Reiwa Year 3, on Sunday October 24th,we discussed the experiment at data with Waipahu High School students in Hawaii(4 students), who are conducting international research on purification ofwater, for a period of one hour. Uwajima Higashi High School Students（6 students）,who have engaged in international relationwith Hawaii.  After they explained the experimentaldata from each country, a question and answer session was held.  Our High School students asked questions proactivelyabout the followings: COD value increase at the downstream in Kapakahi River inHawaii after rain, and the reason why TH value tends to increase, and so on.  This research will be summarized in a paperand exhibited in a domestic contest.  Fromnow on, we will discuss the topic again, continuing to conduct experiments forthe international contest held next year in December.

Impression:This discussion was a valuable experiencefor me.  It was the first time for me tospeak English outside of class.  So I wasvery nervous.  However, Uwajima HigashiHigh School students were smiling and friendly.  I was surprised to see that they are alsousing plants to tackle water issues.  I thoughtit was an interesting idea.  We'll do ourbest, too. ―　Kaio Matsumoto, Class 109
