A seed is planted (crouch into a ball on the ground).
It’s spring now, the warm sun and rain make the seed grow into a sapling (slowly get taller & spread out arms).
In the warm summer breeze your big leaves sway, you feel strong with your roots deep in the ground (fingers open, arms stretched out and moving, stomp feet).
The days are getting cooler with the arrival of fall, leaves start to fall (fingers closed).
In the cold and darker winter, you feel sleepy (arms droop beside body).
