This study examines the science learning experiences across the lifespan of two groups of college students: adults with intellectual and/or developmental disabilities in a post-secondary inclusive program, and adults in a preservice secondary education teacher candidate program. Data, in the form of personal narrative science stories were collected using a paired-interview approach in which students from each group interviewed one another about their science learning across their lifespans, and recorded responses using an online form. Across the stories, several clear themes emerged. Similarities and differences were found across and within the groups and are shared in a narrative format. Trends that emerged both across and within groups are shared, and recommendations are made for current and future teachers for best practices in teaching science to all students, including those with a variety of disabilities.
