open-ended imaginative play, exploration and social engagement. Toys with the quality of open-endedness can be used by children in a variety of ways and at different ages and developmental levels. Educational toys vary widely in terms of their open-endedness and their potential for exploration, imaginative play, and social engagement. Play theorist Brian Sutton Smith, who advocates for free play, has asserted that "the plans of the playful imagination dominate the objects or the toys, not the other way around." Toys whose design is more heavily specified and restricted may be less intuitive for children to use, and require more engagement and support from adults. Many studies of educational toys report that the effectiveness of a toy is more related to the involvement and guidance of adults, or to the child's intellectual level, than to the toy itself.

They are miniature chemical laboratories for boys and girls... this kind of play is most interesting and amusing to every youngster". In 1921, Chemcraft advertised a "Sachetcraft" set for girls that could be used to make perfumes and cosmetics. In the 1950s, Gilbert marketed a pink "Laboratory Technician" set for girls. It contained a microscope and factory-prepared slides, rather than the raw materials to make one's own slides for viewing. However, the manual contained identical information to that given to boys.
