Per student or team of 2-4 students
Image of Mars - either printed out or viewed on the Internet (available at Mars Exploration Rover Mission site)
Note: This image will also be used for another activity in RoverQuest.
Clear overlay that has at least 1" grid so students can identify features using a quadrant system. The image itself can also be produced to have a grid.
Magnifying glasses if available

This activity will place students in the role of scientists as they use observational and critical thinking skills to analyze and hypothesize about an image of Mars. Students will determine what they think to be scientifically interesting by making visual observations and rank their observations in order of importance.
This activity follows along with the way Mars scientists look at images from a lander on Mars. As they study an image, they look at even very smallest details to try to learn about the history of that area on Mars.
| 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. Each day, rovers will send to Earth new images that the science team must examine. These images will allow the scientists to think of hypothesis that relate to help the science team decide what to study and determine what experiments they will conduct. |
- After the students choose what type of scientist they desire to represent, have them gather in working groups. These groups can either be a mix of different disciplines or the same disciplines.
- Have the students observe an image of Mars (current images available on the Mars Program homepage- see URL listed under materials) and make observations on their student worksheet as to what they can see within the image.
- Have the students prioritize their observations as to what they think is scientifically Interesting using the grid system (e.g. small rock - I,74).
- Have the students form hypothesis as to what they are seeing. For instance, what is the story of why it looks like it does? Have them evaluate if they have enough information to form a hypothesis. If not, what is missing?
- Have the students think of ways these hypothesis might be tested (e.g. further observations, using instruments on the rover, etc.)
Students can be assessed on the completion of the Greetings from Gusev worksheet, participation in group or class discussions and/or a presentation of their observations of the Spirit landing site.

ADAPTATIONS / EXTENSIONS:
- Overhead transparency of image so you could conduct this lesson with the entire class
- Compare the Mars Pathfinder Landing site in Ares Vallis to that of the Spirit Lander in Gusev Crater. Image can be found at: http://mars.nasa.gov/MPF/ames/ames-pres.html
- Look at areas on Earth that would be analogs to what we are seeing on Mars (e.g. Antarctic dry valleys, summit of Mauna Kea volcano in Hawaii)
