Why is your science question
important and interesting?
• Our science question is important because someday
humans could live on Mars, and we would like to
know if craters are dangerous so we could stay away
from them if we had to, scientists would also like to
learn more about Mars this way.
• Our science question is interesting in some ways
because we don’t actually know what is inside Mars’
craters and that makes us curious about finding out
what is inside Mars’ Craters.
Hypothesis
• Some people predict that there might be different
kinds of gases that inside the craters that are
dangerous to humans
• Others think there could be different types of rocks
inside.
• 7 people say we will see liquids inside the craters.
• One person thinks they will see rocks inside the
crater.
• Three people predict they will see magma, and one
person thinks they will see dunes inside the crater.

If we analyze images of Mars, then we should see ice particles
because Mars is too cold for gases to stay gases ,
If we look for rocks inside the craters, then we should see lots of
rock fragments because rocks are usually in fragments.
If we look for liquids in the craters, then we should look for gases
because it is too cold to stay in liquid form.
If we look for sand dunes in the craters, then we should find
ripples in the sand because sand dunes often come as ripples in
the sand
If we explore pictures for evidence of magma, then we should find
old lava tubes because it is too cold on the surface of Mars to have
hot magma.
Background Information
• A crater is a hole in the ground that is formed by impact of something
from space.
• The difference between Earth’s atmosphere and Mars’ atmosphere is that
when something enters Earth’s atmosphere, it starts to burn up because
of friction and then it keeps burning until there is nothing left or it has hit
the ground.
• This is to protect Earth and its inhabitants from any danger of outer space.
How Mars’ Craters are formed
Objects fall from space
It enters the
Atmosphere of Mars
It starts to speed
Up and burn
With the high level of
Speed, it impacts the
Ground making a big hole
Methods used
Camera
Thermal Emissions Imaging
System (THEMIS)
Spacecraft
Mars Odyssey
Image type
Visible images to see details within
the image
MOLA- to see context of image
and depth
Methods Continued.
Geologic
Features
studied
Craters and the surrounding
area(s)
Geographic
regions we
focused on
All of Mars that have craters, and
the inside of Mars’ craters.

used
Methods
used (continued)
Sample size
At least 150 THEMIS images
(10 pics each)
Categories of
data to be
collected and
why?
THEMIS Image ID# - to keep the specific image
analyzed
Latitude/longitude - to keep exact locations and
their proximity
Misc Data - to record any other interesting
information about Mars that isn’t warranted
Inside the craters - because that is what are entire
PowerPoint is about.
Conclusion
Our research question was “what is inside Mars’ craters” We answered this
question with lots of experiments and looking at pictures of craters.
The hypothesis of gases being inside the craters were proven incorrect,
because there were no frozen ice particles of any kind
The hypothesis of rocks being inside the craters were correct, because rocks
erode and they fall down hill to inside the crater
The hypothesis of seeing liquids was wrong because there was no ice particles
of any kind that were seen
The hypothesis of seeing magma was wrong because there is no magma or
evidence of magma currently there, but evidence of magma that used to
be there
The hypothesis of sand dunes inside the craters were unknown because none
of us saw any sand dunes or anything like it
