Students volunteering to stay after school for additional work? That is what is happening at Hedke and Anderson. Each school is hosting an after-school Science, Technology, Engineering and Math (STEM) module lasting several weeks. The student interest was so great that both programs are completely full. The class, taught by Hedke 5th grade teacher Mr. Cihak, consists of 20-22 3rd and 4th graders who voluntarily enrolled in the program. The class is based around the science of space exploration.
