By the time kids are 5, they’re developing skills and more-specific interests that open up new gift-giving possibilities. Many 5-year-olds are starting kindergarten, and they’re exploring new subjects and ideas in school for the first time. Toys and kits that let them engage in project-based inquiry—such as performing simple science experiments and exploring nature—can help them make connections between what they’re exposed to in the classroom and what they experience out in the world.
