3. Was it daytime in Saudi Arabia? Hint: Use your globe to find Saudi Arabia and then find it in Picture A to see if it is day or night. Yes, there is sunshine on Saudi Arabia. 4. Was it day time in Argentina when this photograph was taken? Use the globe to help you locate Argentina. Explain your answer. No, it was night time in Argentina; in the photo, Argentina is on the darkened side of the Earth, and there are lights showing. 5. The tip of Brazil is in the sun in Picture A. Is it morning or afternoon in Brazil? Why? It is morning, because Argentina is moving towards the east and into the part of the Earth that is in the light. Picture B 1. Look at Picture B. What part of the Earth is this picture showing? Europe and the top of Africa. 2. Can you see the lights on in Italy? When it is dark in Italy, is it still light in Spain? Yes 3. Is it late afternoon or morning in Spain in Picture B? It is late afternoon. Now that we have looked at some photographs of the Earth as it changes from day into night as the Earth rotates, let's make a model of Earth using our heads to explain this. ACTIVITY: Your head can be amodel of the Earth MATERIALS: • yourself • sunlight coming from one side INSTRUCTIONS: 1. This model will help you to understand why we see the Sun move across the sky. Do this in the early morning when the Sun is still low. 74 Earth and Beyond
2. We will say that your nose is Africa. You are on Africa. Look at picture below. Using your head as a model of the Earth. 1. Now stand so that bright light from the Sun shines across your right cheek. 2. Turn slowly to your left. Turn your eyes towards the bright place where the Sun is. You will see the Sun move to your right while you move to the left. 3. Move your feet and turn further; you will see the Sun "go down" over your right cheek. Teacher's Note They must move their whole bodies round, not just their heads! 4. When you have turned your back to the Sun, you cannot see the bright light any more. That is like night-time in Africa. 5. Turn further to your left and you will see the Sun "rise" over your left cheek. That is like sunrise in Africa. Chapter 1. Planet Earth 75
