حل درس Photosynthesis لغة إنجليزية الصف التاسع


Lesson 3

Learning obiectives

Reading : To develop learners' ability. to read about how plants help the balance of carbon dioxide and oxygen in the air

Vocabulary

Oxygen

Carbon Dioxide

Respiration

Breathe

Photosynthesis

Energy

Learnin the lesson. learners will be to

• use a text to complete an equation

 describe the function of different part of a plant

 use scientific language to complete a text about photosynthesis

Learning objectives

Reading

To develop learners' ability to read about how plants help the balance of cartxn dioxide and oxygen in the air

 

Reading

Read about how plants help the balance of carbon dioxide and oxygen in the air. Use the information to complete the equation

Photosynthesis is how plants make their own food to get energy. This is how they do it

Plants take in carbon dioxide from the air through their leaves. They take up water from the ground through their roots. Energy from sunlight works together with the carbon dioxide and water to The plant uses the sugar for food and the oxygen is released into the air through the leaves

energy fron is released

sugar is prcxiuced

oxygen Of the plant

water + carbon dioxide

Discussion

Why are the following important for plants

I) Leaves

Leaves are important for plants because they take in carbon dioxide and release oxy en through the

Roots

The plant needs roots to take up water from the ground. Reading: To develop

3) Sunlight

Sunlight is needed for photosynthesis to take place

4) sugar (glucose)

Sugar is needed for energy

Learning

learners' ability to read about how plants help the balance of carbon dioxide and oxygen in the air

 

Lesson 4

Listening : To develop leamers ability to listen to a discussion and complete a worksheet based on it

 use reading comprehension skills in order to order a text

 listen for scientific  information

 use scientific language to complete a text about photosynthesis

 write quiz questions on a given topic

Carbon dioxide

Leaf

Photosynthesis

 

Speaking

Imagine you are explaining photosynthesis to a classmate. What would you say

Use some present passive sentences

First Of all, plants

Then, they

This

Oxygen is

Sugar and oxygen are

- Object + 2- v. to ( is- am — are simple present ) 3- main Verb

Present passive

Use of English: Present passive In scientific and technical writing, the passive is often used. This is because we focus on the action, not the person or the thing that does the action

Oxygen is released into the air through the leaves

We store information in the computer

Subject verb object

information is stored in the computer

object   verb to be    main verb P.P

 

Listening

Listen to Alia and Zahra doing their Science homework. Help them to complete the worksheet their teacher has given them

Photosynthesis and aerobic respiration

When there is bright light

There is more photosynthesis than reiration. carbon dioxide taken

. More oxygen than carbon dioxide and oxygen

When there is dim light

There is equal and respiration. No gases

In other words, oxygen and carbon dioxide When it's dark

There is respiration, but there is no photosynthesis. Oxygen and carbon dioxide Video ………... More carbon dioxide than oxygen

2. S guenout S. aren't taken in

8. is given out

3. 6. gwen out

9. is produced

4. are given out 7. in

Workbook

Ac 5: write the sentences in the correct places

Carbon dioxide is taken in and oxygen is given out

 Neither oxygen nor carbon dioxide are given out or taken in The plant produces more carbon dioxide than oxygen

 More oxygen than carbon dioxide is produced

 There is no photosynthesis

When it's dark, oxygen is taken in and carbon dioxide is given out

 When there is bright light, photosynthesis happens

When there is dim light, both photosynthesis and respiration take place
