This article describes an inquiry science lesson that was sparked by a child's question. In this school a science specialist (author 1) team teaches science with the kindergarten class teacher (author 2) for 1 hour per week. The class teacher integrates science at other times during the week. To foster the kindergarteners' interest about a science topic, the class teacher (Cassandra) encouraged the children to bring 'something that moves' for News time. Isabella brought 2 balls: a 'super-bouncy' ball and a 'normal' (tennis) ball. Isabella wanted to show her classmates that one of the balls bounced "much" higher than the other one. Isabella was disappointed that neither ball bounced as high as they did at home. This puzzled the class and they wondered why this happened. Cassandra suggested they could ask the science specialist teacher (Chris) if she could explain this observation. Together, the children and teacher devised and sent an email to Chris.
