Abstract The purpose of the study is to contribute knowledge about working with physics in preschool, and how the youngest children perceive natural science phenomena, and to make visible how educators work with the subject of physics. Our focus is forces, and we therefore designed and allowed the children and educators to conduct experiments on, gravity, static electricity and magnetism. The study involved 19 children, aged 1 to 3 and 5 educators.  The data collection method for this study consists of observations of the children when they experiment, as well as semi-structured with the educators. We used video recording when conducting the experiments and voice-recording when interviewing the educators. The interviews used a phenomengraphic methodological approch in order to capture preschool teachers different experiences of physics.  The youngest children expressed themselves with body movements, mimicry and the older children also expressed hypotheses and reasoning. The results of the interviews show that educators to a large extent feel unsafe when it comes to science in preschool. Unsure about how and what to say, and how to perform spontaneous physics aktivities, and unsure what level is appropriate for the younger children.
