Unit 5 Look into Science Lesson 30 Science Affects Us 教案 2025-2026学年冀教版（2012）英语九年级全册

Lesson 30: Science Affects Us
一、Teaching Objectives
Language Competence:
By the end of the lesson, students will be able to
Students can master new words and understand the letters about scientific experiments and the impact of science.
Students will be able to orally express at least two ways science affects daily life using sentence patterns like "Science affects us by making it possible to..." or "The development of ... has changed the way we..."
Cultural Awareness:
Students learn about the importance of science in daily life, develop an interest in scientific experiments and discoveries, and understand how science shapes our world.
Thinking Quality:
Students can analyze the letters, make connections between scientific knowledge and daily life, and think critically about the role of science in the future.
Learning Ability:
Students improve reading, writing, listening, and speaking skills through letter analysis, role-play, and group discussions.
二、Teaching Key and Difficult Points
Key Points:
1.Master new words: affects, developments, discoveries.
2.Understand the content of the letters and the scientific experiment described.
Difficult Points:
1.Explain the scientific experiment (air pressure) and the impact of science in simple English.
2.Discuss the future of scientific developments logically.
三、Teaching Methods
Task-based Language Teaching (TBLT)
Communicative Language Teaching (CLT)
Demonstration Method
Teaching Aids
PPT
五、Teaching Procedures
Step1. Warm-up
展示图片：快速展示几张与生活息息相关的科学发明图片（如：智能手机、Wi-Fi图标、疫苗、微波炉等）。
Greeting: "Good morning, class! What do these pictures have in common ” (引导学生说出“Science”或“Technology”)
追问：“Which one can you NOT live without Why ” 引出主题“Science Affects Us”。
Discussion:
What scientific inventions do you use every day
How do they affect your life
Step2. Presentation
New Words Teaching:
- Affects: "Weather affects our mood."
- Developments: "There are many new developments in technology."
development n ．发展→ develop v ．发展 developing adj ．发展中的→ developed adj ．发达的
- Discoveries: "Scientists have made great discoveries in space."
discovery n ．发现；发觉→ discoveries （复数）
※suggest v ．建议，提议；暗示→ suggest "建议，提议"，后常接名词、代词、动词的﹣ ing 形式或 that 从句，从句中用 should 表虚拟， should 可省略。→ suggestion n ．建议，为可数名词。 advice 也表示"意见，建议"，但为不可数名词。
Use the new words to complete sentences:
1. The new law ______ everyone in the country. (affects)
2. We should pay attention to the ______ of AI technology. (developments)
3. Scientific ______ can change the world. (discoveries)
- Let students read the words aloud and make their own sentences.
- Text Introduction: Introduce the two letters between Jenny and Wang Mei. Ask,
What do you think they are talking about in the letters
Step3. Reading
First Reading:
1.Read the letters quickly and match the main idea to each paragraph/letter.
Letter from Jenny: A. A fun science experiment about air pressure.
Letter from Wang Mei: B. The importance of science in our daily lives.
2.Ask students to read and fill in the blanks.
Science affects people ' s______ lives . Without the scientific developments of recent years , our lives would be very different . Can you imagine life without computers or______？ Scientific______ are making our lives better and better . DNA is really one of the most amazing things on the earth . Many people think it will______the world.
Second Reading:
活动1、Read the letters together as a class and answer the questions.
①What did Jenny describe in her e-mail
②Which of the air pressure is higher,pushing up on the cardboard or pushing down from inside the jar
③Why did Jenny feel "It was great fun"
④What does Wang Mei mean by "Without the scientific developments of recent years, our lives would be very different" Can you give an example
活动2、再次阅读文本，完成以下填空。
Jenny's Experiment:
1. Fill the jar with ________.
2. Cover the top with a piece of ________.
3. Hold the ________ on top and turn the jar ________.
4. Result: The water ________ fall.
5. Reason: The ________ pressure outside is ________ than the pressure of the water inside.
Third Reading (Intensive Reading & Language Focus):
任务： 全班跟读后，引导学生关注重点句型。
例句： "Without the scientific developments of recent years, our lives would be very different."
活动： 教师解释这个虚拟语气的句子结构（Without..., ... would...），并让学生进行仿写练习。例如："Without mobile phones, our communication would be less convenient."
例句：Scientific discoveries are making our lives better and better.
讲解：“make + object + adjective” 结构（使...变得...）。
操练：让学生用此句型造句。例如：“The Internet makes our life more convenient.”
Step4. Practice
教师提前准备好杯子、纸板和水，在课堂上真实演示“空气压力实验”。开展“教师演示，学生解说”的互动活动。
教师做实验动作，提问学生：“What am I doing now ” 引导学生说出关键步骤的英语表达，如：“You are filling the jar with water.”
在实验最关键的“倒转”时刻，可以先让学生预测：“What will happen when I turn it over Will the water fall ” 增加悬念和互动。
实验后，邀请1-2名学生上台，尝试用英语复述实验步骤和原理。教师从旁提供语言支持。
Step5. Production
Writing Task: Let students write a letter to a friend, introducing a scientific experiment they know or a scientific development that interests them, using the new words.
句型框架（写在PPT上）：
Dear [Friend's Name],
Today, I learned something interesting about science. I want to share [an experiment / a development] with you.
[Here, describe the experiment steps OR talk about the development].
I think it's amazing because... / This affects us by making it possible to...
What do you think Write back soon!
Best wishes,
[Your Name]
同伴互评：写完后，学生互相交换阅读，并基于一个简单标准给予反馈，如：“Can you understand the experiment/development he/she described ”
Step6. Summary and Homework
Summary: Recap the new words and the main content of the letters. Emphasize how science affects daily life.
Homework:
写一份实验报告
模板：Name of Experiment: ______ What I used: ______ Steps: 1. ... 2. ... What happened: ______ What I learned: ______
Find a simple scientific experiment and try it at home, then write a short report about it in English.
