What Is KiwiCo?
KiwiCo began in 2011 when founder Sandra Oh Lin wanted to create hands-on learning experiences for her own children. The company has since grown to serve millions of families worldwide. They offer monthly subscription boxes focused on STEM, art, and exploration.
Unlike academic-focused science programs, KiwiCo emphasizes creativity, problem-solving, and the joy of building things. Each box contains a complete project with all materials included. It has clear instructions and educational content explaining the science behind the activity. This hands-on approach aligns with research from the National Science Teaching Association, which emphasizes the importance of experiential learning in science education.
KiwiCo Lines for Younger Children
Panda Crate (0-24 months)
Panda Crate focuses on early developmental milestones with age-appropriate toys and activities. Each box includes Montessori-inspired materials and a parent guide. The guide explains developmental benefits and suggests activities to extend learning.
Best for: Parents wanting intentional, development-focused play materials without researching and purchasing items separately.
Koala Crate (2-4 years)
Koala Crate introduces preschoolers to hands-on exploration. Projects are simple enough that kids can complete them with minimal adult help. Activities focus on early science concepts like colors, textures, and cause-and-effect relationships.
Best for: Preschool homeschoolers who want structured activities without heavy parent involvement.
Kiwi Crate (5-8 years)
The flagship line, Kiwi Crate, delivers projects blending science, art, and engineering. Children build working projects like robots, weather stations, and musical instruments. They learn underlying concepts while building.
Best for: Elementary homeschoolers seeking supplemental hands-on science activities.
KiwiCo Lines for Older Students
Tinker Crate (9-16+ years)
Tinker Crate focuses on engineering and science with more sophisticated projects. Students build things like hydraulic claws, electronic circuits, and trebuchets. They learn physics and engineering principles along the way.
What we loved:
- Projects are genuinely challenging and rewarding
- Clear connections to scientific principles
- Builds patience and perseverance with multi-step construction
- Finished projects are functional and fun to use
Best for: Middle schoolers who enjoy building and want hands-on science supplements.
Eureka Crate (14+ years)
Eureka Crate targets teenagers and adults with serious engineering projects. These boxes challenge students to build complex mechanisms. They also help students understand advanced concepts. Past projects have included mechanical clocks, motorized vehicles, and architectural structures.
Best for: High schoolers interested in engineering, physics, or maker culture.
Doodle Crate (9-16+ years)
Doodle Crate focuses on art, design, and creativity rather than pure STEM. Projects include textile arts, jewelry making, and design challenges. While not strictly science, it develops valuable creative and fine motor skills.
Best for: Creative students who prefer art-focused projects over engineering.
How KiwiCo Fits Into Homeschool Science
KiwiCo works best as a supplement to your primary science curriculum rather than a replacement. The boxes don’t provide systematic coverage of science topics. They lack assessments and the depth needed for full education. However, they excel at making science engaging and hands-on. For complete curriculum options, see our hands-on science curriculum guide.
Integrating KiwiCo With Curriculum
The most effective approach coordinates KiwiCo projects with your regular curriculum. When studying simple machines, use a Tinker Crate project involving levers and pulleys. When exploring chemistry, supplement with activities from KiwiCo’s science kits. This coordination reinforces textbook learning through hands-on application.
Using KiwiCo for Science Enrichment
Many homeschool families use KiwiCo during summers or breaks. It maintains science engagement without formal curriculum. The monthly delivery creates natural pacing. Projects provide meaningful learning without lesson plans.
KiwiCo for Reluctant Learners
Students who resist traditional science instruction often embrace KiwiCo. Building tangible projects feels different from worksheets and textbooks. According to the National Center for Education Statistics, hands-on learning experiences can significantly improve student engagement, especially for students who struggle with traditional instructional approaches. Success with hands-on projects can rebuild confidence and enthusiasm for STEM subjects.
What We Love About KiwiCo
Excellent Value
At $20-25 monthly for most lines, KiwiCo provides substantial materials and well-designed projects. Purchasing equivalent supplies separately would cost similar amounts. And you wouldn’t get the curated experience and instructions.
High-Quality Materials
KiwiCo materials are durable and thoughtfully selected. Projects hold up to regular use. Components fit together properly. We’ve rarely encountered missing pieces or quality issues.
Clear, Child-Friendly Instructions
Instructions use clear illustrations that children can follow independently. Our 8-year-old completes most Kiwi Crate projects with minimal help, building confidence and independent learning skills.
Meaningful Educational Content
Each box includes a magazine-style booklet explaining the science behind the project. These aren’t just craft instructions; they’re genuine educational resources that extend learning beyond the build.
Flexibility
KiwiCo allows easy subscription management: pause, skip months, or switch lines as children’s interests change. This flexibility suits homeschool schedules that don’t always align with monthly deliveries.
Potential Drawbacks
Not a Complete Curriculum
KiwiCo cannot replace a comprehensive science program. The projects don’t follow a scope and sequence, build on each other systematically, or provide assessments. Use it alongside, not instead of, formal curriculum.
Projects Accumulate
Finished projects need somewhere to go. Our house accumulated completed KiwiCo builds until we established a policy of keeping favorites and recycling others. Plan for storage or turnover.
Varying Project Appeal
Not every box excites every child. Some months bring projects that match your student’s interests perfectly; others feel less engaging. The variety is generally positive but occasionally disappointing.
Environmental Considerations
Monthly subscription boxes generate packaging waste. KiwiCo has improved sustainability, but environmentally conscious families should consider this ongoing impact.

Tips for Getting the Most From KiwiCo
Coordinate With Curriculum
Review upcoming KiwiCo themes (available on their website) and schedule projects to align with related curriculum topics. This integration deepens learning impact.
Extend the Learning
Don’t just build and move on. Use completed projects for experiments, demonstrations, and extended exploration. A trebuchet becomes a physics lesson on projectile motion and potential energy.
Document Projects
Have students photograph builds and write about the process. This documentation creates portfolio evidence while reinforcing learning through reflection.
Consider Gift Subscriptions
KiwiCo makes an excellent gift from grandparents or relatives looking to contribute educationally. Monthly deliveries extend the gift throughout the year.
