All of the other packs have arrived, and this was the last to make it! With this, all 7 planned STEM Holiday Expansion packs have been released.
With all of these new projects, I'm just around 8 projects from a 2nd volume of STEM Holiday projects! Is 50 More Holiday STEM Labs on the way?
Author of 50 STEM Labs Series, as well as over 100 educational volumes and 20 novels!
