Children and teachers are a very important group for outreach activities related to the IDBHP. Children are not only curious about nature and eager to learn, but they will also shape the future. The IDBHP celebration is anopportunity to raise their awareness of the significance of nature conservation, allowing them to pass the message on to their classmates, friends and relatives. Information about harbour porpoises can be presented to children in a short talk, a poster or a PowerPoint presentation. Alternatively, a documentary can be shown. It is important to make learning interesting and an active experience, for example by including games or competitions. Quizzes, crossword puzzles and drawing contests are often popular and simple to organize.

For example, at Hel Marine Station in Poland, LOTOS S.A group, Hel Marine Station’s sponsor, prepared a series of learning activities especially for children. They constructed a special "House of the Harbour Porpoise", which was painted by children, a series of quizzes and face painting amongst other activities. The Lithuanian Sea Museum in Klaipėda, Lithuania, organized a seminar for children in 2009, which took place in its dolphinarium. The theoretical part was thus complemented by a practical part in which children could draw comparisons between the Baltic harbour porpoise and the Bottlenose dolphin being kept in the dolphinarium. Please note: Care should be taken not to support facilities that receive dolphins captured in the wild or that do not conform to international standards, such as those set by the European Association of Aquatic Mammals (EAAM) or the Alliance of Marine Mammal Parks and Aquariums (AMMPA).

Other ideas can include:

- Balloons with harbour porpoises on them.

- Fun zone with various activities mingled with displays of, for example, alternative fishing gear.

- Art and drawing activities for children.
