🫀 Heartbeat Expo Presentation

Small groups present their Heartbeat Expo investigation poster, class poster sections, and selected journal evidence to families, the gym teacher, and another second grade class. Students demonstrate one safe movement, show how they counted pulse and breaths before and after exercise, and explain what their charts and drawings show about the heart, lungs, and muscles. Visitors ask questions, and students answer using numbers, labels, and observation language from the investigation.
