It was organized by the Ghana Education Service (GES) with support from the metropolitan, municipal and district assemblies.
It provided the platform for the students to have hands-on training in electronics, fruit juice and liquid soap making.
Added to that, there were discussions on adolescent sexuality, career guidance and counseling, industrial and educational tours.
Mr Joseph Onyinah, the Ashanti Regional Education Director, performing the closing ceremony, said science and technology was critical to the progress of a developing economy like that of Ghana.
It was therefore important to make deliberate efforts to get the youth to develop interest in the study of science and mathematics.
He said it was by doing this that they would acquire the relevant scientific knowledge and the technical know-how to move the nation forward.
Mr Gabriel Antwi, the Regional STMIE Coordinator, said the programme which at its start in 1987 was organized exclusively for girls, has now been diversified to include boys.
He said the expectation was that students would become more innovative to address issues of poverty, health, rural development as well as agriculture, green energy and other challenges in the communities.
Mr Sadique Boateng, the 2008 National Best Teacher, appealed to his colleague teachers to adopt teaching methods that would make the learning of mathematics and science simple and exciting.
He advised the students to be disciplined and exhibit good morals since that was the path to academic success.
