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.

Objects fall from space How Mars’ Craters are formed It starts to speed Up and burn It enters the Atmosphere of Mars With the high level of Speed, it impacts the Ground making a big hole

Methods used CameraThermal Emissions Imaging System (THEMIS) SpacecraftMars Odyssey Image typeVisible 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.

Methods used (continued) Sample sizeAt 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. Methods Methods used

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
