Hello, I am Natalia. Hello, I am Sara. Hello, I am Alejandro.
00:00:00
And we are A Tortilla para Tres Personas.
00:00:05
A Tortilla para Tres Personas. Tres Personas. Tres Personas.
00:00:07
And we are going to talk about the water cycle.
00:00:14
The water cycle. Water is always moving around the Earth.
00:00:17
We call this movement the water cycle.
00:00:22
It takes between the atmosphere and the earth crust.
00:00:25
First stage, evaporation.
00:00:31
The sun heats liquid water.
00:00:33
It evaporates to form water vapor in the air.
00:00:35
Second stage, condensation.
00:00:39
When the water evaporates, it forms clouds.
00:00:42
It forms droplets.
00:00:47
And when there are droplets, it forms clouds.
00:00:48
Third stage, precipitation.
00:00:52
The tiny water droplets form large heavy drops. These droplets fall from the clouds as rain or snow onto the Earth's crust.
00:00:55
Fourth stage, collection. Water in the rivers goes into the seas and oceans. The cycle starts again.
00:01:07
Questions!
00:01:15
First question. What is the name of the instrument that measures the precipitation?
00:01:17
You have 10 seconds.
00:01:22
Second question, what is the stage of evaporation, and you have 10 seconds.
00:01:23
It's when the sun heats liquid water and it evaporates to form water vapor.
00:02:00
Well done!
00:02:06
Third question, what is the cycle of the water cycle?
00:02:07
You have 10 seconds. And the answer is, first stage is evaporation. So the water evaporates. Second stage, condensation. When the water condensates, it forms clouds.
00:02:12
Third stage, precipitation, is when the clouds form heavier drops and it rains. And collection is when it rains and it goes to season.
00:02:42
Well done. Thank you for listening.
00:03:00
Hello, my name is Sara. Hello, my name is Natalia. And we are going to present our water cycle experiment.
00:03:06
The ingredients are a little glass, a transparent glass, some ice cubes, some hot water, some salt, and two film papers.
00:03:29
First, we pour in the bowl the hot water, then we put some salt and we mix it up.
00:03:43
Then we need to put the little glass in the bowl, then we need to put the filling paper
00:04:03
on the transparent bowl and we put another. Then we put the ice cubes on the filling paper.
00:04:12
Now we are going to wait ten minutes. They have passed five minutes and like you see
00:04:56
in the bowl there is water vapor. And we keep waiting. They have passed ten minutes and
00:05:03
We are going to put off the cubes of ice and the paper film.
00:05:12
We are going to put off the paper film with glue.
00:05:27
Now we are putting off the little glass and now we are going to see the result.
00:05:38
Do you see?
00:05:46
this is the end of the water cycle experiment thank you
