1. CELESTIAL BODIES IN THE UNIVERSE

When you look at the sky at night you can see lots of bright objects.

They are celestial bodies. The universe consists of celestial bodies.

We can distinguish two types of celestial bodies:

- Celestial bodies that emit light and illuminate: stars

- Celestial bodies that do not emit light, but do illuminate: planets,

satellites, etc…  

Number 1 is a celestial body that does not give off light but does illuminate.

Number 2 is a celestial body that emits light and do illuminate.

3. Now, write sentences about the pictures. Look at the example.  

5. Complete the text with the following words. Then listen and check. 2

Stars are celestial bodies that emit their own light. For this reason, they can illuminate other celestial bodies.

Stars are very large but they appear very small to us.Stars are very far away from the Earth.Stars form groups called galaxies.

Some groups of stars form figures. We call them constellations. We can see some of these constellations at night.

9. Say how a planet is different from a star. Discuss your answers in groups and share your conclusions with the rest of the class.

Planets are celestial bodies without their own light. Planets receive light from the stars. They reflect this light.

An orbit is the path that a planet follows when they move around stars.

Satellites orbit around a planet and planets orbits around stars.

   

10. What is an orbit? Imagine a planet and draw its orbit.  

11. Say how a planet is different from a satellite. Discuss your answers in groups and share your conclusions with the rest of the class.

23. In pairs, order the following words and read the information about the moon.  

The moon is a natural satellite that orbits around the Earth.The moon reflects the light from the Sun.We can see the Moon during the day and during night, but we can see it better at night.

24. Listen and complete with the words in the box. 9

Like all planets in the Solar System, the Earth orbits around the Sun. The Earth takes 365 days (1 year) to orbit around the Sun.This movement causes the four seasons:• Spring: it starts on March 21 and ends on June 21.• Summer: it starts on June 21and ends on September 23.• Autumn: it starts on September 23 and ends on December 21.• Winter: it starts on December 21 and ends on March 21.When the Earth rotates on itself, the movement is called rotation. The Earth takes 24 hours to rotate itself. This movement causes us to have day and night.

31. Can you complete the text? Talk withyour partner and complete the text.

Sometimes during their orbits… the moon and the Earth form a line with the Sun. When this happens, an eclipse occurs.There are two kinds of eclipse: lunar and solar.A Solar Eclipse occurs when …the moon goes in front of the sun and blocks most of the sun’s light from the earth.During a total eclipse all you can see from earth is a ring of light around the moon which is part of the sun the moon did not cover.A lunar eclipse when ... the moon passes through the shadow of the earth. A lunar eclipse can last up to an hour and a half. During a lunar eclipse the moon may turn a reddish color.
