Scheduling Plan for the Third Grade of Science in Primary Schools 2019First semester of school year 1. Analysis of Learning Situation Compared with the previous third-grade students, this thirdgrade students are different, because they grow up together with the new science textbooks. 1. Levels of thinking and habits of behavior Through the first and second grade of science learning, students have a strong interest in science lessons, their desire for knowledge and participation in scientific activities has increased significantly, their ability significantly, of and observation their and description has developed of cooperation and ability sense of cooperation have also been fostered in a series of activities such as observation, recording, experiment and communication.Due to the limitation of age, students'thinking is still in the stage of image thinking, abstract generalization and language expression ability are still weak, and teachers' guidance and help are still very important.Teachers should also pay attention to the demonstration and guidance of observation and recording methods, and provide examples of language expression. Students have been able to control their emotions and behaviors initially, but there are still unstable phenomena, such as weak self-control, poor willpower, easy impulse when things happen, poor self-consciousness and persistence of activities, and often closely related to interest.In addition, they are energetic, active, curious and active. In the process of activities, they need to pay attention to the progress of students'observation and experience through continuous inspection, and promote students to better carry out observation and experience activities in the form they like. 2. Knowledge cohesion and learning basis Water Unit:Water is a very important substance on the earth and a typical representative of liquid.Students have accumulated a lot of cognitive experience about water in life, such as water can be used to clean things, water can dissolve some substances, bubbles can be seen in water and so on.This knowledge is interesting, directly related to the life situation, but also scattered.In teaching, teachers should transform students'perceptual knowledge of water into scientific concepts, and guide students to pay attention to and explore various issues related to water. Air unit:In the first grade textbook, the students have made a preliminary study of air in Lesson 7 of the "objects around us", but the research method is limited to the simple observation and description of air by sensory organs. Students have a certain perceptual understanding of the basic characteristics of air.Entering the third grade, students'inquiry methods and skills have developed to a great extent.Therefore, in the study of "air" unit, students are guided to use sensory organs and various assistant tools to conduct a more in-depth exploration of air as a substance. Weather Unit:The third grade students have a superficial understanding of the weather phenomenon, and have some intuitive feelings about the changes of the weather.Weather is closely related to our lives. Students notice that weather affects their lives. However, their understanding of the weather is still limited to sensory perception, or listening to the description of the weather by parents and weather forecast.Students also have a lot of questions about the weather, such as why thunder sometimes occurs on rainy days.Why is it sometimes cold and sometimes hot in a day?These are good learning opportunities. II. Textbook Analysis The first volume of science teaching content in the third grade consists of three units: "water", "air" and "w
