Little Passports Science Junior review

Most science boxes on this list start at age 8, and Little Passports Science Junior covers the years before that. It is designed for ages 5 to 8, and each monthly kit explores a science theme, with coral reefs, robots and nocturnal animals named as examples, using experiments and comics. Pricing is published in US dollars for all three plans: $32 per month month to month, $27 per month billed $162 every 6 months, and $25 per month billed $300 every 12 months, all with free shipping. You can cancel or pause anytime, and Little Passports suggests moving up to Science Expeditions after 24 months, which keeps the same characters and format for kids 8 and up. The trade-off is depth: projects are simpler than CrunchLabs or MEL Science by design. For a 5 or 6-year-old who is just learning to read instructions, that is the point.
