    Customer review shared with STEM Discovery Boxes

  • A boy at a table smiling beside a science experiment with blue liquid foaming out of a bottle onto a plate

  • These boxes are amazing

    My students were fully engaged and couldn't wait to explore each project. Clear directions, awesome results, and tons of learning packed into every box. Highly recommend.

    Customer review shared with STEM Discovery Boxes

  • A smiling boy at a table next to a dinosaur model made of green and blue modeling clay, with more clay pieces scattered on the table

  • Almost better than Disney

    Got this for my grandson and he said the only thing better would be Disney. He's made VR goggles, a hydraulic claw, and more. Creative, exciting, and absolutely worth the money.

  • A boy sitting on a couch holding up a small wooden build with a wire attached, next to a STEM Discovery Box

  • Perfect gift for curious kids

    My daughter built glowing bouncy balls and a VR viewer, all by herself. Easy-to-follow instructions explain the science behind the fun. We can't wait for next month.

Commonly Asked Questions

How many projects come in each box?

Every STEM Discovery Box includes 3 complete hands-on projects plus 3 science lessons, not a single activity. Each project arrives with its own pre-portioned supplies, so one box gives a child three full experiments to work through across the month, and a 12-month plan delivers 36 projects in total.

Do the kits include everything we need?

Yes. Each box ships with all the supplies a child needs for all three projects, down to the batteries. There is no prep work, no printing, and no trip to the store before you start. Open the box, read the first card, and begin the experiment straight away.

What ages are STEM Discovery Boxes for?

The kits are designed for kids ages 5 to 12+. Projects are matched to an age tier, so younger children and older kids each receive experiments suited to their level. Every box builds the same underlying science skills, just pitched at the right difficulty for the child.

How much does a subscription cost?

Three months is $109, six months $209, nine months $289, and twelve months $359 for 36 projects, which works out at about $30 a box. Shipping is free on every plan. Month to month is $37.95 with no commitment, and you can cancel at any time from your account.

How much is shipping?

Shipping is free on every box, with no minimum order and no surcharge on longer plans. Your first box is shipped within 1 to 3 business days of ordering. After that, boxes ship with the monthly batch between the 1st and the 5th of each month.

How do I cancel my recurring subscription?

You can cancel at any time from your account, and month to month plans carry no commitment at all. Term plans run for the length you chose and then renew, unless you switch auto-renew off first. Contact us and we will process the cancellation for you.

Can I use ESA or school funds to buy them?

Yes. STEM Discovery Boxes is fundable through major ESA and education-funding programs, including Step Up for Students (SUFS), ClassWallet, and Arizona ESA. Eligible families can pay through their program's marketplace, or be reimbursed with the itemized receipt we provide. Schools can purchase with a purchase order and a W-9.

Can I order a set number of boxes without it renewing?

Yes. Schools, camps and event organizers order by quote, not by subscription. Tell us the quantity and date and we send a written quote and an invoice, and we accept purchase orders. For gifts and family plans you can opt out of auto-renew at checkout, so the plan runs only for the term you paid for.

Do your STEM projects align with school standards?

Yes. Every box is designed to align with NGSS, the Next Generation Science Standards, alongside Common Core, TEKS, SOL and other state frameworks. Each box includes 3 science lessons alongside the 3 projects, so a teacher or parent can connect the hands-on work to what a child is expected to learn.
