Top Picks

KiwiCo

The most established name in kids' subscription boxes. Different lines for different ages: Panda Crate (0-24 months), Koala Crate (2-4), Kiwi Crate (5-8), Doodle Crate (9-16+). Each box includes 2-3 projects with an instructional magazine.

Little Passports

Focuses on geography and world culture in addition to science. The "Science Junior" line covers topics like space, oceans, and dinosaurs.

Mel Science

Chemistry and physics experiments with real lab equipment. More advanced than most boxes — best for ages 10+. Very hands-on and impressive results.

Making the Most of Subscriptions

Schedule a regular "STEM night" when the box arrives. Do projects together initially, then encourage independent exploration. Keep a STEM journal where kids document their projects and what they learned.
