GIRL: Eric, Grace, Grace's mom and I
are going into the woods.
We found a stream.
Grace is trying to put a leaf in the water.
Let's see if it goes down.
It's going really fast.
It's still going.
See, it's over there.
GIRL: See, it got stuck
on a branch.
I have a piece of bark and a piece of leaf.
Maybe that could be a sail or something.
GIRL: It sunk.
A piece of bark.
I think it might get stuck, actually.
GIRL: Get stuck,
and then sink.
It's down here, can you see?
It's under the water.
Turn on the water.
GIRL: We went home, and Grace's mother turned on the hose.
GIRL: Hey, Caroline, Eric,
I made a stream.
I'll try this.
CAROLINE: We were putting leaves
and flowers into the stream.
Flowers.
CAROLINE: The flower is going down really fast.
GRACE: I think it went down fast
maybe because the petals went out,
and the water kind of caught the petals and pushed it down.
CAROLINE: Try putting things in a stream to see how they move.
