Klasy ósme na lekcji chemii przeprowadzały doświadczenie techniką chemii w małej skali. Na probówkę narysowaną w karcie pracy należało nanieść po kropli odpowiednich roztworów umieszczonych w pipetkach. Mieszane parami roztwory zabarwiały się na różne barwy ilustrując zachowanie się wskaźników w kwasach i zasadach.
