Simple Science Activities
Earth Cookies

These simple science activities demonstrate the major parts of the Earth. The Earth consists of the outer layer called the crust where we live. Below the crust is the mantle which is has the largest volume.

Near the center of the Earth the rocks melt and we have the liquid outer core. The inner core is solid rock. You will create these layers of the Earth with a cookie, frosting and cinnamon candy.
