Science Enlightenment: Opening the Window for Primary School Students to Explore the World

The introduction of scientific experiment tools at the primary school level is essential to cultivate students' spirit of exploration and preliminary scientific cognition. As a teaching instrument specially designed for children, Tsinghua 81204 handheld screen not only helps children establish an understanding of natural science, but also allows them to experience the charm of scientific research.

This handheld screen is designed with safety and ease of use in mind. It is made of high-strength stainless steel with smooth and rounded edges, ensuring that students will not feel discomfort or injury even if they use it for a long time. More importantly, under the guidance of teachers, students can independently complete various interesting screening experiments, such as sand filtration, grain grading and other tasks. Through these interactive learning processes, children gradually master the basic research methods and technical means.

Multi-purpose: to meet the needs of diverse teaching scenarios

Tsinghua 81204 handheld screen is equipped with three different specifications of the mesh surface, respectively, 0.5mm, 1mm and 2mm aperture, suitable for a wide range of sample processing work. Whether it is soil sample classification or seed size measurement, it can be easily dealt. For example, in a geography class, the teacher may use a smaller diameter (0.5mm) to demonstrate the difference in particulate matter in mud deposits; during a biology class, the teacher may prefer a larger size (2mm) to distinguish between different types of plant seeds.

This flexibility not only meets various needs inside and outside the classroom, but also provides convenient conditions for family education. Parents can organize small popular science activities at home to let their children participate and further stimulate their curiosity and thirst for knowledge. Not only that, the school can also include it in the list of regular experimental facilities to support more subject competitions and research projects.

High-quality materials and exquisite workmanship: ensure long-term stable performance

In order to ensure a durable and reliable running state, Tsinghua 81204 handheld screen is made of food-grade stainless steel. Compared with ordinary plastic products, this metal has higher corrosion resistance and mechanical strength, and is not easy to deform or break. And the surface after fine grinding and polishing treatment presents a bright luster texture, beautiful and generous at the same time also easy to clean up the residual stains.

In addition to high-quality raw materials, every product needs to go through strict quality control procedures before it can finally be sold on the market. From the assembly of parts to the final packaging and warehousing, all processes are strictly in accordance with national standards, and with the corresponding qualification documents for users to check and confirm. Such high standards and strict requirements make every buyer can rest assured to buy and rely on this practical teaching aid for a long time.

Easy Guide: Make every experiment a pleasant experience

In order to make it easier for parents and teachers to master the correct method of use, Tsinghua 81204 Hand Screen comes with a detailed manual. This includes a video tutorial on the operation steps of a combination of graphics and text, which is convenient for beginners to get started quickly. In addition, there are special warm tips for cleaning and maintenance, reminding everyone not to soak the whole device with water to prevent the internal components from being damaged by moisture. In addition, if there is any failure, contact the after-sales service department for technical support.

It is worth mentioning that the manual also contains some tips to help you better choose the grid model suitable for your project. For example, the average diameter range can be estimated in advance according to the characteristics of the object to be measured and then the specific parameter settings can be determined. Or in the case of uncertainty, a small amount of test comparison results will be done before the scale is expanded to officially start the measurement work. In short, with the help of the above information, even the first contact with such equipment can quickly get started and get satisfactory results.

Edutainment: Developing Children's Observation and Thinking Ability

In a typical class activity, we can see a group of fourth-grade students having a heated discussion around a few pots of small stones mixed together. "Look at this!" One of the girls excitedly pointed to a strange shape but slightly dull color pebble said, "I think it should be volcanic rock." Her words attracted the attention of the students around her, and everyone gathered around to look at the stone carefully.

Then the teacher issued an instruction: "Please divide these rocks into two groups according to your own ideas." As a result, the noisy classroom suddenly quieted down, and everyone seriously thought about how to distribute the babies in their hands. After a lot of effort, the first division was finally completed-on one side were large particles of hard, rough and angular texture; on the other side were relatively fine and smooth small gravel. This series of actions seems simple but greatly improves the children's concentration and logical reasoning level.

through such a lively, interesting and educational task arrangement, Tsinghua 81204 handheld screen not only teaches children how to distinguish the subtle differences between things, but more importantly, inspires them to learn systematic planning ideas when solving problems, which is very important for no matter what kind of industry they are engaged in in in the future
