The pupils are part of the ruMAD? project supported by the Tasmanian Centre for Global Learning.

Pupils and teachers involved in the program identify local and global problems and aim for positive change by running projects.

Trevallyn Primary School pupils will host the Youth Action Conference at the University of Tasmania's Newnham campus on September 2, where pupils from across the North will display their work and attend workshops.

Trevallyn grade 4-5A teacher Peg Smith said pupils had this term been working on projects they developed which aimed to make a positive difference to the world.

She said the projects included fund-raising to help street kids in the Philippines, promoting good eating by making healthy snacks and encouraging shops to donate surplus food to people in need.

Other projects have included developing a litter-free lunch box, running physical education sessions and developing mental challenges to keep their minds active.

"It's been a great thing," Mrs Smith said.

"The kids have had a great time doing it and the kids have gained a lot from it.

"It has involved organisational skills, working in a group and having lots of fun.

"And they have made a difference in their own lives.

"It's about looking past their own lives and making a difference and they have really learned a lot about that."

The pupils also developed a vision for a better world.

It reads: "Our vision is to live in freedom and peace in a world where we can spend time with family, friends and loved ones and have shelter from the elements. We want to be able to play and do things we love like drawing, creating things and playing music."
