Laboratory Classes on the Wonders of Chemistry

Copyright©2006-2020 Mitsui Chemicals, Inc. All Rights Reserved.

Point three in the Mitsui Chemicals Group Social Activities Policy is, “Do its bit to nurture future generations, on whose shoulders the future rests.” In order to further this goal on a global basis, the Mitsui Chemicals Group launched the Laboratory Classes on the Wonders of Chemistry program.
Since 2006, we have organized various types of classes, from off-site classes, whereby members of staff from each of our sites go out to local schools, summer vacation events and festivals, to those held during tours round our works and research centers. Approximately 5,000 children took part in classes over the course of fiscal 2019.

Taking into account the interests and opinions of the participants, the Laboratory Class themes are determined and developed by the Head Office and the Sodegaura Center. The Head Office also provides support for the creation and maintenance of manuals allowing development of the program at domestic and overseas group locations. Accepting a suggestion from an external expert, we created a leaflet that children could take home to read and learn more about chemistry. In fiscal 2020, we plan to ask participants to complete a questionnaire after the class to help improve the contents of experiments to meet each school’s specific needs and challenges.

In recognition of these activities, we received the Catalysis Society of Japan’s 2015 Award for Education and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) Award for Companies Promoting Experience-based Learning Activities for the Youth (Judge’s Commendation) in the large corporation category for 2015. In addition, we registered with the Ministry of Education, Culture, Sports, Science and Technology Support Group for Saturday Educational Activities Program and are working to spread education to even more children.

Experiment Workshop in Longmiao Hope Primary School in China

To celebrate the 10th anniversary of its establishment in 2010, Mitsui Chemicals (China) Co., Ltd. donated funds to rebuild the old buildings of a primary school in the rural area of Anhui, China, as a part of the company’s social contribution project. The school renamed itself as Longmiao Hope Primary School and we have continued to provide support since then. In fiscal 2018, we donated funds to install flush Toilets and attendedthe completion ceremony held on October 10. Our employees also held an experimental workshop to create urethane foam and balloon slime. The children were totally engrossed in the experiment, which turns liquid into a solid material, fully enjoying the wonders of science! We will continue to support the local community through exchanges with Longmiao Hope Project Primary School.

Participating in a Summer Holidays Science Show for Children

On August 3 and 4, 2019, we participated and presented shows in Dream Chemistry 21– Summer Holidays Science Show for Children*, held in the Science Museum in Tokyo. At our booth, we demonstrated an experiment using a film made from our product, ABSORTOMER™. Some 240 primary school children learned about the features of this plastic and were amazed to see how the film expanded or shrank when it was soaked in hot or cold water.

*Dream Chemistry 21 – Summer Holidays Science Show for Children:
Hands-on scientific workshops for primary school pupils and their parents held during the summer holidays every year. These workshops are sponsored by the Dream Chemistry 21 Committee, comprising the Chemical Society of Japan; Society of Chemical Engineers, Japan; Japan Association for Chemical Innovation; and the Japan Chemical Industry Association. The workshops, developed by leading chemical companies in Japan, are specifically designed to entertain and educate children.
