So it had to happen...
I took the 3 best-selling volumes of 50 STEM Labs and combined them into 1 handy volume. After thousands of downloads and copies sold, it just seemed like it was time.
You can still get the original 3 volumes, but in this one, I've resorted the 150 STEM Labs into 12 handy categories. This is perfect for teachers that like to do a unit study. Get all of them at a fair discount from buying all 3 volumes, too!
Author of 50 STEM Labs Series, as well as over 100 educational volumes and 20 novels!
