In the Body Functions work, children use nomenclature cards to explore how the heart evolves across vertebrates:
- In fish, a single flow keeps life moving.
- In amphibians, two worlds begin to meet.
- In reptiles, pathways grow clearer.
- In birds and mammals, four chambers create perfect harmony.
These cards do more than name parts and functions. They help children build precise language, see patterns in nature, and connect details to a bigger story – a story of evolution and interdependence.
And perhaps our own hearts follow a similar journey: from caring for ourselves, to opening imperfectly to others, to finding clarity, until one day, we beat for all of life.
