Student Worksheet

**[Background]{.underline}:** How do scientists look at images that are
sent back from another planet and determine what is interesting and
needs further investigation? Mars rover scientists do this very task
during surface mission operations. As each image is received back on
Earth, scientists think about and discuss the different processes that
could make Mars look the way it does. Next, they try to form a
hypothesis or a set of hypotheses as to why things look like they do in
the image. Finally, the science team forms a plan as to what to study
within the image and determine what experiments they will conduct to
help test their hypothesis.

[Real World Application]{.underline}: The Mars Exploration Rovers are
robotic geologists sent to the surface of Mars to determine the history
of climate and water at a site on Mars. The Opportunity rover has a
camera (Panoramic Camera or Pancam) that has taken a 360° picture of
where it landed - inside Gusev Crater on Mars. From these pictures,
commands are sent from Earth to Mars allowing the rover to conduct
scientific studies and the data is returned to Earth for scientists to
analyze.

**[Instructions]{.underline}:**  Imagine that you are one of the Mars
rover scientists listed below.  Your job is to study an image of the
Gusev Crater landing site on Mars and see how much you can learn about
this site using visual inspection.  Be sure to look for even the
smallest details in this image. As you answer the questions below, think
about the way this site looks and what processes may have made it look
this way.  

**Categories of scientists that study Mars -- disciplines they
represent:**

Astrobiology -- looks for life or signs of life on Mars

Atmospheric Scientist -- studies the atmosphere surrounding Mars

Geochemistry -- studies the chemistry of the rocks on Mars

Geophysicist -- studies the interior of Mars

Meteorology -- studies the weather on Mars

Mineralogist -- studies the minerals on Mars

Planetary geology -- studies the geology (rocks) of Mars

1.  Which type of Mars scientist are you?

2.  What interest you in this type of science?

3.  Based on your observations of this image, identify any features
    (like rocks, hills, soils, sky, etc.) you can see in the image. Make
    a list of these items, listing the number of the grid the feature is
    found in. Use the back of this sheet if necessary.

> a\. Grid \# Feature:
>
> b\. Grid \# Feature:
>
> c\. Grid \# Feature:
>
> d\. Grid \# Feature:
>
> e\. Grid \# Feature:
>
> f\. Grid \# Feature:

4.  Choose the top 4 features that you think are the most interesting
    (for any reason). List them the order with number 1) being the most
    interesting.

> 1\) Grid \# Feature:
>
> 2\) Grid \# Feature:

> 4\) Grid \# Feature:

5.  Choose the top 4 features in this image that you think are the most
    interesting scientifically.

> 1\) Grid \# Feature:

> 4\) Grid \# Feature:

6.  How do the list in question #4 and the list in question #5 compare?
    Are they the same? Why or why not

7.  Pick out one of the features you chose and write a description of
    what you are seeing. Describe it as well as you can, looking at all
    the details of this feature.

8.  Looking at this image, how do you think this feature was formed?

9.  Do you think you have enough information to create a hypothesis? If
    not, what other information would you need?
