Best Science Kits for Ages 5-8

Kids ages 5-8 are at a crucial time in their understanding of science, math, and engineering. They're old enough to grasp how big ideas like the solar system and flight, things that perhaps once seemed magical, have scientific properties that allow us to explore outer space and build rocket ships. Kiwi Crate allows children in 1st, 2nd, and 3rd grade to begin a hands-on discovery of physics, chemistry, biology, and more, with fun projects that they can assemble themselves.
