The STEM (AJMO!) project will strengthen the capacities of 7 involved civil society organisations from 7 Croatian counties for the purpose of implementing STEM popularisation activities among children, young people and citizens. With the help of the scientific community, partners will design 20 topics for 100 multi-day workshops and 10 themes for 60 one-day events that will be piloted by 3,000 children and young people. A STEM laboratory will also be organised, which will remain a permanent setup focused on the popularisation of STEM.
