FY2021 Horikawa River Development Activity Record (5th to 8th)

State of garbage investigation learning

・Following the previous activity, we conducted a "garbage survey learning" with nearby elementary schools.
　I did it.
・First, in the classroom, the type of garbage discarded in Naka Horikawa and microplastics
　I learned a lot about the problem.
・After that, along Naka Horikawa along Naka Horikawa with local people who are volunteering to clean up Naka Horikawa.
　While walking and listening to the story, I checked the actual garbage that was actually discarded.
・The students used the tongs and garbage bags they brought, and said, "The garbage in such a place.
　There was!" While talking out, "There's also here!"
　I was picking it up.
・Like last time, it was a very active environmental learning.

Survey of creatures

・We carried out environmental learning in Naka Horikawa with students of nearby elementary schools.
・They were divided into two groups, and together with coordinators and local people, "creature tone"
　We conducted a "water quality survey."
・In the "creature survey", you will see how to capture creatures, and the coordinator will see fruit.
　I also observed the creatures that were captured.
In the “Water Quality Survey”, a pack test using Naka Horikawa water was conducted to learn how to check the water quality.
　I'm sorry.
・A lot of questions were received from the students, and it was a very active environmental learning.
　I did it.

・We talked about Naka Horikawa River making activities and cooperation with nearby elementary schools.
・Elementary school teachers also participated, and the students were interested in the "creatures" living in Naka Horikawa and the "garbage" discarded.
　I was told that I had.
・As a result of the discussion, environmental learning, "creature research" and "garbage investigation" will be carried out in collaboration with elementary schools as part of this activity.
　Thank you very much.

Completed stone structure

・At two locations in Naka-Horikawa near Shirane Fudoson, we experimentally constructed a stone structured water system experimentally.
　I did it.
・A stone structured water system is a combination of stones of different sizes to produce raw materials in rivers.
　This is a small nature restoration activity that creates a space where creatures can live.
・The purpose of this construction is to breed and grow Kawanina, and to provide nutrients in water by depositing fallen leaves.
　It is to increase the value.
・In the future, we will periodically investigate the presence of Kawanina and the accumulation of fallen leaves.
　I'm going to do it.
