For this drop-in activity, part of the gallery is transformed into a recreated classroom setting, complete with chalkboards, benches, and replicas of vintage posters. Visitors can step inside and experience how health and sanitation were once taught in Philippine schools. Throughout the day, short “mini-lessons” are offered by museum staff, using original textbook excerpts and exercises adapted for modern audiences.

Anyone can participate—children may be asked to recite simple rhymes about handwashing, while adults can try writing old slogans in chalk or solving historical “health quizzes” lifted from century-old schoolbooks. The event blends playfulness with education, showing how civic values were once taught in simple, memorable ways. Because it is a walk-in program, visitors can join at any time, spend a few minutes or linger longer, and leave with a deeper appreciation of how every drop of clean water carried a public lesson.
