2. Research Question
What geologic feature are yardangs usually formed on?
Why is your science question important?
Our science question is important because it would help scientists with their experiments and provide a knowledge base for yardangs.
Why is your science question interesting?
Our science question is interesting because it could help scientist have an idea of where to land if they send a rover to mars.
Please add more specific details to the “important” statement, examples of how they might use the knowledge they gain would be helpful in clarifying your rationale.

3. Background Information
Yardangs are formed by loose sediment that is picked up by gusts of wind. If the wind is prolonged then the sediment wears down upon the surface. If the lines cut into the surface are all one direction then you can tell that the wind was very strong and blew in one direction for a very long time. However if there is a confused pattern of wind, then you will sometimes see large bald spots in between patches of yardangs.
Please visually organize this slide to help the audience make sense of the words on the screen.
Show the process.

5. Background Information
Yardangs are very variable and come in lots of different sizes. They can range from only a few centimeters to several meters long. Also, they can be as much as 30 meters tall. On Earth we can find the remnants of yardangs that were made long ago. Most of these remnants can be found in places like Egypt and Afghanistan.

6. Hypothesis Fox’s hypothesis: Doug’s hypothesis:
If there are many samples of yardangs then by looking at pictures of said yardangs then most of them will be in canyons. Because canyons would channel the wind through itself and loose sediment could be easily picked up and scraped across the canyon floor.
Doug’s hypothesis:
If there are many samples of yardangs then by looking at pictures of yardangs most of them will be found on mountains. Because at the higher elevations, wind is much fiercer and landslides would provide the required sediment.
Any other group members have their hypothesis? Every member must be represented here

8. Methods Spacecraft NASA’s Mars Odyssey Camera THEMIS Camera Image Type
Visible Images – to see details within the crater
MOLA – to see context of image and depth
Geologic Features Studied
Wind and dust, Yardangs, and on what geological features are Yardangs commonly found on?
Geographic regions we focused on
We would mostly study the central part of Mars.
Why would you only select the central part of Mars? Do you mean a certain latitude range or longitude range, or both? Define center.

Misc. Data – To record any other interesting information not warranted by our necessary data categories but certainly important to our study
Geologic Features --
Measurements
Picture Diameter – Rough estimation relative to image parameters based on THEMIS Camera’s Visible Image range of 18km x 30km
Categories of Data are incomplete
Missing the WHY – why must these categories of data be collected? What information will you extract from them?

Even by looking at this chart you can see most yardangs are near craters.

23. Our location points show most of the yardangs are found in the central part of
Mars.

24. Our graph shows that the most common geologic features were craters.
Followed by … give more details as some categories could be classified together, or show a pattern between features.
