    Cut your Play-Doh Earth model in half

    The seventh step is to cut the Earth in half so you can see all of the layers. I found it easiest to use a serrated knife and make small back and forth motions instead of cutting straight down, which just smudges the dough.

    Label the layers of your Play-Doh Earth model

    The final step is to label the model. I wrote the name of each layer (inner core outer core, mantle, and crust) on a piece of a note card and taped them to toothpicks which were then inserted into the Play-Doh.&nbsp;
