This paper reports findings from a study that evaluated the impact child-centered discovery trolleys have on 4-8 year old children's museum experiences. The Queensland Museum developed a set of resource trolleys to introduce young visitors to museums and their collections. Findings from this study add to the body of knowledge on this topic and may have important implications for designing museum experiences that stimulate children's interest in museums and increase learning outcomes. A copy of the questionnaire used in the study is included in the appendix of this paper.
