All last year, we spoke about how in the Fall the leaves turn colors and fall to the ground. We spoke about how then during the winter the trees are bare and only have branches.
Now that it is spring, we have been talking about how the leaves sprout from the tree branches.
She's not buying it.
She says this is how the leaves get onto the branches (aka sticks).
The bumble bees drink nectar from the flowers that grow in the spring. Their feet get sticky and they use their feet to glue the leaves back onto the tree sticks.
It's a good hypothesis for a 3.5 year old.
