A group of school children got a taste of what it is like to be in the Royal Navy during a special day out of the classroom.
The youngsters from St Erth Community School were on a visit to RNAS Culdrose, near Helston, when they were put through their paces by a fitness instructor.
Teacher Chris Armstrong said it had been a fantastic day.
"We're extremely grateful to all the staff at the base for organising such a wonderful learning experience for the children," he said.
A number of class projects were combined for the outing including subjects as diverse as food and healthy eating and the vehicles used by the Navy.
"The trucks and lorries really fired up the children's imaginations," said Mr Armstrong. "It was great to see how a busy air base works.
"You only had to see the smiles on all the children's faces throughout the day to know how much they enjoyed every activity."
Leading physical trainer Leah Ravuoco led the youngsters through a lesson on exercise techniques and staged a special circuit training session. After that came a visit to the Air Engineering School where they saw dissected helicopter engines and tools used to teach navy trainees.
Lieutenant Derek Barr, who runs the Engineering Training school at Culdrose, said: "School visits like this are really important for Culdrose.
"Children get to see helicopters flying over their playground and gardens every day. It's important to engage their imaginations and show them close up what we do."
