Lesson 6 Ex.1a

Rain rain
falls on the street,
mud in puddles
cleaning my feet.

Thunder thunder
rumble and roar,
close the windows
and lock the door.

Clouds clouds
black and gray,
heavy with water
to drop all day.

Sun sun
is breaking through,
clouds are moving,
the rain stops too.

Rainbow rainbow
across the sky,
see-through colours
to tickle my eyes.

Host: Everyone talks about the weather and everyone's an expert, right? Today we'll see how good are our competitors' meteorological knowledge! Meet Ed and Jason.

Are you ready to start?

Ed and Jason: Yes!

Host: Question number one. What is the main cause of the earth's weather?.. And Ed was the first.

Ed: I think it's water! Its evaporation creates our planet's atmosphere.

Host: No! That's a wrong answer! Jason?

Jason: I believe it's the sun and its energy.

Host: Right! It's the sun and to be more exact it's the level of solar radiation that our planet gets. Question two. Why is the sky blue? And Jason was the first.

Jason: I know that the sunlight that comes to our planet is white, but it consists of a lot of different colours. Blue sunrays travel to the earth faster that why we see blue sky.

Host: Well, I think we can give you a point for your answer, Jason. The thing is that the molecules of air in our atmosphere reflect blue sunrays more than for example red or yellow ones. Our question number three is: Why does it start raining? Edward.

Ed: I think that's because of the water in the air.

Host: Water in the air? What do you mean.

Ed: Well, the air on our planet is damp since water exists in it in form of gas. But when this air cools the gas turns into water drops. As they become big and heavy enough they fall down from clouds, so it starts raining.

Host: You are absolutely right! And you get a point, Ed. Number four: since it starts raining when the air cools at what temperature does the rain turn into snow? And Ed was the first again.

Ed: When water drops turn into ice, it's about zero degrees Celsius or 32 Fahrenheit.

Host: Well-done, Ed! Let's move on to question five. What is dangerous lightning or thunder? And why?

Ed: Thunder.

Jason: Lightning.

Host: Jason, you were saying…

Jason: Lightning, of course. It can kill people for it carries electricity.

Host: That's true. Lightning kills an average of 50 people a year? Lightning can kill or injure you badly. Recovering from lightning strikes can take years. What's more lightning can hit people who are holding hands or sitting on one bench for example at a sporting event. Question six. What is “the eye” of a storm? And it's Ed now.

Ed: It's the central part of the storm. It's usually calm inside it.

Host: Good. And finally the last question. Why does a rainbow appear? It's Ed again.

Ed: It appears when the sunlight passes through very small water drops. They reflect light at different angles and we see different colours.

Host: Amazing! Looks like Ed is the leader of our game now and we go to the second round where…
