Principles of Science: Understanding the Physical Mechanisms Behind Sieving
Understanding the basic principles and process of screening is essential for the correct use of Tsinghua 81204 hand-held screens. Sieving is a common physical separation method that separates the mixture by particle size through sieves of different apertures. Different sizes of the screen can effectively divide the sample into multiple grades, so as to achieve accurate classification. By explaining these physical concepts, students and teachers can better use this tool for scientific inquiry.

Teaching Case: Successful Application in Science Classroom
Tsinghua 81204 handheld screens have been successfully used in science classes in many schools. For example, in a study of soil composition, the students used this handheld sieve to carefully classify the collected soil samples, resulting in accurate data. Through these specific teaching cases, we can see how Tsinghua 81204 Handheld Sieve helps students improve their experimental skills and scientific literacy.
User evaluation: a good helper recognized by teachers and students
Many users have given high praise after using Tsinghua 81204 handheld screen. A primary school teacher said, "This handheld screen is easy to operate and children love to use it. It not only improves classroom interaction, but also helps students better understand science." Another researcher said: "I often use this handheld screen in the laboratory.
