Year 7 and 8 pupils from 10 contributing schools around the area visited South Otago High School as part of the technology curriculum.
''A lot of them [pupils] come off farms but then very few of them know what happens to wool once it's off the sheep,'' Mrs Elder said.
She said The Woolshed had been a good addition to the teaching she was already doing about the use of natural fibres.
''70% of the world's clothing comes from plastic ... it's good to make students aware of what's going to happen at the end and think about it when they buy things.''
The Woolshed also aimed to teach pupils about what wool could be used for in the future.
''It's important for people to know about this natural product ... it's a natural solution to a growing problem,'' Mrs Elder said.
Wool in Schools project manager Vicki Linstrom said The Woolshed had previously been in the North Island for three years but had only been in the South since January.
She said it was the brainchild of an ex-primary school teacher who wanted to teach the next generation about wool.
''Wool is much more than socks and blankets ... it can be used as booms in oil spills, face masks, biodegradable weed mat and more,'' Ms Linstrom said.
Although the movable classroom was being utilised in rural schools, she hoped to promote it more in urban schools.
The Woolshed is already booked for the rest of 2018.
