Each crate comes with everything needed to create a project as well as a TinkerZine with information and ideas for additional activities to go with the main project. I found the youtube video for putting the kit together very helpful!
Our first Crate was Electricity at Work with all the items needed to create your own motor.
The hardest part for Jayden was getting the coil tight around the disc. Otherwise he was able to do all of it on his own. We still did it together with Juli's help.
