STEM may be a new concept in early childhood, but it's an approach that Fred Rogers used all through his television series. Let's explore what he did and use his approach in a developmentally-appropriate way to introduce children to STEM concepts -- in a way that makes teachers more comfortable with subjects like science, technology, engineering and math -- and also helps make the children's learning more meaningful. Then we'll find ways to help children build on those STEM experiences using discussions, scientific inquiry, hands-on activities, literacy, and the arts.
