The Grasshoppers looked at physical activity and the effects it has on their bodies.
The children started by listening to their resting heartbeats though a stethoscope.
Then they took part in some physical activity.
Such as jumping, running and dancing.
Once they had done this they listened to their heartbeats through a stethoscope.
Comparing the difference between a resting heart and a heart after physical activity.
The children noticed it was much faster.
They used drums to tap out the heart beat with the beaters.
Paying attention to when they could feel their heart beating in their chest.
The children laid down to calm their breathing and paid attention to breathing in and out.
