Chocolate Rock Cycle - 1 views

egenteman on 27 Jan 15This activity is a great introduction or addition to learning about the rock cycle. By using chocolate, you can show students the difference between weathered, heated, cooled, and compressed rock. The students can use bars of chocolate to create "sedimentary," "metamorphic," and "igneous" chocolate. This is a simple way to effectively show students the difference between the types of rock. The hands-on approach will aid in the students seeing firsthand what the differences look like. It aligns with NGSS focused on the rock formation and cycle, as well as, the geosphere.

mbberkbuegler on 29 Jan 15How sweet is this activity? It's an introduction to the rock cycle using chocolate! Chocolate can be ground into small particles (weathered), heated, cooled, and compressed - just like rocks. Unlike rocks, chocolate can undergo these processes safely and at reasonable temperatures. Use your chocolate to create "sedimentary," "metamorphic," and "igneous" chocolate. I chose this lesson because it is a great way to get the class focused during a not so exciting topic, not to mention chocolate is my favorite thing on the entire world. I think the chocolate creations are perfect representations of the changing rock, and would allow students to understand the rock changing process easily by using visuals. I would introduce this lesson in an earth science unit as a good tool to show the three stages of rock, and to get the class hooked and ready to discuss the different phases. I would also enjoy making these three phases at home because I am sure there would be lots of left overs!
