FINAL TASK.

A strong wind has come. Yu have seen a very bright light and then you have seen yourself in a very strange planet surrounded by aliens!!!!!!

Aliens explain to you that if you want to go back to the earth you should make them a very clear report about your planet. Have into account that if they don´t understand things properly you will never come back! These are the points you should include:

Where is your planet? Is it the only planet in the galaxy? Are there other planets there? Why is the Sun so important to your planet? Give information about the sun. Is there any satellite? What`s its name? Can you include a diagram about its phases? Is there always sunlight in your planet? Why? Why are there seasons?

Finally aliens seem to be happy with your report and you are safe home but now everybody wants to know about your extraterrestrial experience. So you go to a t.v show to answer some questions. You are going to prepare a sketch and you are going to aswer a journalist´s questions about your experiences!

Prepare some questions and answers about your experience. You should talk about aliens ( appearance and behaviour) and also about your planet in order to do so, you should select a planet from the solar system and you should have as much information about it as you can!
