I believe Follett has some pre-made kits that you can purchase if you happen to use them as a vendor.  I don't know what your budget is or how you can place orders, but you can probably create your own as well.  When we had makerspace at our school, they had some time of circuitry activities, painting, and computer coding type stations.  You can also use legos or ask if there options within your school to collaborate with Home Economics teachers (woodworking, shop, etc.).  A good person to contact is Melissa Thom in West Hartford (Bristow) http://blog.whps.org/bristowlibrarylearningcommons/.  I know she is doing lots of good stuff...Good luck!
