Water教案1

module 1 the natural

unit 3 sea water and rain water

一、分析(unit analysis)

(一)地位(unit position)

have you ever seen…? 的句型在6a,6b中都已出现,但作为知识难点,教师在学习过程中还要再复现与强调。

作为情感态度发展的目标,教师要对学生进行节约能源的教育。

(二)重点(unit points)

1 关键词:

关于海洋生物的介绍:a coral reef, seaweed, dolphin, shark, intelligent.

2  功能:

用what/why/where/when/who/how…?询问对方,获取信息。

3 语法点:

use for doing sth. we can save water by doing sth. for,by 介词后跟动名词。二、教学设计(teaching designs)

教学内容:课本(14-15)

这两页主要是介绍海洋的知识,教师可以先搜集一些关于海洋生物的图片,也可以让学生上网收集图片和照片。本课没有新的语言点,教材上安排了教学活动,主要是引起学生的兴趣,如班级里海洋知识的竞赛,教师也可以多收集一些类似的题目。另外要注意阅读技巧的培养。

说明:任务型教学活动多,学生有了更多的学习的自主空间,教师如何收放自如是关键,另外还要对学困生进行指导。竞赛是学生喜欢的学习方式,每班的竞赛方式可以根据教师平时教学组织的习惯来安排本节课的竞赛内容。

1   从杂志,网络上收集海洋生物的照片。问学生海洋生物的名字,可以用brain-storm

的形式。并用适当方式巩固海洋生物名称。

2   播放录音,让学生阅读文章。也可以在巩固海洋生物的基础上把p14-p15的阅读语

篇作为听力练习,让学生对文章内容先有个整体理解。

3   教师就文章内容设计提出一些问题,或是复述课文等活动,巩固复习阅读内容。

where do we find water? what can we find in the ocean? how can we get drinking water from sea water?

4  小组竞赛, 可以提高学生学习英语的兴趣,问题见:p15。 也可以收集其他多个问题与材料,进行全班检测与反馈。

海纳百川,有容乃大。上面就是山草香给大家整理的5篇Water教案,希望可以加深您对于写作water的相关认知。

step 1 greetings

step 2 revision and lead-in

ask someone to illustrate water properties.

step3: pre-reading

look at the titles in the text below. do not read the whole text. pick out the subject of each paragraph. use the structures below to make six questions related to the subjects.

what is/ are ________?

what does _________ look like?

what are different parts of ______?

what can ________ be compared to?

how does _______ work?

what are some examples of ________?

skim to find the words and phrases which describe the properties of water in the reading text.

scan to find out some basic facts about life in the oceans.

life on earth began in the oceans about three billion years ago;

99% of the living space on earth is in the oceans;

there are about five million (known) species in the oceans;

life in the oceans ranges from tiny plankton to giant whales.

t: yesterday you were required to ask more questions about water’s properties and find out the detailed information about water properties as well. so now let’s have a little quiz about the properties of water.

true of false questions:

1) water is a liquid at room temperature, and it has a relatively high freezing point.

2) the reason why water can dissolve most substances on earth is that water has high heat   capacity.

3) like all the other substances, water gets smaller (contract) when it freezes.

4) pure water has a higher freezing point and lighter than salt water.

5) the salinity of the earth’s oceans is about %.

6) when water freezes, its density increases.

7) other recourses such as oil, gas, gold etc is as precious as a drop of rain.

(tfftt ff)

step4. while-reading

as we all know, charles darwin is famous for his “the origin of species”。 (according to his theory of evolution)

qs: 1) was there any life on the earth billions of years ago?

2) if any, what was the original life like at that time?

3) where did it live?  -in the deep blue seas.

4) how does the world take its shape, which is quite different from what it used to be, especially those various organisms? -billions of years’ natural selection.

is said that 99% of the living space on earth is in the oceans.

qs: 1) what does this fact result in?    -marine life is incredibly rich and varied.

2) can you give some specific numbers or examples?

-there are about five million species in the oceans. they range from the tiniest plants all the way up to giants ( sharks and whales).

3) what does this fact imply? do you agree?

-water is an excellent medium for life.

4) why do you agree that water is an excellent medium for life? (based on common knowledge)

 water is a liquid at room temperature and has a relatively high freezing point;

 all living creatures need food to survive, but on many occasions the nutrients become available to living things only when they are dissolved by water.

we know that one of water’s properties is its dissolvability(溶解性).

qs: 1) do you know what gives water such a unique property?

-the chemical structure of water.

2) what does the water molecule look like?

-a water molecule consists of two hydrogen atoms and one oxygen atom. the two hydrogen atoms are bonded to one oxygen atom to form a 'v' shape. the two hydrogen atoms form a polar molecule, that is, one with a slightly positive end and one with a slightly negative end.

3) can you give some other examples which are also resulted from water’s unique chemical structure?

-plants can pull water up their roots via a capillary(毛细管) process;

-we can get a lot of nutrients by drinking soup.

that’s water’s another property-dissolvability.

4. since water is such a universal solvent, it can dissolve just about anything including many gases and solids. as a result, there is sea water.

qs: 1) do you know the salinity of the earth’s oceans? -about %.

2) what does it mean?

3) have you ever noticed such a phenomenon that in winter water in some containers or small rivers often freezes while that in seas not? can you explain it?

-the salinity of sea water can affect the freezing point of water. sea water has a lower a freezing point, so even when the temperature of sea water falls below 0℃, sea water is still liquid.

5. however, no matter whether it is sea water or pure water, “wood floats on water while iron sinks” always works. how do you explain that? what property of water is this?

-if a substance has a lower density than water does, it will float on water; otherwise, it will sink.

qs: 1) what is density? and what’s the density of pure water?

-density is the relationship between mass and volume and is measured in kilos per cubic meter (kg/m3). the density of water is 1,000kg/m3.

2) does it also go for the phenomenon that ice looks larger than water of equal mass?

-yes. water’s density decreases when it turns to ice, so its volume increases.

3) does all the water in the same river or ocean have equal density? tell your reasons.

—no. changes in salinity and temperature affect water’s density. cold water of high salinity usually is most dense and will tend to sink to the bottom of the ocean.

6. qs: 1) what do different densities in the ocean result in?

-dense water sinks and less dense water is pushed to the surface. thus water in the ocean is always moving.

2) what phenomena can this result help us explain? please give examples. (if necessary, give students some hints such as showing a picture etc.)

ocean motion helps move nutrients around and adds energy to the marine ecosystems.

different marine creatures live in different levels of the ocean. (because of the foods they need, sunshine etc.)

7. read following statement and think what conclusion you can draw? or what property does it refer to?

it is said that a man of 60kg loses about 1l water through breath and skin evaporation (皮肤蒸发) every day. in other words, 539kcal heat is released in these two ways. if so much heat were kept in human body, it would raise body temperature by 9℃. can you imagine the result?

-water has a relatively high heat capacity and can accommodate the climate automatically. it can absorb and release a lot of heat without big changes in its temperature, thus creating a stable environment.

8. here are some more familiar phenomena.

what property of water is each of them related to?

 the coastal areas are often neither too hot nor too cold. (water’s high heat capacity)

 ice floats on water. (density)

 when the sea water in a container is evaporated (蒸发), there will be some salt left. (dissolvability)

 irrigate in winter can help raise the soil temperature. (water’s high heat capacity)

 people swimming in the dead sea float; they can even read a paper while lying on their back in the water. (salinity and density)

step5 language points

…for

the company will provide food and drink for them.

2. have an opportunity to do something

i had no opportunity to discuss the problem with her yesterday.

variety of

he left for a variety of reasons.

there are a variety of patterns for you to choose from.

4. contribute to

his work has contributed to our understanding of this difficult subject.
