"Children's Adventure 2019 Summer Vacation Children's Environmental Science Class" was held.

The Institute for Environmental Science held the Children's Adventure 2019 Summer Vacation Children's Environmental Science Class for elementary and junior high school students in the city. . Through experiments and observations through programs on themes such as alien organisms, air and water pollution, and microplastics, they had various experiences related to the environment.

• Date of implementation: August 15, 2019
• Implementation site: Yokohama Institute of Environmental Science (5th floor, Shibusawa ABC Building 1, Ebisu-cho, Kanagawa-ku, Yokohama)
• Number of participants: 24 elementary and junior high school students (36 parents, etc.)

We will introduce the contents of the experimental note (with answer) and the state of the day for each program.

We simulated a survey of substances that caused river turbidity accidents.

We observed small plastic waste drifting on the coast and thought about ways to reduce plastic in our daily lives.

I learned how the air changes and how to feel cool by observing snow crystals and experimenting with vaporizing liquids.

I used a microscope to find out the types of ants that are close to me. I also saw a sample of fire ants.

• The electron microscope was amazing to be able to take pictures.
• It was fun to put the BTB solution for the pH test and COD back test in which water quality accidents occurred, and to inhale and mix water.
• Arinko observation surprised me that there are 300 kinds of ants in Japan. It was an insect close to me, so I wanted to see it in more detail.

Thank you very much to everyone who responded to the questionnaire. I would like to refer to it so that future experimental classes can be made more enjoyable.
