So, for my science project, I decided to use chocolate chips to simulate the rock cycle. I started off with three different types of chocolate chips: regular chocolate, white chocolate, and butterscotch chips. These chips were going to act as my "rocks" throughout the experiment.
First, I placed five of each chip into separate baggies. I wanted to weather these rocks, just like how rocks in nature undergo erosion. I gently smashed the chips with a hammer, breaking them into small pieces. This created sediments, which are like tiny rock fragments.
Next, I moved all the chips to the lower corner of the baggie to represent deposition, where sediments are deposited in a certain area. Then, I created sedimentary rock by squeezing the baggies of chips in my hand for a few minutes. The pressure and heat caused by my hand caused the sediments to stick together, forming solid sedimentary rocks.
For metamorphic rock formation, I put the rock sediments from the second baggie inside the bend of my knee. By folding my knee over the baggie, I applied pressure and heat for around 8-10 minutes. This caused the chocolate chips to melt and fuse together, just like how extreme pressure and heat can change rocks in nature. The metamorphic rocks changed shape and became more compact.
Lastly, I created igneous rocks by placing the rock sediments from the third baggie inside the bend of my knee again. This time, I folded my knee over the baggie for around 10-15 minutes until the chocolate chips melted into a liquid. This represented magma, which is molten rock beneath the Earth's surface. I then cooled the molten chocolate by either placing the baggie on the counter (intrusive igneous rock) or on a pan filled with ice (extrusive igneous rock).
After these processes, I carefully removed the rocks from the baggies and observed their different forms. The sedimentary rock appeared to be layered, as the sediments had stuck together. The metamorphic rock had a more solid and compact appearance, as the melted chocolate had cooled and hardened. The igneous rock, whether intrusive or extrusive, had a smooth and solid texture, as the melted chocolate had solidified again.
Overall, I noticed that temperature and pressure played a significant role in transforming the chocolate chips into different types of rocks. The hotter and more pressure applied, the more the chips melted and transformed. It was fascinating to see how applying different conditions could change chocolate chips into rocks with various physical appearances.
do the following project following these steps of taking different types of choclate chips and taking them through the rock cycle having the choclate chips act like rocks:
- have three choclate chips that will act as rocks (choclate chip, white choclate chip, and butterscotch chips)
-place 5 of each chip into a baggie
-weather the rocks by gentlysmashing it with a hammer. it will create sediments by breaking them into peices.
- once the sediments have formed, move all the chips into the lower corner of the baggie. the movement represents deposition.
- create sedimentary rock with the work sediments in the first baggie. squeeze the rocks inside the baggie in your hand for 3-5 minutes. when the pressure and heat have been strong enough, the sediments will stick together and form sedimentary rock.
- create metamorphic rock with the rock sediments in the second baggie. place the choclate into the baggie inside the bend on the underside of your knee. fold your knee over the sediment and keep it pressed together for 8-10 minutes until the rock changes shape (it melts together)
create igneous rock with the rock sediment in the third baggie. place the choclate in the baggie inside the bend of the underside of your knee. fold your knee over the sediments for 10-15 minutes until the rock (choclate) has melted into a liquid. this represents magma. once it's a liquid you may place it on the counter (still in the baggie) to cool (intrusive igneous rock) or you may place it on a pan filed with ice to cool (extrusive igneous rock)
- one your rocks have formed, remove them from the baggie.
- Now, write a meduim sized paragraph about your observations of the different forms of rock. discuss the physicak appearance of each type of rock and how temperature and pressure affected the different types of rock. Important: make it sound very human, at the pov of a thirteen-year-old student in a 7th grade writing level.
