As children we were often asked what we wanted to be when we grew up.  Sometimes, the careers we picked did not turn out to be what we ended up doing in adulthood; and other times, we made selections not fully knowing what was available to us.  This week's author, Tiffani Teachey, wants to make sure that no child has to ever wonder what they can do with their love of science, technology, engineering, and math (STEM).  As a Sr. Mechanical Engineer, Tiffani crafter her book, What Can I Be? STEM Careers from A to Z as a guide for the youngest readers so that they can envision STEM careers here on Earth and even among the stars.
