Teaching plan of "turning waste into treasure" in large class scientific activities

Through activities, let children know how to protect the environment and cultivate their initial awareness of environmental protection. The following is the lesson plan of "turning waste into treasure" that I have compiled for you. Welcome to read, for reference only.

Teaching objectives:

1, children will tell the collected wastes and interesting things in the collection in words, and try to classify the wastes in various ways to broaden their thinking.

2. Let children have fun in the use of waste products, and develop their imagination, hands-on ability, problem-solving ability, innovation ability and communication ability in the production of "turning waste into treasure".

3. Let children know how to protect the environment through activities and cultivate their initial awareness of environmental protection.

Teaching preparation:

1. "waste questionnaire * * * filled out by children and parents.

2. The scene of "Wonderful Store"; Pictures and related gifts of elephants, monkeys, kittens, pigs, foxes and chickens, toys made of various wastes, etc.

3. All kinds of rubbish collected by children.

Teaching process:

1. Take "Wonderful Store" as the story introduction activity.

(1) Children, when you eat peaches, watermelons and grapes, what should you do with peach stones, watermelon skins and grape seeds? An uncle elephant may have dried up. He turned these rubbish into gifts for animal friends. Do you want to know what the gift is? Please listen to the story of "Wonderful Store".

(2) Question: What waste did the small animals make as gifts? What is the use of Uncle Elephant's "wonderful shop"? Use waste, turn waste into treasure, protect the environment and prevent pollution. )

2. Children talk about the collected waste and collect interesting things.

(1) There are many wastes in our life every day. A few days ago, we also made a survey on "collecting waste products". Please tell the children next to you what waste products you collected, and what interesting things happened during the collection process can also be said.

(2) Ask 2-3 children to introduce the questionnaire and talk about the interesting things that happened in the collection.

3. Encourage children to try to classify waste products in various ways.

(1) You see, these cartons are all scraps picked up by children from home. So many put together at sixes and sevens. Is there any good way to keep these wastes in order?

The children said: if the same items are put together. Such as a pile of bottles, a pile of boxes and so on. The children put them in the box by hand.

Scrap What waste products do you think have not been properly placed? Please check the placement of 1-2 children.

(2) Besides, can you think of any other better points? Teachers encourage children to come up with different ways of division, such as: box division (candy box, toothpaste box, shoe box); Bottles (shampoo bottles, medicine bottles, beverage bottles), etc.

(3) Teachers should seize the opportunity of education and guide children to classify according to waste materials. For example, children say: You can put things made of paper together. Find out what else is made of paper. Let's take a look at what materials are used in other garbage. Children say metal, glass, plastic, etc. And find out what the related waste products are? Discuss where to put it separately.

The children sorted the waste products according to the materials again. Teachers and students * * * check the classification and ask children to help send unsuitable waste materials to such waste materials.

4. Talk about the utilization of waste products.

(1) Question: How to use the collected waste? Some waste products can "turn waste into treasure, protect the environment and prevent pollution; Some waste products can be recycled to save resources. )

(2) The role of waste products is really great. Small animals in the forest also make many interesting gifts from waste like uncle elephant. Let's go and see what toys are in the Wonder Store. See what materials they made and what gifts they made.

5. Teaching expansion:

(1) Children, do you want to use your hands and brains to turn these wastes we collected into various useful things and send them to Uncle Elephant's shop?

(2) Children's manual work, teachers' itinerant guidance, children's mutual exchange of production experience, and negotiation to solve problems encountered.

(3) Appreciate each other's works, show children's works on the KT board, communicate with each other, and experience the fun of making and the joy of success.
