Igneous rock forms from hot,
melted lava that cools and hardens into a
rock. To simulate this, we melted chocolate
chips and then put a "dollop" on wax paper.
We smoothed it out under the wax paper and
then put it in the freezer. When it came
out, it was solidified into another shape!
Metamorphic rock forms when
two or more types of rock merge together
from pressure over time, as well as heat. To
simulate this, each student received a piece
of white bread and a piece of wheat bread.
Using their fists to pound them, and rolling
pins to merge them, students were able to
combine the two "rocks" into one new flat
Sedimentary rock forms when
layers of "sediment" merge through time from
pressure and heat. To simulate the layers,
we first put down a layer of cookie dough in
a pan. Then we added layers of chocolate
chips, M&Ms, raisins, white chocolate
chunks, and sprinkles!!! To represent the
"heat" we baked it and out came a delicious
