Science- Crayon rocks
In science right know we are learning about rock. We are using crayons to speed up the process. We first weatherd the crayons by shredding them into sediment. Sediment is tiny rock pieces that have been broken down over thousands of years. Then we took it and put it in tin pouches and put them under weight, this kind of rock is called a sedimentary rocks. The reason they became rocks was because of the pressure we or the printer put on them the sediment got pushed together. My group put it under the printer in my school. After about a week we took them back to class and opened them my group had the biggest piece, and here it is.

This is an interesting experiment to see the process that generally takes a very long time to create. What other kinds of weights were used in your class? Did more weight help the rocks to hold together better? Do you think heat would help this process?

First i want to thank you for reading my blog. Some of the other weights were dictionaries and book shelves. The heavier the weight the more the rock formed. THe rock formed by the pressure so yes. We added heat for the two other experiment we did with te same thing for one we melted it completely and for the other we got it hot and put it under pressure. Those work and formed better rocks.
