Sandra: hello Pilar, we look forward to hearing you speak about everything you know. I would like to ask you some questions so that the children class knows a little more about the moon, the sun and earth. Pilar: of course, I hope I can help you. Sandra: first of all, we would like you to explain: what is the earth? Pilar: the earth is the planet where we live, it has a round shape like a ball and is made up of water and land. Sandra: and the sun, is it another planet? Pilar: no, it is not, the sun is a star that has its own light and heats the earth. That’s why the weather is warmer during the day because of the sun. Sandra: but, why is it only sunny for a while and the it goes away? Does the sun disappear? Pilar: no, it doesn’t. The sun never moves, it is the earth that rotates on itself lo, this movement is called rotation. Could you please help me with this? Thank you!
