In this step, it is important that you have a finalized research question and hypothesis/es. These items drive the methods/experiment design (listed below) for you to complete your research. It is important to keep these two aspects of your research in mind throughout your investigation.

B. FINAL HYPOTHESIS (Include a brief explanation of observations & other knowledge that support this hypothesis): A hypothesis should be based on observations you have already made as well as any other background knowledge you may have.

METHODS (Experiment Design):
RESEARCH CONSIDERATIONS:
1. Image Data Collection: Where will you retrieve your imagery/data?
This Investigation: This activity includes imagery and data for a variety of planetary worlds. Data/Imagery of Earth is Crew Earth Observation (CEO) Imagery; Data/Imagery of other planetary worlds includes a variety of data from remote sensing instruments on planetary spacecraft exploring these worlds.

2. Specific Data to Collect: What specific data will you collect?
This Investigation: The following information will be logged from each image: 1) Image Identification #; 2) Crater name (if known); 3) Latitude (N); 4) Longitude (E); 5) Planetary Body; 6) Geographic location (country or region)

Additional data that focus on visible observations include: 7) Crater diameter (km); 8) Crater Type (Simple or Complex) 9) Crater Classification (preserved, modified, destroyed); 10) Miscellaneous notes or observations; 11) Sketches.

3. Number of Images: How many images is enough for your study?
This Investigation: Log data for a minimum of 8 different craters from each planetary world you are investigating.

4. Geographic Regions: Will you focus on a particular region?
This Investigation: This investigation will not focus on any particular region.

5. Other Data Sets: Will you use other data sets as part of your investigation?
This Investigation: No additional data sets are required. Supplemental data, however, was retrieved from the Earth Impact Database.

6. Measurements: How will you make measurements?
This Investigation: Estimated measurements can be made based on scale bars/measurement lines provided on images.

7. Sources: What sources will allow others to retrieve the data you used (or find additional data)?
This Investigation: Images and data were retrieved from the following sites: Gateway to Astronaut Photography of Earth (http://eol.jsc.nasa.gov); Earth Impact Database (http://www.passc.net/EarthImpactDatabase/index.html); JPL Planetary Photojournal (http://photojournal.jpl.nasa.gov/).
