The curriculum fair at Trinity College Nabbingo (TRICONA), held at the school along the Kampala-Masaka Road in Wakiso District on Saturday, March 22, 2025, featured captivating inventions conceived and developed by the students.
One of the standout innovations was the "garbage fountain" displayed by students from the Art and Design Department. Equally impressive was the Yo-Soil app, developed by ICT students, and an urban farm designed by the Biology Department.

Students from the Luganda Department exhibited traditional foods such as sweet potatoes, white yams (balugu), and cassava. They also demonstrated the preparation of luwombo dishes, including chicken, beef, and groundnut stew. Visitors to their stall had the opportunity to sample some of the meals.
Exhibitor Betty Nalubowa (S2) explained, “Our local foods are incredibly nutritious and healthy. They also last longer in the body compared to junk food, which leaves you hungry again after just an hour.”
The Christian Religious Education (CRE) students surprised attendees by showcasing local delicacies such as cassava and maize porridge, traditional brew (mwenge bigere), banana juice, millet and carrot cakes, and pancakes.
English Literature students captivated the audience with their film Sunset at Dawn, which highlighted challenges faced by the girl child and celebrated the achievements of female empowerment.
The Biology students, led by ‘Dr’ Nayebare Hope (S5), hosted an interactive health camp, where they measured visitors’ blood pressure and provided health tips.

Students from the Agriculture Department presented their innovative TRICONA 1 Composite Tumbler, which processes organic manure in just six weeks—an improvement on the standard four-month process that often delays agricultural productivity.
They also introduced a multifunctional agricultural storage facility designed to protect cereals from aflatoxin-producing fungi.
Other exhibitions
Home Economics Department: Students produced a variety of yoghurt flavours, including strawberry, vanilla, soya, and milk, as well as jams made from jackfruit, pawpaw, pineapple, and ginger.

Commissioner Atuhaire impressed
The commissioner for secondary education at the Ministry of Education and Sports, Juliet Atuhaire Muzoora, expressed her admiration.
“I am excited to see what the new competence-based curriculum is achieving here. I thank the headteacher, Mrs Lwanga Immaculate Nassozi, the staff, the board, and the parents for supporting its implementation. These innovations highlight the beauty of integrating knowledge and skills, with each subject contributing to the full realisation of the other. I also thank my daughters, the students, for their creativity. Soar higher and higher to become great ladies of substance,” Atuhaire said.
The headteacher, Immaculate Nassozi Lwanga, assured Atuhaire that TRICONA remains committed to implementing the curriculum with even greater dedication.
She also announced that the school had recently won two competitions: the Science Exhibition hosted by SMACK and the Kampala Archdiocese Pro-Life Contest, both held on March 16, 2025.
The exhibition was held under the theme: Empowering the Girl-Child Holistically Through Innovation for Sustainable Development.
