Title: Mock Rock Lab, December 5,2011 Mr. Sheng and Mrs. . Lab partner, Madison Ott


Lab Question/Problem:

What are the properties a Geologist might use to describe a Mock Rock?

Hypothesis:

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

Materials:

Safety goggles, gloves, hand lens, measuring tape, triple beam balance, two picks, water, mock rock, paper clip, paper plate.

Procedure:

Describe the rock in detail.
The rock has tiny green and red gems on it. The weight is like a golf ball. Its texture is medium. It is hard yet, it can be broken with a pick.

-Make surface observations.
The surface looks sandy in color such as light brown. It feels bumpy and smooth together like sandpaper.

- Sketch or trace the rock and write observations.
The rock texture is medium. It is hard and be broken with pick. It is light weight like a golf ball. It is light brown in color. The rock has a circle shape with bumpy sides.

-Make magnified observations.
The rock looks like it is made of sand. The rock is solid. I can see the little grains of sand. It is shaped like a circle with bumpy edges and thick in the middle.

-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: Include the above observations and measurements, plus the observations of the vials, any digital and/or dissecting microscope observations, and evaporated blister slide observations.
