STEM Discovery Boxes

What's in the box: Three science projects on different topics, each with pre-portioned supplies including batteries, photo instructions, and a matching science lesson.

STEM Discovery Boxes sends three hands-on science projects each month, which is more than many kids' science subscriptions that ship one or two. Each project comes with step-by-step photo instructions and a short science lesson. The company says all supplies are pre-portioned and included, down to the batteries. For busy parents and teachers, that means a child can start the day the box arrives without a store run or prep work. The kits target ages 5 to 12+, and the company says they align with NGSS and Common Core standards. A free video library supports the projects, with walkthroughs by K-8 teacher Mike R. (@ThatSTEMGuy) and YouTuber Jake Makes. Family plans start at $29.92 a month with free shipping, and the subscription is month-to-month with cancellation anytime. Homeschool and school plans start at $28.90 per student per month. The service also accepts ESA funding and purchase orders, and it takes bulk event orders of 25 to 1,000+ kits. Gift subscriptions start at $109 for three months. The site says it has over 100 projects in its inventory, but it does not explain how difficulty scales across such a wide age range. Because three projects share one box, individual activities are likely smaller in scope than single-project kits.
