This model investigation is going to focus on hurricanes....

1. RESEARCH QUESTION:
How does the eye of a hurricane change as the strength of a hurricane increases?

2. SOURCES TO VIEW ASTRONAUT PHOTOS:
1) http://ares.jsc.nasa.gov/ares/eeab/atmosphere.cfm (look at "hurricane" tab)
2) http://eol.jsc.nasa.gov/sseop/EFS (click on "Hurricanes & Weather" and then scroll down to "HURRICANE")
3) http://eol.jsc.nasa.gov/sseop/technical.htm (in the "Features Contains" box on the left side of the Technical Search boxes, type in "Hurricane"

3. LIST OF SPECIFIC DATA TEAM WILL LOG FROM EACH ASTRONAUT PHOTO:
1) Image Identification #
2) Hurricane name
3) Hurricane strength
4) Hurricane location
5) Date of image
6)"Eye" State: Open or closed
7) "Eye" Shape: Circular, irregular
8) "Eye" Definition: Well defined, somewhat defined, or not well defined
9) Sketches of "eye"
10) Miscellaneous notes or observations

(Note: As you think of what specific data you will log, try to include choices of characteristics you will look to observe. For example, in #6, you would log whether the eye is open or closed. This will allow you to later sort your data by the "eye state" so you can look for patterns. The same is true for #7 and #8 listed above. If you do not provide choices for shape, and all team members list completely different shapes of eye definitions, it will be more challenging to look for patterns.)

4. HYPOTHESIS:
Based on the observations we have made of hurricanes that have come through our area, we hypothesize that the stronger the hurricane, the more defined the eye will be. The more defined the eye is, we believe this will cause the eye to be more circular. We also believe stronger hurricanes will have "open" eyes. We believe this because we compare water going down a drain to hurricane. The stronger the water is draining, the more visible and open the center area.

(Note: A hypothesis should be supported by some evidence...it is not just a guess.)
