10/19/11 B DayLEQ: How do humans use technology to study geologic evolution?1. What is an adaptation?2. What is one adaptation that bald eagles have to help them survive?3. What is natural selection?4. Give one example of natural selection. 5. Copy and complete the following sentence:
If two species share similar adaptations, we can assume that they (share a common ancestor/ were
born on the same continent)

Today’s LEQ: How do humans use technology to study geologic evolution?
By the end of today, you should be able to…
1. Compare and contrast information gathered from remote imagery and ground truthing
2. Identify the different ways that sets of data are collected
Focus Vocabulary:
42. Remote Sensing43. Ground truthing44. Urban Sprawl
Activating Strategy:
Discovery Education: Tragedy in New Orleans
STOP AND JOT:How did scientists, politicians, and
the media collect information about the causes and effects of
Hurricane Katrina?

What information can you observe and infer from this photo?
What information can you observe and infer from this photo?
How are these two photos different?
You just discovered….
The two different methods for collecting
data about geologic evolution!
Draw this in your notes:
Collecting Data
REMOTE SENSING:-collecting information about an area without visiting it
Ex. Satellite photos
Image 2Image 1
Observe and Infer: Let’s compare these two regions…
How can remote sensing help us see…
–Beach erosion (evens)–Deforestation–Forest Fire damage–Volcanic eruptions (odds)–Urban Sprawl–Ice on Earth
B. We can see beach erosion after a hurricane through satellite imagery (remote sensing)
Deforestation
Forest Fires!

Remote Sensing ???????

Collecting Data
REMOTE SENSING:-collecting information about an area without visiting it
Ex. Satellite photos
GROUND TRUTHING:-collecting information about an area by visiting it
Ex. Taking water samples

What are the advantages and disadvantages of using remote sensing?
Advantages• Can track changes
of an area over time• Do not actually have
to go to the area• Can collect data
from the area anytime
Disadvantages• Cannot test
conditions of the environment
• Cannot see detail• Cannot talk to
people who are there
What are the advantages and disadvantages of ground truthing?
Advantages• Test the conditions of
the environment• More detail regarding
the area can be observed
• Verify what remote sensing gathers
• Talk to people who are there
Disadvantages• Can only survey a
small area at a time• Cannot track change
of the area over a long period of time
• Can only collect data when area is safe
HOT Q: Think-Pair-Share It’s 2005, and Hurricane Katrina is hitting
New Orleans. How could you use remote sensing and ground truthing to gather data and information about the hurricane and the damage it caused?
CONTEXT CLUES:1. I live in an urban area. There are big buildings,
busy streets, and lots of people that always seem to be busy!
2. He was so tired from school that he went straight home and fell asleep. When his mom got home, she found him sprawled across the couch with his backpack still on!
2. Her things were sprawled all across the floor. You could barely see the carpet when you walked into her room!
Stop and Jot: Write your own definition of these words!
Word Study:Urban = City
Sprawl = spread out; usually in a sloppy way
WHAT IS URBAN SPRAWL?

SUMMARIZER: Write a letter to the mayor of Charlotte!Your letter should:1) Describe urban sprawl2) Explain how we study urban sprawl (how do we collect the data?!)
3) Describe the negative effects of urban sprawl4) Give 2 ways that we can alleviate (ease or fix) the problem
of urban sprawl in Charlotte
