Rocks, Rocks and More Rocks

Continuing on with our study of the rock cycle, today we made edible rocks to demonstrate metamorphic, sedimentary and igneous rocks.

For the igneous rocks we took chocolate chips and melted them in the crockpot. Once the chips were melted, we scooped it out onto wax paper and allowed it to cool and harden just like igneous rocks.

For the sedimentary rocks we used graham crackers, then covered the graham cracker with icing, mixed in some sprinkles and added a swedish fish candy as a fossil. We repeated this process 2 more times and then stacked all of the layers together to create sedimentary rocks. 

Last but not least we created metamorphic rocks using Starburst. We started of with three different Starburst candies. We unwrapped them and put them into a baggie. We then used the heat and pressure of our hands to melt the Starbursts and morph them together. 

We really enjoyed learning, making and eating our new "rocks".
