MHI Thermal Systems Conducts Science Classes on Temperature Alteration at Two Elementary Schools in Kiyosu, Aichi
Every year MHI Group member Mitsubishi Heavy Industries Thermal Systems, Ltd., in line with MHI's CSR Action Guidelines and its commitments to "create a more harmonious society" and "inspire the future," dispatches young employees to teach science classes at elementary schools in Kiyosu, the city in Aichi Prefecture where its Biwajima Works is located. The classes are designed to have the children learn the enjoyment and wonders of science.
For the 2018 fiscal year, science classes were conducted for sixth graders at two local schools: Nishibiwajima Elementary School on November 21 and Kojo Elementary School on December 5. At both locations, the theme was learning how to alter the temperature of various materials. The employees who served as the day's teachers began by conducting various experiments through which the students learned how the temperature of various materials can be artificially changed. For example, they observed how compressing air causes its temperature to rise. Next, they saw how a bow drill can be used to generate frictional heat. The students confirmed the changes in temperature using a thermoviewer, a device whereby colors are shown on a screen to indicate the temperature of a material. In another experiment, they learned how temperature can be changed by dissolving an ordinary silica gel packet—of the kind commonly used as a desiccant—in water. Each group of children was able to sense warmth or coldness by directly touching the beaker. Last but not least, the children made orange sherbet by applying the principle that when salt is put into ice, the temperature becomes even lower.
The students listened attentively to the instructors' explanations and watched or took part in the experiments with great interest. Our hope is that classes such as this will spur young people's interest in science.
Going forward, MHI Group will continue to communicate closely with its local
communities, undertaking an array of activities to support the development of the next generation.
