SCIENCE OF EVERYDAY LIFE - 3M has partnered with Discovery Education to bring this resource in the hands of K - 12. There are interactive videos & labs and inquiry-based lessons aligned to national standards by grade level. The idea is to help kids relate to the science they experience everyday and understand it better.
