Primary Outcome Measures

Name	Time	Method
Handwashing motivation of children (measured as soaping time by digital system).	up to 3 months	Motivation of children, measured as soaping time (activity level) by digital system. Activity level is used as a proxy for motivation.
Handwashing motivation of children (investigated with observation questionnaire for children in kindergarten)	up to 3 months	Motivation of children, investigated with observation questionnaire (covering different steps of handwashing) of children while washing hands in kindergarten.
