This is what cows eat.
It's grass.
It's what we walk on.
It's the ground.
Where cows eat grass.
It's a field.
Birds build this for their eggs.
It's a nest.
It's a small river.
It's a stream.
You have this near your tent. You use it for cooking.
It's a campfire.
It's the place where we all live.
It's the world.
A special thing in the sky at night.
It's a shooting star.
These fall from the trees in autumn.
They're leaves.
The part of a tree with leaves on.
It's a branch.
