An awards ceremony for the 'Rain Gauge Design Competition', which ran earlier this year, was held today (September 9) at Theatre P3 of the Chong Yuet Ming Science Buildings, University of Hong Kong.
The Hong Kong Observatory organised the competition jointly with the Department of Computer Science and the Department of Electrical & Electronic Engineering of the Faculty of Engineering, the University of Hong Kong. It was the first of its kind in Hong Kong.
The objective of the competition was to enhance the knowledge of and interest in information technology and meteorological instrumentation among primary and secondary school students in Hong Kong. The theme was chosen in view of the human reliance on water as an essential element of life. At any time and anywhere in the world, people have always been curious about the natural phenomenon of rain. The measurement of rainfall alone has become a kind of special knowledge.
To enhance participants' understanding of the various methods of rain measurement, the Hong Kong University and the Hong Kong Observatory organised a series of talks, workshops and visits earlier in the year to familiarise the students with the topic and enable them to be more creative and accurate when designing their rain gauges.
Altogether more than 110 students from 16 schools ranging from Primary 5 to Form 7 took part in the competition. More than 20 entries take on various designs and shapes, ranging from simple containers to very unique designs as well as automatic recorders. They amply demonstrate the students' ability and creative ideas in their application of meteorological measurement and information technology.
In the awards ceremony today (September 9), Prof TS Ng, Dean of Engineering, the University of Hong Kong, praised students for their engineering creativity in the design and implementation of a wide variety of rain gauges. The products have been carefully calibrated, their hardware and software beautifully engineered, and their work elegantly presented. All these show that they are the engineers and scientists of our next generation.
Mr CY Lam, Director of the Hong Kong Observatory, remarked on the occasion "I greatly appreciate the effort and ideas of the students. Measuring rain looks like a simple task, however it actually involves subtle planning. The students would be able to learn a lot from the competition including the rigour required in science, the need to learn from failures in order to succeed and the task-sharing among schoolmates. All these are invaluable experiences. I highly encourage the students to treat this participation as a starting point and be prepared for more explorations and innovations in the future."
The Champion of the Junior category is a team of primary five students from C.& M.A. Chui Chak Lam Memorial School. Mr Cheng Ka Lok, the supervisor of the team, was both surprised and delighted at the team's performance. He said that the team members were all from the same class. They worked closely together for the competition. The students collected rainwater with their rain gauge and measured the rainfall everyday. The calculations involved had not been taught during class and yet Mr Cheng was pleased that the students were able to apply their knowledge to real-life situations. Dr Yip Chi Lap, one of the judges from the Department of Computer Science, the University of Hong Kong, indicated that the team was the first to submit their product. What makes it really commendable is that they were able to provide one and a half month's worth of test data.
The Champion team of the Senior category is from Tin Shui Wai Government Secondary School. The team has only two members, the smallest among the groups. Their supervisor, Mr Tse Ming Wai, said that the students were aware of only a few designs for automatic rain gauges at the beginning of the project. However, after research on the web, they found that there existed quite a number of ways to make rain gauges. Hence, the students decided to design a rain gauge that would incorporate the advantages of different types of rain gauges. Mr Tse commended his students for their tenacity. In the few months after their public examinations, the team worked every day in the laboratory to test and improve the different parts of their design. As Form 7 students, they had a higher expectation of themselves in view of their better understanding of science. They spent more than a month carrying out experiments to find out the relationship between the water drop size and the water level inside the rain collector. This way they improved their design until satisfactory results were obtained. He hoped that the rain gauge could be put into practical use.
