Roland-Story biology students recently toured the Prairie Vineyards south of Story City, where they were able to visit with John Miranowski. He explained to the students about the importance of testing soils and practices used to ensure a successful grape crop. “We had a really good visit and tour of Mr. Miranowski’s project that he began over 10 years ago. What he shared with the students ties directly in with our units of study this semester,” said Brad Taylor, biology instructor. Students in this biology section have been using the STEM (science, technology, engineering and mathematics) upscale program called CASE (curriculum for agricultural science education) as a basis of this semesters studies over plant and soil sciences. Most recently the students have completed a unit on taxonomy and will begin a unit on “the growing environment of plants.”
