Q: Please let me know what crate would be the first shipped if I order the science expedition crate today for a 3 month subscription. Thank you.Asked by Graham M., February 2023

STEM Discovery Boxes answered...February 2023

Currently, our first box contains:
Explore the science of hydraulics, Robotics, and Pascal’s Principle of water power by engineering your very own water pressure-powered mechanical claw!
Learn about artist Marcel Duchamp and his Duchamp-Rotorelief optical illusion machine. Can your brain be fooled into seeing something that isn’t really there?
Capillary action, evaporation, and crystallization will bring your prehistoric setting to life. Grow a one-of-a-kind crystal garden right before your eyes!
Those are the 3 projects currently being shipped for our customer's first box. Coming later in 2023 the first box contents may change.
Thank you! We look forward to hearing from you!


Q: regarding Stem Discovery Boxes 3 month subscription, where can I view some of your boxes? This would be my first time with CratejoyAsked by Graham M., February 2023

STEM Discovery Boxes answered...February 2023

Hello! Our cratejoy listing shows many of our projects, but you can also see samples on our website and facebook page. If you would like to know specifically what is in an upcoming box, please contact us via email and we can provide detailed information on the next months box.
Thank you!


Q: Can you choose to send a kit every three months instead of monthly?Asked by Hector C., November 2020

STEM Discovery Boxes answered...November 2020

Yes, you can definitely do that! Once you place your order for a 3, 6, or 12 month subscription, simply contact us with the specific months that you would like the boxes delivered. As of now I'm not sure if cratejoy offers custom ship dates for pay-per-month subscriptions, but we can do so with the 3, 6 and 12 mo. Thank you!


Q: It says 7-12. My grand child is at the upper end. Will these be challenging enough for her?Asked by Ed D., November 2020

STEM Discovery Boxes answered...November 2020

We have many teens, and parents even, who love the projects. We provide a variety of topics and difficulty levels per box. Younger kids may need help with some of the more difficult projects, but tweens and teens will be able to do them independently. Thank you!

Some of the instructions could be clearer but it gave her a challenge. Thanks!

STEM Discovery Boxes said...May 06, 2021

Thank you so much for your review. We are so happy to hear that your little STEMist enjoys the projects and experiments! We strive to provide a range of ability levels to offer activities that kids can do on their own as well as activities that adult and child can do together (kids love that type of quality time) - it's also also great for kids who enjoy doing a more challenging project on their own. We will definitely take note to your suggestion about offering more detailed instructions. We love hearing customer feedback that helps us constantly improve our product. Thank you again for taking the time to review your STEM Discovery Boxes!

My husband and I are both college graduates and he is a science nerd. Yet, we could not get some of the projects to work at all, or as expected. The directions are not always clear or detailed enough. It needs a longer format for instructions than the card to guarantee success.
We bought the Discovery Boxes as part of our science curriculum for our grand daughter who is 7. We are pandemic homeschooling. She is at the young end of the scale for this product, but since she would be doing this all with an adult, we thought the level would be acceptable. Many of the projects are not only above what she can even help with, they are also above her understand of scientific principals.
The concept is great. However, I would caution parents interested to buy in at levels where their child is in the medium to high age range suggested for the kit. I would also recommend that one adult be 'science inclined'. We kept our subscription for the school year and picked the projects we wanted to do.
