
Master the new words:
experiment, jar, upside, pour, correct, scientific, method, raincoat, force, pressure, conclude
II. Learning important and difficult points:
1) I cover the top with a piece of cardboard and hold it there.
2) I am so sure of my theory that Brian can do the experiment over your head and I know you won’t get wet.
3) The force of the air keeps the water in the jar.
4) It is strong enough to hold the water.
Language Points:
1. I cover the top with a piece of cardboard and hold it there. 我用纸板把上面盖住然后托住它。
【用法】 句式 cover…with…意为“用……覆盖……”，类似句式be covered with 表示“被……覆盖”，这是一个系表结构。
【举例】①My mother covered the table with cloth. 我妈妈用布把桌子盖住了。②The bed is covered with paper. 床上盖满了纸。
