Karen Murphy, who is principal at Free Orchards Elementary School where I work, is a champion of trauma awareness and is working hard to lead our school in the direction of trauma sensitive practices -and away from the policies & procedures that have historically made well-intentioned school districts part of the "pipeline to prison". One of her sayings is "fix yer face", which means simply to put a warm expression on your face, consciously and regularly.

This year I came up with an effective strategy using an app on my iPhone. I have been working with 3-6 graders showing them how their heart rate tells a story about how they are feeling in response to external stimuli. I show them through a series of three experiments which measure their heart rate under three different circumstances.
