An acorn is the seed of an oak tree. These trees have
a little extra help in spreading their seeds. When
oak trees drop their acorns in the fall, many of them
are gathered by squirrels for food. The squirrels
bury some of the acorns in the ground to save for
a later time. In the springtime, some of the acorns
that have not been uncovered sprout and begin growing
into new oak trees!
