As part of a trip of a lifetime, the 14 students from years 9, 10 and 11, along with teachers Mrs Wait and Mrs Caress, spent five days at Kilambo Primary School building four classrooms with the help of local labour.
School leader Gemma Wait said: “While there is still a lot of work to be completed, (we) have left a lasting legacy to the 600 students and 12 teachers who attend the school each day.
“As well as completing building work, we had time to get to know the community and play with the children. We took football kits which were given to the poorest children.
“The education secretary visited us and our students have requested we maintain links with the school by sending parcels of old uniform and equipment every term.”
Each student had to raise £2,295 for the trip, as well as supplying their own personal kit and paying for vaccinations.
Before setting off, the team had a day of tent building, team activities and choosing roles for each team member during the expedition.
After visiting the capital, Dar Es Salaam, the team undertook the mountainous Baobab Valley trek, accompanied by armed guards.
The young people learned how to cook on an open fire, sourcing their own firewood, experienced putting up and taking down their tents most days, and collected water from rivers or springs, which sometimes had to be treated before it could safely be drunk.
