Science experiment, making popcorn, teaching plan, small class reflectionThe following is a reflection on the lesson plan of making popcorn for the small class science experiment:
** 1. Achievement of teaching objectives **
1. ** Knowledge target **
- From the teaching plan, it was designed to let the children understand the basic characteristics of corn and sense that corn could turn into popcorn when heated in the microwave oven. In actual teaching, if the child could accurately tell the color, shape, touch, and other characteristics of the corn, and could clearly compare the difference between corn and popcorn, such as corn being small and hard, popcorn being fluffy and soft, then it meant that the knowledge goal was relatively successful.
2. ** Skill Target **
- During the activity, the children trained their observational skills by observing the changes of the corn grains in the microwave oven, such as seeing the changes in the bag, smelling the smell, hearing the sound, etc. If the child could actively participate in these observation sessions and accurately describe what he saw, smelled, and heard, then he would have a better performance in achieving the skill goal. At the same time, if the children could imitate the process of turning corn into popcorn in the music game, it also showed that they had a certain understanding and performance ability of this change process.
3. ** Emotional goal **
- If the child showed a strong interest in the corn and popcorn throughout the activity, actively participated in the production process, and showed positive emotions such as excitement and curiosity when seeing the corn turn into popcorn, then the emotional goal was well achieved.
** 2. Teaching process **
1. ** Introduction Stage **
- The teacher showed the PowerPoint, showed the corn doll, and introduced the corn. This method of introduction could attract the attention of young children and stimulate their curiosity. If the child could be quickly attracted and actively respond to the teacher's questions, such as correctly answering that the baby on the corn was corn, then the introduction was effective.
2. ** Observation segment **
- Let the children personally take the corn to observe and understand the characteristics of the corn by looking, pinching, touching, etc. This segment helped the child to intuitively feel the characteristics of the corn. However, the possible problem is that young children may not be able to concentrate because of their young age, or they may not be accurate enough in expressing their feelings. Teachers needed to give more guidance and patience in this part to ensure that every child could participate in the observation.
3. ** Production (Heat the corn into popcorn)**
- The core process was to heat the corn into popcorn in the microwave. In this process, there were some safety issues that needed to be paid attention to, such as the safety of the microwave oven. The lesson plan emphasized that it was necessary to carry out it with the help of parents. At the same time, during the teaching process, if the child was too curious about the change process of the corn in the microwave oven and wanted to get close to observe, the teacher needed to stop the child in time and guide the child to observe from a safe distance.
- In the process of observing the changes in the corn, it was very good to let the children see, smell, listen and other senses participate. However, the possible shortcoming was that children might overlook some details because of excitement. Teachers needed to ask questions and guide them at the right time to ensure that children could fully perceive this change process.
4. ** Game segment **
- The music game "Turn Corns into Popcorn" allowed children to further experience the process of turning corn into popcorn in a relaxed and happy atmosphere. However, there may be chaos during the game. Teachers need to formulate the rules of the game in advance and maintain order in time during the game to ensure that every child can gain something from the game.
** 3. Teaching materials **
1. ** Ppowerpoint **
- The PowerPoint played a very good supporting role in the teaching process. It could directly display the content of corn dolls and corn seeds. However, the content of the PowerPoint presentation had to be designed in accordance with the cognitive level of the children in the small class. The picture had to be simple, colorful, and vivid. If the pictures in the PowerPoint were too complicated or there were too many words, it might affect the child's understanding and interest.
2. ** Corns, microwave oven and other materials **
- The corn was a material material that could be directly touched and observed by children. This was very good. However, when using the microwave oven, it was necessary to ensure its safety and take into account possible emergencies, such as the failure of the microwave oven and the over-heating of the corn.
** 4. Individual differences in children **
1. In the entire teaching process, the individual differences of small class children may be more obvious. Some children may already have a certain understanding of corn and popcorn, and their participation will be higher, while some children may be more timid or less accepting of new things. Teachers needed to pay attention to these individual differences and give different levels of guidance and encouragement to different children in the activities to ensure that every child could develop in the activities. For example, for a timid child who did not dare to participate, the teacher could hold his hand to operate together to enhance his confidence.
