ACTIVITY: What will you find if you dig ahole, as deep<br />
as it can go?<br />
Look at the picture of adigging machine <strong>and</strong> imagine you are<br />
driving it.<br />
Teacher's Note<br />
Imagine that you have a powerful digging machine<br />
The purpose of this drawing task is to make learners grapple with<br />
the idea that they are on aball-shaped Earth. Most learners have<br />
no problem with saying that the Earth is shaped like a ball <strong>and</strong><br />
most have seen pictures of the ball-shaped Earth like Figure 1. But<br />
this concept is not easy to think with, when you are actually<br />
st<strong>and</strong>ing on the ball. So the question, "what would you find if you<br />
could dig ahole right through the ball?", makes them move<br />
mentally between the ground they can see <strong>and</strong> the view of the<br />
ball-shaped Earth as seen from Space.<br />
