Let's eats rocks!!!

Mrs. Ramsay told us we were going to make rocks and eat them. We were all really surprised and excited. On Thursday, we did a rock cycle simulation. We got to help her with the poject. So first,we had to get sediment (jumbo marshmallows) into a riverbed (flat pan). Do you know how sediment becomes sedimentary rock? Well this is how, minerals and sediment get pushed down with pressure and becomes sedimentary rock. WE got to come up and put lost of pressure on top of the layers of sediment. More and more layers of sediment came and created that pressure. The more pressure that is added the deeper a rock goes. That's when heat ios applied and it becomes a metamorphic rock. Minerals mix (chocolate chips, sugar, vanilla) into the rock as as the heat increases it becomes magma. Magma boils up and shoots out of the volcano. When magma exits it becomes lava. Lava is magma that is outside a volcano. Then it cooled and hardened and it became igneous rock. Those are the rocks that we ate. Yummy! 

You can make your own rocks at home too. Here are the incredients.
1 bag of chocolate chips
3 bags jumbo marshmallows
3 cups sugar
1 cup of vanilla
1 pan
1 mixing spoon
2 sticks of butter

We're sure you will enjoy eating rocks as much as we did.
