Types of Rock (A Chocolate Experiment)

Procedures For Sedimentary Rocks: Using all the materials (nips, sprinkles, dark and white chocolate, biscuits), place it one by one on a separate aluminum foil.

2. Fold the aluminum foil and press it until all the materials are crashed. 3. Put it on a clean aluminum and place it layer by layer.

4. Fold the aluminum foil over the top. 5 4. Fold the aluminum foil over the top. 5. Push down hard with palm until all the ingredients feels like it has stuck together.

6. After pushing, slice the side of the output to reveal the layer.

Reflection The process of crashing the sprinkles and nips should have been taken into account to represent the erosion and the weathering process of forming the rock. Erosion- destructive forces are constantly breaking up and wearing away the rocks of the Earth. These forces include: grinding ice, waves, rain, and heat. Erosion occurs when these agents loosen and carry away the fragments of rock or once living things somewhere else (1).

. . . Weathering- breaking down or dissolving of rocks and minerals on Earths surface. Water, ice, acids, salt, plants, animals, and changes in temperature are all agents of weathering (2). The biscuit should serve as component for the cementation process. Cementation- hardening and welding of clastic sediments (those formed from preexisting rock fragments) by the precipitation of mineral matter in the pore spaces. It is the last stage in the formation of a sedimentary rock (3).

For Metamorphic Rocks: 1. Using the dark and white chocolates, put it on the aluminum foil. 2. Fold the foil and squeeze it into a sphere. And then unwrap it.

3. Then put it in an aluminum foil boat to make it float above the hot water. 4. Do not melt it.

5. Allow it to cool for a minute.

reflection The chocolate should be flatten first and then heat it before squeezing it to form rock to be able to heat all parts of the rock.

For Igneous Rocks: 1. Use the sedimentary rock output. 2 For Igneous Rocks: 1. Use the sedimentary rock output. 2. Put it in an aluminum foil boat.

3. Put it above the hot water and make it melt totally. 4. Lastly, let it cool.

REFLECTION It is easy to use only the dark and white chocolate in forming igneous rocks because it will melt easily, unlike the nips and sprinkles it would take a large amount of time to melt.
