PARTICIPANTS of the Ballet Development Scheme in the New Territories will attend a six-day dance camp at the Sai Kung Outdoor Recreation Centre early next month to prepare for their grand performance next month. The camp will take place between April 7 and 12 as a climax to the scheme's ''Making Dances'' project, launched by the Regional Council and the Education Unit of the Hongkong Ballet Company. It will offer a valuable opportunity for the 181 students aged between eight and 20 to share their experience and show off their respective works which will be performed at the Sha Tin Town Hall on April 11. According to Hongkong Ballet education administrator Pele Yuen, this will be a special gathering for the young ballerinas. Not only will they get to enjoy the wonderful camp facilities and fresh air in Sai Kung, but also they will be doing their rehearsals in a wonderful environment. ''Normally, students will not be offered further opportunities to have such a large gathering when their classes are over.'' At the camp, students will also take part in activities like badminton, table-tennis, roller-skating, and archery. Evening events include variety shows and games. ''We hope each of them will have good and sweet memories to take back after the camp,'' Mr Yuen said. The students will stage a series of 10 dances at the Sha Tin Town Hall where parents will be able to see what their children have learned over the past few months. Apart from participants, some 40 students from primary and secondary schools in the outlying islands have also been invited to stay in the camp. They will learn some basic knowledge about dance and its appreciation through the instructors.
