Title: Mock Rock Lab
Date: November 7, 2011
Teachers: Mr. Sheng & Mrs. Myers
Lab Partner: Lily Cinquanto

Lab Question/Problem: What are the properties a geologist might use to describe rocks?

Hypothesis: If I break down the rock, then I will be able to find out what it is made of.

Materials: Mock Rock, gloves, safety goggles, hand lens, tape measure, triple beam balance, vials, water, paper clip, plate, nail, digital microscopes, visual microscopes.

-Describe the rock in detail.
-Make surface observations.
-Sketch or trace the rock and write observations.
-Make magnified observations.
-Draw a magnified view of a small part of your rock.
-Measure the diameter (the distance across)
-Measure the circumference (the distance around)
-Measure the depth (the thickness)
-Measure the mass
-Break rock into pieces, use picks to break the rocks apart and separate into the different ingredients sorting them into piles.
-After sorting, write observations of each pile.

Observations: The Mock Rock feels bumpy, it has a flat surface, it has a mostly pinkish white color with circular red and green dots that look like nerds candies, it looks like it has crystals, it has cracks, it is sparkly, it has very tiny craters, the shells inside the rock are easy to break.
Surface observations - It has a flat surface on the bottom and it has a bumpy surface on the top.
Magnified observations -It looks like it has mini craters, it has blemishes, the shells look like they have wavy lines, can see red & green dots that look like the candy nerds.

Diameter (long) -10 cm.
Diameter (short) - 8 cm.
Circumference - 23 cm.
Depth - 1 cm.
Mass - 73 grams
Observations of piles - It has circular red & green dots, the shells break apart easily, the sand has a pinkish color, you cannot see the crystals anymore, got harder to cut overnight.
Dissecting microscope observations - It has red & green dots, shells and looks dirty.
Digital microscope observations -It is easier to see close up, looks foggy looks like an x- ray photo, you can see inside of shells and sand.
Vial observations -Looks like sand from the sea, grayish & yellowish color, water is sort of foggy, it looks like it is bubbling.
Evaporating dish observations -Looks like dried sand, looks nothing like it used to look, looks like one big giant visible germ.

Conclusion: I think the ingredients in the Mock Rock are: sand, water, salt, food dye, minerals, crystals, rock shavings, salt, sugar, shells, and clay.
