2 Surface of the Earth 84 KEY QUESTIONS • What would you find if you could dig avery deep hole? • Where does soil come from? • If you were going to buy a farm, what kind of soil would you look for? Teacher's Note Chapter 2 deals with the rocky crust of the Earth; we aim to teach the children where soil comes from: soil is broken-down rock plus organic matter from plants and animals. However, we can't just teach about the crust because that would leave a hanging question – the crust of what? So we spend alittle time looking at what the crust is covering, and so we look at the structure of the Earth. 2.1 Rocks QUESTIONS 1. You saw the photo of the Earth at the beginning of Chapter 1. What is on the surface of the Earth? Name all the features (parts) you can think of. Answers may include Land, sea, forests, rivers, deserts, air, clouds. Learners may correctly include animals and people though they cannot see them in the picture. 2. What do you think is under the surface? Answers may include soil, rocks, mines, bones, roots, drainpipes, and many more. Encourage them to think of as many ideas as they can .
ACTIVITY: What will you find if you dig ahole, as deep as it can go? Look at the picture of adigging machine and imagine you are driving it. Teacher's Note Imagine that you have a powerful digging machine The purpose of this drawing task is to make learners grapple with the idea that they are on aball-shaped Earth. Most learners have no problem with saying that the Earth is shaped like a ball and most have seen pictures of the ball-shaped Earth like Figure 1. But this concept is not easy to think with, when you are actually standing on the ball. So the question, "what would you find if you could dig ahole right through the ball?", makes them move mentally between the ground they can see and the view of the ball-shaped Earth as seen from Space.
