In a cooperative class between Ehime University and our high school,  first- and second-year students from the science and mathematics department attended lectures and laboratory tours.

   Lecturer: Dr. Yuko Kamika (Associate Professor, Department of Food Production Science, Graduate School of Agriculture, Ehime University)

Content:

(1) Observing the sorting of tomatoes harvested at a plant factory

(2) Collecting data sorted by a sorting machine

(3) Significant difference test using individual weight data (lecture and exercise at the Media Hall of the Center for Information Technology)

   First, we visited a solar-powered plant factory. Tomatoes were grown in a tall plant factory with glass walls, different from ordinary plastic greenhouses. The tomatoes were planted not in the soil but rather in rock wool and hung from above, making it look more like a "factory"  than a "field”. By controlling the plants’ growing environment, they are able to supply farm products at stable prices and quality throughout the year.

   Next, we also observed the sorting of harvested tomatoes by weight.

   After the tour, the students moved to the Information Media Center, where they had a lecture on significance tests while doing exercises using spreadsheet software.

   I believe that the methods we learned for data processing will be valuable for our future research.  ( 209 Ochi Kotaro, Sueda Yuito ) )
