Laboratory Classes on the Wonders of Chemistry

Wonders of Chemistry

The Laboratory Classes on the Wonders of Chemistry is one of the activities that the Mitsui Chemicals Group is promoting globally to contribute to society using chemical technology, to coexist with local communities, and to develop the next generation of human resources, in accordance with the Social Activities Policy.

Launched in 2006 with the desire to show children the fun and potential of chemistry and to spark their interest in pursuing science, 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 around our works and laboratories. In fiscal 2023, we conducted 23 delivery laboratory classes, with approximately 2,400 children participating.

The experimental topics were developed primarily by the members of VISION HUB™ SODEGAURA, incorporating feedback from participants. Each of our Group locations adapts these experiments, standardizing the content and operations into manuals. The Head Office department in charge provides support for these events and facilitates the sharing of implementation statuses across all locations, both in Japan and internationally. 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, and these are being distributed to participants.

Delivery Laboratory Classes

In fiscal 2023, we held delivery laboratory classes for the Wonders of Chemistry.

Participated in “Dream Chemistry-21” Summer Vacation Children’s Chemistry Experiment Show 2023 Sponsored by the Japan Chemical Industry Association

Under infection control measures and a reservation system with limited numbers, we joined 14 other chemical manufacturers and six organizations over August 5 and 6 to provide approximately 128 children* with the chance to experience the fun and wonder of chemistry. We participated as a joint effort among four of our bases: the Head Office, Ichihara Works, Mobara Branch Factory, and Sodegaura Center. Over the two days, a total of 66 employees served as staff, helping children create air fresheners using nonwoven fabric (oil blotters) to take home as souvenirs.

Participated in the “Have Fun while Learning About SDGs in KOBE” Delivery Class

On March 26, 2024, our Osaka branch participated in “Have Fun while Learning About SDGs in KOBE,” a children’s fun-filled, experiential event focused on the SDGs, hosted by Amita Holdings. We were invited by the city of Kobe as a company engaged in SDG activities like resource recycling.

At our booth, the topic was “Sorting Plastics,” where children observed whether four types of plastic fragments would float or sink in water, salt water, and disinfectant. Ultimately, they learned through quizzes and experiments to determine what those plastic fragments were.

The event was held at Futaba Gakusha in Kobe’s Nagata Ward, where the Recycle Eco Bench—produced from mechanical recycling of plastics collected by our company in 2022—was installed*.

Business site tour by Hozo Hut children - Chemistry and Wonder Laboratory Classes in China

In August 2022, Mitsui Chemicals (China) Management Company Limited (MCCN) organized a tour of MCCN's Technical Center as an out-of-school learning experience for the children of the “Hozo Hut (public service activity)*.” To help children realize that chemistry is something that exists around them, we also held a chemistry laboratory class for the Wonders of Chemistry as part of the tour.

*Hozo Hut (public service activity):

This is a CSR activity in China that donates a portion of the operating costs of facilities that provide supplementary education and out-of-school learning to children of migrant workers who live in the city but do not have the same access to education and welfare as children born and raised in the city. MCCN has supported the facility since 2020.
