JOIN USLearning to tie a knot or read a map were once some of the essential skills taught to children as they grew up. But such practical lessons are in danger of being forgotten, says the study by the Scout Association.
Just one in five children -- or 20 percent -- in Britain could tie a reef knot or repair a flat bicycle tyre.
If they went camping, only half of them knew how to put up a tent, use a compass or cook a meal, reports the Daily Express.
However, nearly all the children could send an email and download music.
This suggests learning practical skills has been replaced with modern techniques.
Survival expert Bear Grylls, also the Chief Scout, has urged children to go back to basics and learn skills which will help them throughout life.
"Practical skills are at the heart of scouting. From first aid to cooking a meal, we encourage all young people to learn skills they can use in life. Having these skills helps them prepare for whatever life throws at them," he said.
Researchers questioned 508 children, aged eight to 15. They also spoke to 2,020 adults.
Most of the people surveyed believed teenagers lack the same practical skills they themselves had at that age.
The survey was carried out ahead of an overhaul of the Scouts' "Pioneer" badge, which incorporates some of the lost crafts.
The badge, which is being relaunched in partnership with the Discovery Channel, teaches knowledge of knots, blocks, lashings and anchors.
There are 400,000 members of the Scout Association in Britain. It was set up by Lord Baden-Powell in 1907.
