In spring 2011, Dr. Brankovic and his graduate students have visited North Shore Senior High. During this visit, they conducted the lectures and experiments on electrochemical determination of Avogadro’s constant (NA). After the lecture, the high school students were quizzed on different aspects of the conducted experiments, data analysis, and calculations leading to a wider discussion with high school students on important questions about education, life, and science. The PDF of Dr. Brankovic’s lecture can be downloaded here (PDF) while the illustrations of the visit and activities are best described in pictures above.
