Laboratory Classes on the Wonders of Chemistry

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.
Taking into account the interests and opinions of the participants, the Laboratory Class topics are determined and developed by the Head Office and the Sodegaura Center. Relevant business divisions at the Head Office produce manuals on laboratory content and management and provide support for events organized at various Group sites in Japan and other countries. Additionally, leaflets that encourage children who have participated in laboratory experiments to take a more in-depth look at chemicals used at home have been published in response to external expert recommendations and these are being distributed to participants.
The program has also been registered as a group supporting the Saturday Educational Activities Program sponsored by the Ministry of Education, Culture, Sports, Science and Technology.
Donation of children's experiment kits
Although we had to refrain from holding our annual experiments and classes both at our sites and elsewhere due to the COVID-19 pandemic, experiment kits have been donated to local schools to offer children the experience of conducting an experiment.

Online Laboratory Classes
In fiscal 2021, we conducted a new online style of laboratory classes. The events were well received by the participants, who commented: “While various events were canceled due to COVID-19, I could enjoy it safely from home” and “It was an enlightening experiment.”
