Write a paragraph about your item. Some ideas of information to include are: Is it old or new? What species is it from or what is its classification? Why is it important? What is its role in nature?: I believe what I found is sandstone, I think it is sandstone because when I rubbed it with my hand sand came off. The stone must have been old because there was other people’ s names carved into it, but people do not make the stone so I do not know how old it is. It could be thousands of years old.I did some research on it and it was called St. Peter Sandstone! I also learned that the sandstone was laid in a inland sea millions of years ago. So it is over thousands of years old!
What makes it interesting to you? Why did you choose this item?: I chose this item because sandstone is very cool. I liked it because it is all sand pushed together, so when you rub it sand come right off!
