How to record the science cloud in the third grade of primary school

The records of scientific clouds in the third grade of primary school are as follows:

1, cloud cover is closely related to rainfall, and the increase of cloud cover indicates the arrival of precipitation. Here, guide students to observe and describe the cloud cover in the sky, and guess the relationship between cloud cover and rainfall with the method just learned.

2. Clouds are closely related to rainfall and snowfall, and observation of clouds is an important part of weather observation. The main purpose here is to guide students to know what cloud cover is, and to teach an observation method to estimate cloud cover according to the degree to which clouds cover the sky.

3. The rain gauge is a special instrument for measuring rainfall. This paper introduces a simple method of making rain gauge, and deepens students' understanding of the principle of rainfall measurement by guiding students to complete the process of making rain gauge.

4. Rainfall is a common natural phenomenon in daily life. However, the more common the phenomenon, the easier it is to be ignored. By discussing the influence of rainfall on human production and life, guide students to realize the importance of rainfall. Not only the negative effects are discussed here, but also the positive effects of rainfall are involved to help students establish a comprehensive and complete understanding.
