Scouts, Guides, Air and Royal Marine Cadets will be celebrating the countries that the historic Second World War submarine HMS Alliance visited.
Gosport Stars Showcase takes place on Saturday from 10am to 3pm at the Royal Navy Submarine Museum in Gosport.
Visitors are welcome to join the youth groups in a range of activities ranging from signals and Morse code, to seeing how the Royal Marines cope out in the wild.
Gareth Brettel, education manager at the museum said: ‘This is a fantastic way for Gosport’s young people to showcase some of their hidden talents.
‘They have uncovered HMS Alliance’s heritage by using the museum’s collections to learn more about the countries she sailed to and completed their Scout global challenge badges.’
The event is free with a valid museum ticket.
