Entering the Precision Instrument Laboratory of Tsinghua University: Exploring the back of efficient teaching aids

Tsinghua 81204 handheld sieve is the crystallization of many years of scientific research achievements of Tsinghua University, which embodies the painstaking efforts and wisdom of scientists. This device does not appear by accident, but an innovative product launched after countless trials and improvements. With the development of science and technology, the education sector has begun to attach importance to the introduction of cutting-edge research results into classroom teaching, especially for the cultivation of the next generation of innovative talents.

Today, Tsinghua 81204 handheld screen has become an integral part of many elementary school science curriculum. Its existence not only changes the traditional teaching mode, but also greatly promotes the students' active learning interest. By experiencing the convenience and accuracy of this advanced tool, children can deepen their understanding of knowledge in practice and stimulate unlimited potential.

Triple Specifications, One Grip and Sieve: Meet Diversified Sample Processing Needs

In order to allow every user to find the most suitable screening method, Tsinghua 81204 handheld screen is equipped with three different sizes of mesh-coarse, medium and fine. Each specification has a specific design purpose and is suitable for a specific type of task. For example, the coarse screen is suitable for the separation of larger particulate matter; the medium screen is the ideal choice for more delicate materials such as soil; and the fine screen can achieve the effective filtration of very small particles.

In a simulated ecosystem research project, the teacher led the students to collect some plant seeds and bring them back to the classroom for observation. At this time, if you want to accurately distinguish the various sand and gravel blocks of different sizes, then you can completely rely on this multi-level sorting equipment to complete the task! This will not only save a lot of time and cost, but also give everyone a deeper understanding of the mysteries of nature.

Ingenious portable design: inquiry learning anytime, anywhere

Considering that students often need to go out for various practical activities, the designers cleverly changed the originally bulky traditional fixtures into a portable handheld version. The new lightweight body is matched with the humanized handle design that conforms to the ergonomic principle, which makes it easy to cope with complex environmental changes both indoors and outdoors. And because of its small size, even children can hold it with one hand.

Once, during an off-campus expedition, several students encountered a soil sample in an unknown area. Just when everyone was confused, someone suddenly thought of taking out a small assistant to help solve the problem. I saw him skillfully adjust the angle and then gently shake a few times, instantly removing all impurities in the soil layer. This experience made them understand that science is not far away, as long as they are good at using the things around them, they can find more fun.

Intuitive and easy-to-understand operation interface: stimulate students' independent innovation ability

In order to make it easier for students to understand and master the correct method of use, Tsinghua 81204 handheld screen adopts a simple and clear sign system with instructions. Each part is clearly marked, including but not limited to the location of functional components such as the feed inlet, vibration button and empty switch. Such a setting can not only reduce the confusion of first-time contacts, but more importantly, it can inspire them to try new things.

When faced with a new challenge or problem, we often choose to first imitate what others have already done. However, in the process of gradually accumulating experience and skills will gradually form their own way of thinking. This is why we need to give children enough time to try and not rush to tell the answer.

Durable and reliable product performance: ensure the success rate of every experiment

One of the key reasons why Tsinghua 81204 handheld screen can be widely praised in the market is its excellent physical properties. The whole set of appliances are forged from high-strength stainless steel, with excellent rust and corrosion resistance. Even long-term exposure to humid air is not easy to damage the deformation. In addition, the manufacturer has carried out strict testing and certification procedures for its internal structure, so as to ensure that each one has reached the highest quality standards before leaving the factory.

At a large-scale popular science exhibition organized by the school, many exhibitors brought their latest research and development works for visitors to try out. However, at the end of the last day, it was discovered that only a few of the exhibits on the booths were still intact. Among them is our "star player", because it has always maintained a stable operating state and has never failed. This proves once again that good products really stand the test.

Promoting Interaction: Building a Better Home-School Cooperation Platform

In addition to playing a role in the school, Tsinghua 81204 handheld screen can also become a beautiful scenery in family life. Many parents have reported that since the family has acquired such a small
