e² Young Engineers Canberra the e² Birthday package is a fun and educational activity for children. The children experience and have fun building with Lego throughout the activity. This building activity provides the children with a small taste of the world of Lego and enables them to develop and think creatively as they create the things that they have imagined. In addition, the children work in groups during the activity, practising cooperation and teamwork. Finally, we end with a fun birthday celebration. All held at the location of your choice!
