Investigating the effects of educational programmes on children’s environmental perceptions has been hampered by the lack of good theoretical models and valid instruments. In the present study, Bogner and Wiseman’s Model of Ecological Values provided a well‐developed theoretical model. A validated instrument based on Bogner’s Environmental Perception (ENV) scale was used to examine the effects of the Sunship Earth programme on the environmental perceptions of fifth and sixth grade students in the US. Paired sample t‐tests showed a statistically significant change toward more pro‐environmental perceptions for all factors described in the model for children who participated in Sunship Earth but not for a control group. Additionally, perceptions were shown to be stable over time for a smaller sample of students.
