With all the work I've been doing on 50 STEM Labs these days, I thought it was about time to expand the 50 STEM Labs Cards set!
I've added 9 more Projects, 9 more Rules, and 18 more Materials Cards. That brings the set from 63 cards to 99! Plus, you still get the 9 blanks of each card type.
That's a LOT more combinations of experiments!
