This is what we made in Science. What we did in Science is we were learning about sedimentary rocks, and how they are formed by a bunch of different things. Such as water, any kind of presure and many others, wind, erosion, ect. So our class decided to make our own sedimentary rocks.. Of coarse we can’t just use real rocks and wait a million years, so we went simpler and used crayons. Our class grined up the crayons into small small pieces and put the crayon shavings in a small bundle with fiol. Then we put it under something really heavy. Our group put our’s under out shelf  in the classroom. After a few weeks we got that bundle out from the shelf and looked to see if it turned into a so quote “rock” form the presure of that heavy shelf. The other groups had big chunks of crayon. Then we checked our’s thinging the same. The biggest piece of our experiment was about the size around 3 inches. maybe smaller. It wasn’t big at all…. but it was a fun project learning about sedimentary rocks.
