Water on Mars

by: Kayleigh

My topic was about Mars. I chose this topic because I heard about another student in past years. Also, because it sounded interesting to me

My exact question was, was there once water on Mars? After I heard about the other students, I went home and thought about the topic. I decided to do that for my KIC project.

Mars is more than 140 million miles from the sun. Mars is 4,218 miles across One Martian year is 687 days One Martian day is 30 minutes longer than one earth day. Mars was named after the god of war because of its blood red color. Other people like Galileo, looked at Mars through some of the earliest telescopes.

To answer my question, I made observations on a dried stream and read some books on Mars The dried stream was near my house. Then I made observations on an erosion model by getting a plastic tub. Get some diatamaceous earth Pour the diatamaceous earth into the container Then pour some water into the tub and swish it around Next, tilt the tub to make sure all the water gets down to one side. Let it sit like that for five to ten minutes After that, compare your results to a picture in a book Later, I tried this experiment about six times Finally, I experimented and recorded my data.

I noticed that the erosion model looked almost exactly like the pictures of Mars in a book. I also watched the dried stream that looked like the picture in the book

Some suggestions I have for future students next year would be to continue my work. I wanted to try but didn't have enough time to take pictures of the river Another question someone might ask is, was there once life on Mars? This might be answered by doing my test over and finding new evidence.
