         Research Question

How large is the average crater size?
           Important Statement
• Why is it important
• -Our experiment is important
  because, if we research about
  craters and there average size, we
  can learn more about Mars, the
  atmosphere, and meteorites. If we
  find out more about Mars we
  could help scientists plan their
  trip to Mars and help them figure
  out how much protection we         http://www.psrd.ha
  would need or equipment to         waii.edu/WebImg/
  bring.                             Mars_craters.gif
              Hypothesis
• If we measure every crater we can find,
  then we think that the average crater size
  will be 18km, because 18km is the max
  size of the THEMIS images. In our
  studying of the THEMIS images most of
  the craters filled up the whole picture.
          Background Information
• The average height of a
  crater on Mars is Three
  Km.
• There are over 43,000
  craters on Mars with a
  diameter of over Five km.
• The largest crater on Mars
  was formed four billion
  years ago, and it was two-
  thirds the size of the moon.

Sample Size                                   150 THEMIS images used to gather data

Categories of Data to be collected and why?   Image ID#- Keep track of the specific image
                                              analyzed latitude/longitude keep track of

                                              Not warranted by our necessary data categories
                                              but certainly important to our studies.
Measurement                                   Rough Estimation relative to image parameters
                                              based on THEMIS camera’s visible image

MOLA Map of Mars
            Data Analysis
From the data we gather we found at the
  average crater size is 18km. Most of the
  craters in the THEMIS images were
  preserved and a lot had lava flows.
                          Conclusion
Q. What did your group learn fro the data you collected? Refer to your science
     investigation question.
A.   We learned that the average crater size is 18km. We got our answer from
     the data we collected.



Q. What would you do differently to make your investigation better? (Think
     about the data collected and the way you analyzed it, or the question you
     formulated)
A.   We should’ve been more accurate with our data.



Q. Explain what scientific questions could branch off of this study to further
     scientific research about Mars.
A. Some questions could be what is the strength of the soil and land if it could
     sustain greater impacts.
