Teaching Objectives:
1.Learn about cups made of different materials and learn about environmental protection.
2.Arouse children's desire and encourage children to operate.
3.Develop children's imagination and creativity.
Teaching difficulties:
Get to know cups made of different materials and infiltrate environmental protection knowledge.
Teaching preparation: all kinds of cups, colored dough, tray teaching.
Rationale:
Children's science should start from the things around them, guide children to pay attention to the common things in the surrounding life and environment, and find the interesting and wonderful in them, which is beneficial to maintaining children's curiosity. The "Outline" points out that scientific activities should use a variety of senses, use hands and brains, and ask questions, feel things from life and games, and have a preliminary awareness of environmental protection. Therefore, teachers should always pay attention to children's behavior, be good at discovering the hidden educational value of things they are interested in, seize the opportunity of education, provide rich operable materials for children's activities, and create a relaxed environment. The cup is a familiar item in children's daily life, although children usually know the cup and use it more frequently, but most children do not understand the external characteristics and functions of the cup. In order to let children use their multiple senses to understand cups made of different materials and establish a good sense of environmental protection, I designed this activity.
Teaching process:
1. Appreciate the cup master showing the cup: what is it? What do they look like? What is it made of?
2. Guide children to observe freely, and initially perceive different cups by looking and talkingTeacher: Today, the teacher has brought a lot of cups for babies, take a look at which one you like the most (remove the cover, children fully observe) and ask you to talk softly to your good friend (child communication) 2Ask individual toddlers to tell us which cup you like best.
By comparing and understanding the cups, and classifying the cups, including appearance, pattern, size, texture, height, etc., show two different cups many times, and let the children compare what are the differences between them? Including appearance, pattern, size, texture, height and other children to classify the cup. (Teachers make itinerant guides, individual questions: How do you divide them?) (from Teacher Qu's lesson plan) summary: These cups are different, some cups are tall, some cups are short; Some cups have handles, while others don't; Some cups are green, some are red; Some cups are plastic, others are glass; Some cups are ceramic, some cups are enamelled glasses, porcelain cups are easy to break, and enamel cups are easy to fall off, so we have to take them gently and put them gently.
3. Introduce several special cups, recognize disposable paper cups and disposable plastic cups (show disposable paper cups and plastic cups).
1.Question: What are the benefits of disposable cups Convenient and hygienic, do you think it is better to use paper cups or plastic cups? Analyze the impact of paper cups and plastic cups on the environment.
2.Teacher: Isn't it hygienic to use all disposable cups?
Guide children to say that plastic cups will cause secondary pollution, while paper cups can be reused. Let children know how to use items that are good for the human environment and learn to protect the environment. Ask the children to see that there is a long line under this cup, and there is a jack, what kind of cup is this?
3.The teacher demonstrates boiling water with an electric cup.
4.Get to know the thermos cup. (Show the glass thermos cup and stainless steel thermos cup in turn, let the children observe) Introduction: One is the glass thermos cup, which is composed of double-layer glass, and the middle of the double-layer glass is vacuum, and the hot water is not easy to get cold. There is also a stainless steel thermos cup, which is a cup made of stainless steel and a vacuum layer, with a lid on the top, and the vacuum insulation layer can delay the heat dissipation of the water contained in it to achieve the purpose of heat preservation.
Summary: The world of cups is amazing, there are so many cute and beautiful cups.
4. Imagine and make cupsToday, please ask the children to be smart and capable designers and design your favorite cups. Toddlers make cups with their hands.
1.Ask individual children to introduce their cups. (What is the use of how to do it, what shape, color?) )
2.Exhibit cups made by toddlers. Teaching EvaluationThis activity is mainly to let children know about cups of different materials on the basis of observation, exploration and communication, and understand relevant environmental protection knowledge.
