1. First, summarize the contents of this section as a whole.

The earth is a planet in the solar system. The earth and the moon make up the earth-moon system. The sun, planets orbiting the sun, their satellites and various small celestial bodies make up the solar system. The sun is an ordinary star in the Milky Way, and the Milky Way is an ordinary galaxy in the universe. The rotation and revolution of the earth have formed periodic natural phenomena such as alternation of day and night and seasonal changes. Man's exploration of space is gradually uncovering the mystery of the universe. The study of the core concepts of this subject helps students to form interdisciplinary concepts such as matter and energy, system and model, stability and change.

2. Make clear requirements according to different standards.

Content requirements: three columns: learning cycle (1 ~ 2 grades, 3 ~ 4 grades, 5 ~ 6 grades, 7 ~ 9 grades), learning content and content requirements.

Academic requirements: divided into two columns: semester and academic requirements.

Teaching tips: divided into ① teaching strategy suggestions.

And suggestions for learning activities (observation-simulation experiment-production-project research).

Second, the most impressive

? What impressed me most was the teaching skills-suggestions for learning activities-simulation experiments and production. For example, the first lesson of Unit 3 is "Looking up at the sky", and Unit 3 involves exploring with the help of simulation experiments. "From the earth's point of view, why do the sun and the moon look so different?" .

In learning activity suggestions, based on the age characteristics of different students and the characteristics of corresponding knowledge points, learning activity suggestions have different emphasis angles, such as observation, simulation experiment, production, project learning, etc., which are suitable for different students' student styles and learning styles and facilitate students' better understanding and experience.

Thirdly, take the lesson of "Moon-Earth Satellite" in Unit 5 of "Three Stories" as an example.

? In this lesson, after I know the topographical features of the moon surface, I directly use the exercises in the student activity manual to guide the students to show the topographical features of the moon surface in a circle by drawing and labeling after watching the video and combining the front and back of the moon in the video and pictures.

After reading the new curriculum standard, I got a simple and interesting method to enhance the interaction between students and knowledge points-"make a model of the moon surface with ultra-light clay or clay, show the terrain features such as plains and craters, and understand the general situation of the moon surface". It is mentioned in the new curriculum standard that "designing students' favorite scientific activities, creating a pleasant teaching atmosphere, protecting students' curiosity and stimulating students' internal motivation to learn science" and "advocating diversified learning methods maintained by inquiry and practice, so that students can actively participate, use their brains, actively experience and experience the process of scientific inquiry and technical engineering practice".

The new curriculum standard not only keeps pace with the times, updates the educational concept, but also sorts out many key points for our teachers. It not only lets us know what we should know, but also teaches students what to learn, explore, summarize, reflect, apply and transfer, and promotes autonomous learning and cooperative learning. Students' learning is also teachers' learning, and so is teachers' learning.
