Welcome to Plum Landing.
Evaporation Station.
We're on a mission for Plum.
We want to show Plum what happens
after you paint with water.
I'm painting a cat.
All the stuff that we're painting with water
is evaporating.
It's a pretty sunny day.
Perfect for evaporation.
We've noticed as we paint on the ground
that it starts to evaporate in the sun.
Now it's been five minutes
and the fish is almost totally evaporated.
We painted some shapes with water and trace them with chalk.
Now when they evaporate,
it's easy to see the original shape we painted.
Water is a liquid and the sun turns it into water vapor,
which is a gas.
Then the water vapor goes up into the clouds,
and then from the clouds, it, like, rains back down.
I'm going to do an experiment
to show what happens when water evaporates.
I'm going to make a handprint on a piece of construction paper
and put that one in the sun.
And then I'm going to make another handprint
and put that in a plastic bag.
Now we're just going to wait to see what the sun does.
It's been about five minutes,
and the one that was just in the sun,
the water's just gone.
It's already been evaporated.
The one in the plastic bag,
I see little water droplets on the plastic bag.
It's almost as though the water vapor
has been caught in a net that's the plastic bag.
I'm comparing two different surfaces.
I'm going to paint water on metal and cement.
The metal feels warmer to me.
The water on the metal seemed to evaporate faster.
Maybe it's hotter.
I am painting a sun in the sun and a sun in the shade
and I'm going to see which one evaporates faster.
It's been about five minutes,
and the one in the sun is almost gone.
But the one in the shade is still as wet as ever.
Now it's been ten minutes,
and the one in the sun has now totally evaporated,
but the one in the shade is still trying to evaporate.
I think that the heat has something to do with this
because it's coolerin the shade,
and the one in the shade isn't evaporating as fast
as the one in the sun.
