Module 5 A lesson in a lab
READING & VOCABULARY
What can you see?
I can see a lab in the picture.
What apparatus do we see in
a lab?
Look at the pictures collected by our classmates.
Do you know the name of these equipment？
test tube tongs balance
crucible beaker & glass rod Bunsen burner
Since you are interested in doing scientific experiments,
now let’s get to know some vocabulary and knowledge
related to science and experiment.
Potassium
（钾）
What can it be used for?
How about the following metals?
Sodium(钠) Calcium(钙) Magnesium(镁)
Let’s get to know
more!
Let’s go on getting
to know more metals
Aluninium
（铝）
Zinc
（锌）
Iron
（铁）
Copper
（铜）
⒈Do you want to know more about these metals?
⒉And do you know how we can use these metals
better?
Well, this is what we’ll study very soon.
Now ,let’s come to see how these metals
react with other substances.
At first please read through the passage A
with the tape of it very quickly to try to catch
its main idea . Then finish Activity 2 on page
44 and give your reasons.
The reaction of metals with oxygen
What is the passage A about?
The different uses of metals
The reaction of metals
Skimming
From passage A we can see :
how interesting the experiment about the reaction of metals is!
But do you know :
How we can carry out a chemical experiment in a lab
successfully?
And what is the correct order to describe a scientific experiment?
__________ __________ __________ _________
(1) (2) (3) (4)
aim method result conclusion
Please read passage A very carefully to find
out the answers to the following questions
⒈Which of the metals in the tables reacts the most with oxygen and
water?
______________________________________________________
⒉What happens when you heat calcium in oxygen?
_______________________________________________________
⒊Which metals react with steam?
_______________________________________________________
⒋Does iron have a slow or fast reaction with steam?
_______________________________________________________
⒌Does copper react with water?
_______________________________________________________
Potassium, calcium and sodium
It burns to form an oxide
Magnesium, aluminium and zinc
It has a slow reaction
No, it doesn’t
Careful-reading
Let’s come to see
“A simple experiment”!
Now let’s read through passage B with the tape quickly to fill
in the following table(见课本P45图表）:
实验三部分
实验阶段
Iron in dry
air
Iron in air-free
water
Iron in ordinary
water
Stage A
(starting experiment)
______
nails
oil layer/nails
______
_____
nails
Stage B
(1 week later)
cotton wool
______
oil layer
water/nail
_____
nails
Stage A
(result)
cotton wool
nails
water
water
water
Iron does
not rust
Iron does
not rust Iron rusts
Think over: in the second part of the experiment,why must you boil the water?
And why do you add some oil to the water?
Scanning
Exercise in class:
Finish the following sentences
⒈ In the first part of the experiment, the ______ is dry, not wet.
⒉ It shows that iron _____________ when the air is dry.
⒊ In the second part of the experiment, you must _______ the water
to make sure there is no _______ in it.
⒋ You add ________ to the water because this keeps ________ out of it.
⒌ It shows that ________ does not rust in water that has no ______ in it
air
does not rust
boil
air
some oil air
airnail
Writing:
Since we have known how to do a
scientific experiment , please write
out a complete scientific experiment
report in simple English.
