"Where do these things come from?" Where does a good life come from PPT (Lesson 1)

Part One: Conversation Introduction

Students, what items do we use in our daily lives? Which of these items are agricultural products and which are industrial products?

We have explored the production sources of agricultural products in the previous lesson, so what are the sources of these industrial products? Are they grown like agricultural products? Today, we will explore this issue together.

Where do these things come from PPT, part two: exploration of new knowledge

Activity 1: “Exploring the Secret” of the Origin of the Object

(1) Take a look and fill it out.

1. Observe and see what items are used in your family life. Which ones come from industrial production?

2. Classify items from industrial production according to use and wear.

(1) Students communicate in groups and complete the form.

(2) Exchange and report with the whole class.

Our lives are inseparable from various daily necessities. Many daily necessities are provided by industrial production. Industry is closely connected with our lives. So how are the industrial products that are closely connected to our lives made? How many people in the industry are required to make an industrial product? With these questions, let’s explore how teddy bears are produced.

(2) Visiting activities and talk about them.

1. Visiting activities.

On my birthday, my mother gave me a cute toy bear. Looking at the cute little bear, I really want to know his origin. Out of curiosity, I walked into the factory that produces toy bears and conducted a visit.

①In the product research and development department of the toy manufacturing factory, designers focus on designing various cute bear styles.

②In the material workshop, there are many raw materials for making bears, including velvet, floral cloth...

③In the production workshop, I saw a busy scene, with workers immersed in operating sewing machines.

④In the decoration workshop, workers sewed eyes on the bear and tied a bow, and the cute toy bear was born!

⑤In the inspection and packaging workshop, technicians are strictly inspecting each toy bear and packaging it only after passing the inspection.

⑥The packaged bears are transported to the store and sit proudly on the shelves, waiting for people to buy them.

2. Let’s talk about it: What steps does the production of a toy bear go through?

Design - material selection - sewing - decoration - inspection, packaging - sale

3. Explore the production process of ice cream:

Ingredients - mixing - sterilization - cooling - homogenization - aging - freezing - filling - packaging - hardening - inspection - finished product - sale

Free visit: Choose an item you like and start exploring its origins.

We understand that industry has penetrated into every corner of our lives, and industry and our lives have been closely linked. Every industrial product is manufactured by people from countless industries. We should cherish the fruits of everyone's labor.

Activity 2: The comfort and convenience they bring

1. Contrast.

Wash clothes by hand→wash clothes in washing machine

Walk upstairs → take the elevator upstairs

Use a fan to enjoy the coolness → enjoy the coolness with the air conditioner

With the washing machine, not only does it save manpower, but you no longer have to worry about the cold when doing laundry in winter; with the elevator, you no longer feel tired climbing stairs; with the air conditioner, it is no longer hot in summer and no longer cold in winter. Industry brings comfort and convenience to our lives.

A little research:

Ask your family members, which items they used when they were children are no longer produced? Which items did not exist in the past but are available now, and what comfort and convenience have they brought to our lives?

(1) Students communicate using materials collected before class.

(2) Students communicate and report to the whole class.

Expansion: For example: In the past, only firewood could be burned for cooking in rural areas, but now biogas and natural gas are installed in rural areas, which not only saves manpower, but is also very environmentally friendly; in the past, people wore shoes made of wood or cloth, which were not warm to wear. , and it is not easy to take care of. Now people wear leather shoes, which are both warm and easy to take care of. In the past, people lived in thatched houses or mud houses, but now people live in reinforced concrete high-rise buildings, and they are no longer afraid of wind. The sun is blowing...

Think about it: Starting from people’s daily needs, what other products can we improve and invent?

(1) Students design their ideas:

(2) Students communicate their own designs within the group.

(3) Each group invites a student to communicate and report to the whole class.
