1. Do objects look different as you look at them from different distances? Explain.

2. Elevation is the distance above the surface of the Earth. Altitude: the distance above sea level Resolution: The eyes ability to see that two tiny objects are separate.

3. Elevation Human Made Structures Natural Structures 100 m above Earth (p. 4) (neighborhood) 1000 m Above Earth (p. 5) (community) 10,000 m above Earth (p. 6) (area) 100,000 m above Earth (p. 7) (region) 1,000,000 m above Earth (p. 13) (Continent) 10,000,000 m above Earth (p.14) (planet) Bridges, city lights boats Houses, cars school, roads Houses, cars boats, highways none Trees, grass Greenery, water, mountains Water, mountains Water, mountains, Land, craters Water, land, ice clouds

4. Conclusion How does elevation affect how you see human made structures and natural structures? What changes are happening? How does elevation affect how you see human made structures and natural structures? What changes are happening?

5. Conclusion As you begin to elevate, the human structures get smaller and smaller until you cannot see them and the natural structures got larger and you can see more of them. As you begin to elevate, the human structures get smaller and smaller until you cannot see them and the natural structures got larger and you can see more of them.

6. Powers of 10 Each successive image of Earth, starting with the map you made, represents the view from an observation platform ten times farther away that than the previous platform. Structures on Earths surface in the neighborhood view look ten times larger than the same structures in the community view. And structures in the community view look ten times larger than the same structures in the area view. Consequently, structures in the neighborhood view look 100 times larger than the same structures in the area view.

7. Billy was watching his favorite TV show when the question came up, Where do you live? Billy didn't know, so he asked his older sister the same question. She replied, In Birmingham. Later Billy asked his mom the same question, to which she replied, Honey, you live in North America. Billy was a little confused. He thought, How can I live in two places at the same time? Who was right, Billys sister? Billys mom? Explain your answer.
