This year’s Northville Central School District’s K-12 STEAM Fair featured projects focused on either inventions or experiments. Following weeks of research and hard work, students proudly presented their results to judges and classmates alike on Tuesday. Projects ranged from a hand-built reverse-osmosis machine to a study of the quality of bottled water vs. tap water to research on green energy, and much more. Prizes were awarded to the top three projects in each age group and category, but everyone who shared in the experience was a winner.
