Getting kids interested in science at an early age is important for both their future career possibilities but also enabling them to develop a curiosity for how things work in the world around them. Sparking a child’s enthusiasm can mean finding toys that match up with their interests as well as offering them fun and creative scientific play.

So, whether they’re into creating products from raw materials such as candles or slime, or curious about rocks and the forces that make the world work, we’ve found the 10 best science kits for girls to play with in 2021. Because we also love science, we’ve taken a forensic approach to our research and filtered out the fake reviews so you can trust that our recommendations have been verified by real people.
