As I was reading through the articles on a page, I came across one, read the title, and realized it was relating to something I had already written. The robot curiosity, was sent to Mars in August, to search for any organisms or signs of there being once a life. This robot seems to have landed right in the middle of a former stream. Having found evidence of water is no surprise, it has been found already, however how the water got there is still unclear, could there have been ice? canyon?

“Curiosity had been analyzing nearby rocks. These supplied the new evidence that water once flowed through the crater. The rover found rocks called conglomerates, which form when pebbles and sand get stuck together with wet sediment. That sediment is the solid material that settles at the bottom of a river or stream. Curiosity has found conglomerates at two sites so far. At the second site, the conglomerate rocks were about the size of plain M&M’s.”

It is impressive that Curiosity has already found this evidence in such time, however this is only the beginning, hopefully more evidence might come up.

I didn’t find this article special or anything, I just thought it would be cool to read what curiosity had found.

Water Magic

You are hurrying to school on your bike, and suddenly your homework falls out of your backpack. Last night was raining so there are puddles everywhere. OH NO! You drop your bike, try to save your paper but you're too late, your paper has colors where your writing was, now you will have to think of an excuse.

In class we were putting papers into a little of water and observing what would happen. However on the papers we put a drawing or a mark in different colors and then take pictures.

Here are some design that came out of my designs:

We had to experiment with water and alcohol, the design I used was 2 dots of red pen and 1 of gray just a little above of the red dots. When I put it into the glass with water, after a few minutes the design I saw was:

Most polar: pink

Most non-polar or least polar : purple/gray (because it is not sticking to the paper so the water is dragging it up) 

Chemical compounds: water : 8

WE KNOW THAT POLAR THINGS ATTRACT TO POLAR AND NON-POLAR TO NON-POLAR. So the higher on the paper, the more non-polar.

Then I did the exact same drawing in a second paper and placed it in alcohol, however I noticed it took much longer for the alcohol to travel up the paper.

Alcohol is less polar than water, so the colors went up slower. However the polar and non-polar colors where the same as for the water. I find it pretty interesting that water can drag colors with itself just like that. 

And, I know that what we did was a chemical reaction, because when we placed some above a special lamp, they glowed (luminescence!).
