Sample Apple Graphs
Graph Borrowed from Population Connection Presentation.
Directions:
- Cut Whole Apple into Quarters
- 3/4 represents the portion of earth covered with water- Set these aside.
- 1/4 represents the portion of land on earth
- Cut 1/4 in half. One of the pieces which equals 1/8 of the whole apple represents the areas where people can't live: the polar areas, deserts, swamps, and very high or rocky mountains.Put it aside.
- Cut the second piece, also representing 1/8 of the whole apple, into 4 sections. Hold 3 of these pieces in one hand and hold up the single section and ask the class, What does this section represent? 1/32
- These 3/32 represent areas of the earth that are too rocky, too wet, too cold, or too steep. the other portion of this 3/32 represents land with a low soil quality. These sections also contain highways, neighborhoods, communities, and cities. Put these 3 pieces aside.
- Take the remaining 1/32 and peel this slice. The skin of this 1/32 represents the amount of fertile land on earth. This very thin layer represents the very thin layer of Earth that we can grow food in. It is less then 5 feet deep. It takes 100 years for 1 inch of topsoil to be replenished.
