2. Recognize the necessity of garbage classification.

3. Enhance students' awareness of environmental protection.

Teaching Difficulties: How to make students take practical actions in their daily lives and actively participate in environmental protection.

Types of garbage

1, recyclables: mainly including waste paper, plastic, glass, metal, fabric and metal.

2, food waste: mainly including leftovers, bones, roots and leaves and other food waste. Biotechnology in situ treatment composting, each ton can produce 0.3 tons of organic fertilizer.

3. Hazardous waste: mainly includes waste batteries, waste fluorescent tubes, waste water silver thermometers, expired medicines and so on.

4. Other garbage: It refers to the garbage that can not be recycled for the time being.

Expanded Information:

Importance of garbage classification:

Conserve resources; no waste; make the city more beautiful .

1, to reduce the occupation of land: some of the substances in the domestic waste is not easy to degrade, so that the land is seriously eroded. Garbage classification, remove the can be recycled, not easy to degrade the material, reduce the amount of garbage up to 50% or more.

2, reduce environmental pollution: discarded batteries contain metal mercury, cadmium and other toxic substances, which can cause serious harm to humans; waste plastics in the soil will lead to crop yield reduction; abandoned waste plastics are accidentally eaten by animals, resulting in the death of the animal accidents happen from time to time. Therefore recycling can reduce the harm.

3, turn waste into treasure: China's annual use of plastic fast-food containers up to 4 billion, instant noodle bowls 500-700 million, waste plastic accounted for 4-7% of the domestic waste. 1 ton of waste plastic can be smelted back to 600 kilograms of diesel oil. Recycling 1,500 tons of waste paper can avoid cutting down forests used to produce 1,200 tons of paper. One ton of cans can be melted down to form one ton of very good aluminum blocks, which can reduce the mining of 20 tons of aluminum ore. 30%-40% of the production waste can be recycled and should be treasured as a small and profitable resource. We can also use cans to make pencil cases, both environmental protection, but also save resources.

2. Seek a classification of garbage "wet garbage" (food waste) class science lesson plans

Activity Objectives

Understand the significance of "classification of garbage"

Understand the classification of garbage

Be able to learn to classify garbage in daily life, and improve the ability to analyze, classify and compare

The ability to analyze, classify, and compare the garbage of different types of garbage is also important.

Focus and Difficulties

Focus: Knowing the simple classification of garbage and the meaning of "garbage classification"

Difficulties: Classifying and disposing of household garbage

Preparation for the Activity

Preparation for the Experience: Experiments on landfills and flower gardening with waste batteries have been done.

Material Preparation: making pulp tools, physical garbage and three garbage cans, video camera, paper and watercolor pencils

Activity Process

I. Introduce the subject

Question: What is garbage Why do sanitation workers have to sweep the garbage every day? How should we deal with the garbage that we picked up today? Use

1. Recognition of organic waste

① Question: What will be the use of leaves and other garbage after rotting (learning word: organic waste) What are also organic waste

② Watch video one, recall the changes in the leaves to understand the leaves and other garbage in the soil will rot, the garbage can be slowly turned into fertilizer, so that other plants grow better.

2. Recognize harmful, toxic waste

① watch video two, observe the changes in the plastic bag, and compare it with the changes in the leaves, and concluded that: the plastic bag will not rot, but only more and more pollution of the environment, resulting in white pollution, the animals accidentally ate will be dangerous, we call these garbage hazardous waste, so we should try to not use or use less of these things, to protect the environment.

② Question: We children know that there is a kind of garbage toxic, what is it who say the harm of waste batteries to us

③ Watch video three, understand the toxicity of waste batteries, know that batteries should be made special treatment.

④Question: What else is toxic and harmful garbage

3. Children observe the teacher doing pulp experiments to recognize recyclable garbage.

Question: How did the teacher do it? What did you find out

Conclusion: paper can be turned into pulp to make new paper, and paper can be recycled. （

Question: What are the other kinds of recyclable garbage

3. Classification of garbage

1. Ask the children to design the symbols of organic garbage, toxic and hazardous garbage, and recyclable garbage.

2. Ask the children to sort the garbage into three buckets.

Extension of the activity

Ask children to find out some information about garbage that can't be confirmed to be classified. Put the garbage cans in a corner of the activity room to help children continue to learn to classify garbage in their daily life.

Activity Evaluation

I. Design Intent

This lesson is the third activity in the theme activity - garbage, two experiments have been done before this, so this lesson is the summary of the whole theme activity, and the focus of the content of the refining. In this activity, it is mainly done by watching the video to recall the experimental process, results and doing experiments. This is mainly in consideration of the intuitive nature of young children to understand things, while taking into account the great interest of young children in watching videos and doing experiments, there have been several young children to ask me when I can look at the video of the experiments. Intuitive image of the video can attract the attention of young children, and can produce great attention to the content, at the same time, the operation of the experiment, practice is very strong, can let the children in the hands-on experience to obtain general knowledge about garbage. The focus of this lesson is on cognition and skills, mainly for children to understand the different characteristics of garbage, so that they can learn to classify garbage.

Second, the effect of analysis

Through this teaching activity, the first two experimental activities to make a summary of the children know more about the knowledge of the garbage, to understand the different methods of garbage disposal, and at the same time learned a simple classification. The use of video and experimental teaching methods made the classroom atmosphere very active, and the children's thinking was active and their speeches were bold, while the group teaching gave the children more opportunities to speak. The design of the garbage classification logo gives children the opportunity to actively participate and continue to think, and the teaching effect is better!

3. What are the benefits of garbage classification

The benefits of garbage classification

The benefits of garbage classification are obvious. After the garbage is sorted, it is sent to factories instead of landfills, which saves land, avoids pollution from landfills or incineration, and turns waste into treasure. For example, waste batteries are known as "miniature killers", as we all know that batteries in our lives contain heavy metals such as mercury or cadmium, and if these heavy metals are left in the ground, they can easily enter into the groundwater through the leaching of rainwater, which will cause serious persecution to the water resources and the land. However, waste batteries contain a variety of useful metal minerals, recycling value is very high. Because of the serious harm and special recycling value of waste batteries, many countries strictly prohibit them in the garbage and garbage mixing, Japan's community special yellow barrels, will be button batteries, etc. put separately. Again, such as leftovers lettuce, egg shells and peels, picking a class of kitchen garbage and other biological waste, but they can be used to make good organic fertilizer. Like the locust tree community in this big Nano dream biological waste treatment machine, can be biological waste drying, crushing, made of efficient organic fertilizer. Residents can use it to grow flowers and grass. Vegetables grown with them are safer and healthier than chemically fertilized food, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste, if they can be turned into organic fertilizer, not only to save land for landfills, but also to save vehicles and energy to transport them, but also to prevent them from breeding flies and bacteria.

So, there are many benefits of waste classification.

Introducing environmentally friendly trash cans

Generally speaking, the common environmentally friendly trash cans are divided into green, yellow, and red.

The green one is for recyclable garbage, recyclable garbage: paper, plastic, rubber, metal, glass, etc.

The yellow one is for recyclable garbage.

Yellow is non-recyclable garbage, non-recyclable garbage: mainly kitchen garbage, including fruit peels, vegetable

skins, leftovers, etc.

The red is for non-recyclable garbage.

Red put toxic and hazardous waste toxic and hazardous waste: batteries, fluorescent tubes, mercury thermometers,

paint buckets, medicines, cosmetics, etc..

The slogan about garbage classification

1. Garbage classification is beneficial, environmental protection depends on you and me 2. Please find a suitable home for garbage

3. If the garbage becomes treasure, classification and recycling is indispensable. 4. A classification of the heart of the people, the garbage can be turned into gold. 5. Garbage classification, the work of the hands
