  2. Human Ingenuity AOI • Human ingenuity allow students to focus on the evolution, process and products of human creativity and their impact on life and society. Human ingenuity provides opportunities for students to appreciate and develop in themselves the human capacity to create, transform, enjoy and improve the quality of life. • Human ingenuity is also about how people use their creativity and how they think and this presentation will relate to human ingenuity because it will show how people used their creativity and their thinking skills to discover things that have changed the world and the scientific and outside society.
