[DeepL:] Horizontereignis is a non-profit UG that was founded in 2012 by two planetologists with doctorates and an educator to teach natural sciences to preschool and elementary school children as well as adolescents and adults in an age-appropriate, creative and professionally competent manner. The focus is on fostering curiosity about, fun with, and enthusiasm for scientific and technical topics through exploratory experimentation and active experience and discovery. To achieve this, Horizontereignis employs a qualified team of scientists and educators who work as a team to conduct courses, projects and events on site at various schools, daycare centers and extracurricular educational institutions. In addition, scientific basics are combined with cultural and creative topics and contents in various projects. Through self-executed technical, scientific and artistic processes, the children can experience the various subject areas with all their senses and learn to use artistic content as a means of expression for themselves. In addition to promoting scientific and technical understanding, the participants' creativity, fine motor skills, social and language skills, improvisational ability and motivation to solve problems creatively, as well as their confidence in their own abilities are thus activated and promoted.
