My grandson loves them and my husband loves helping him put them together.  It is hard for him (my husband) not to just do them himself, because he likes them too. My only question would be: Do you make STEM boxes for 76 year olds?  I would get one for my husband.

                                                 These stem kits have been great

                                                My boys enjoy the experiments. Less Tv Time has been great.

5.0 out of 5 stars Fun and engaging!

My 8 year old son received this as a gift and absolutely loved it! He was engaged for hours. It was great that it came with multiple projects. Highly recommend!!

I just wanted to send you guys a note and say how much we love your science boxes!! The Hydraulic Powered Excavator in this months box was AWESOME! This was our favorite experiment of all time! Your kits are top notch, the experiments always work, and I love how everything comes organized for each experiment! Just wanted to pass along a rave review and thanks for a fabulous product! My boys look forward to their monthly box more than almost anything else! All the best.

We do look forward to getting the box each month.  We also get Kiwi co, but I really think yours is the better experience.

I just placed and received my 2nd subscription.  The 1st in 2018 was for 6 months, the 2nd in 2019 was for 3 months.  The projects are amazing — fun and easy to implement, attention-grabbers for the kids, and loaded with “ah-ha’s” and learning points.  If you’re looking for an affordable mechanism for having fun with your kids or grandkids and teaching them the mysteries of science and the joy of discovery at the same time, then look no further than The Stem Kits.  I hasten to add that their customer service is of the same quality.  My inquiry to the company about a duplicated order was responded to both swiftly and courteously.  I highly recommend Stem — pretty impressive product and company.

Love these!

My son has loved to get these. Most boxes are used right away and he has respurposed some of the projects. Great thinker tinker boxes! We chose these boxes for christmas gifts instead of toys and he now gets excited when they are in the mail box!

As soon as this box arrived my husband and grandson opened it and completed most, if not all, of the projects that day.

There wasn't any description but I took a chance and ordered it. My 7 and 4 yr old grandsons really like it. Looking forward to the next box.

Great Gift for a Science Kid!!!

My son thinks this is the best gift!!! He is 7 and has been able to perform all of the experiments himself. He gets so excited each month when this box comes.

We love these

My only problem with this box is we ordered 3 months worth and they came back to back for 3 months. We didn’t have time to finish the projects in each box before getting the next box. That being said now my daughter looks through all 3 boxes and picks what she wants to do. Our whole family enjoys doing the projects and my children really get into it. I hope they restock because I’d love to get 3 months worth for my niece.

I gave this as a gift to a 6 and 9 year old to occupy them over the summer break, and they loved this! It was a huge hit. I would buy from this company again!

Extending Grandaughters Subscription

I ordered this subscription for my granddaughters 9 & 4 year olds. Not only did they look forward to the box showing up each month they and their parents had a great time doing the experiments. Even the 4 year old could participate. In this case it is a good father daughter bonding time. They want me to order it again.

Put more quality into your family quality time

the perfect item for the child who loves to explore and learn, a hands on experience that will bring quality time, with a sense of pride and accomplishment. these items pick up where a lot of science and exploration classes end, giving the child / young adult room to grow, learn and let their mind be creative. I got the 6 month subscription because I wasn't 100% sure about the product, and the product is not cheap; Now I wish I would of purchased the longest subscription possible because they end up being a great value. If your quality time with a a child has come to be T.V. night or Gaming you owe it to your self and the child to invest in this product as it will boost the quality of your time together.

My niece was so excited to try out her experiments!

Fast shipping. Thank you!

Love the thought that went into this kit!

Purchased this for my son's 8th birthday and he loves it. We are also homeschoolers and if you are looking for something educational to add to your curriculum these kits would be a great choice! Everything is included. Great communication from the seller.

Will order again.

What a great science curriculum resource for homeschoolers!

My 8 year old son is loving the projects and I'm loving the organization, high quality printing, and clever use of materials. So cool--I would have loved getting these as a kid.

Great kit for teaching kids about STEM!

My kids had a great time with this set! (ages 8 and 11). It was nice to find a kit where they could build using electronics and learn about circuits in a unique, age appropriate way. They especially loved the squishy circuits and the wire loop game. It comes with instructions as well as an explanation of the science concept behind the activity. I also like that it included a science experiment they could do outside. I had as much fun as they did. My boys are looking forward to getting their next box.
