#EducationWeek: Seeing is believing: Effectiveness of Facemasks. On this episode of #SpanningtheNeed, we will test different types of masks on the most effective materials to minimize the transmission with kids going back to school. It is time to prove what works and what doesn’t work. Joining us will be Mr. Ralf, “Science Guy” from OH WOW! Children’s Center for Science & Technology and Tim Styranec, a health and safety specialist at Youngstown State University. #spanningtheneed #masks #science
