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.
My son's box was missing an important piece to the air pressure car. As a result, he was unable to complete the project. He enjoyed the other two projects: Jelly marbles and Swinging Electromagnetic.
I'm so sorry your project was missing a piece. We strive for superior quality projects, but occasionally human error is bound to occur (happens to the best of us). Each STEM Discovery Box includes our contact information along with our SATISFACTION GUARANTEE. We went ahead and shipped you a new Pressure Powered Car so that your son can complete this awesome project. We apologize again for the missing piece, but please don't hesitate to reach out to us if you ever have a problem with your STEM Discovery Box. Thank you!
