The Promoting Radio Astronomy in Ghana through School visits and Astronomy Clubs (PRAGSAC) project was an intervention to promote astronomy education in schools in Ghana. It was initiated by a group of enthusiastic students who were trained in radio astronomy and astrophysics under a Royal Society/Newton Fund UK project termed Development in Africa with Radio Astronomy. The team's aim is to expose school children to astronomy and to increase their interest in the sciences. Approximately 800 school children from seven junior high schools were positively impacted by this project. Astronomy clubs were formed in the selected schools with practical astronomy lessons taught. The kids visited the largest single radio telescope in Africa at Kuntunse in Accra and were amazed about the engineering and the science that it undertakes. For the patrons of the clubs, a teacher training workshop was organised for them, so as to equip them to manage the clubs. The feedback from students and teachers was exceptionally positive, implying that the PRAGSAC project has helped inspire more students to pursue courses and consider careers within the sciences.
