So those 2 STEM Labs books looked pretty lonely on this site, and I went and made a 3rd one!
The difference here, is that this one isn't intended as a STEM resource. The projects in my STEM books are best for grades 3 and up, so this is for grades K-5. It's more for exploring key concepts in science, instead of focusing on building and accomplishing STEM tasks.
