Canadian born women are severely underrepresented amongst science students and researchers in Canada. This is due in part, to the cultural construction of science as "unfeminine" and “for boys.” This sentiment emerges when girls are as young as 6 years old. Educational toys are often the first avenue in which children are introduced to and engage with scientific culture. Parents have traditionally used gender symbols in toys to teach children gender roles, appropriate values and actions. The current study investigates the possibility of science toys as a socializing agent for gendered beliefs about science. It does so, by completing a content analysis and qualitative analysis of gender and science symbols within 400 science toys. This analysis found that science toys contained a substantial number of masculine symbols; including masculine mentors, colours, themes and a greater number of boys on packages.
