Waipahu High School in Hawaii, Uwajima Higashi High School, and ourschool have been conducting an international joint research project on waterpurification since last year.  This time,the progress of research in the three schools was mutually presented andconfirmed.   In this school, we tried tofabricate a variety of filtration devices and determined the performance of thedevices through pack tests.   Inaddition, Uwajima Higashi High School and Waipahu High School reported on theirefforts to purify rivers using oyster shells and native Hawaiian plants “Akulikuli”,respectively.   And then, we have a lively exchange of ideas.　

Auther’s opinion:  At the third exchange meeting, the studentsbecame accustomed to asking questions in English and were able to interactactively.  I would like to continue to domy best with them. 209―Kaito Matsutomo
