Raw Data/Final Data/Graphs

Graphs:

These are the mechanical weathering graphs showing the difference in the rock’s weights over a four day period:

These are the chemical weathering graphs showing the pH level at the start of the day and the comparison of rock weights:

Tables:

This is the mechanical weathering table showing the data collected over a four day period of each rocks weight:

Dates	Limestone	Sandstone	Shale	Granite
4/4/16	18	17	16	16
4/5/16	1	16	16	15
4/6/16	15	16	16	14.5
4/7/16	15	16	16	14.5

These are the chemical weathering tables showing the pH level at the start of the day and the rock weight comparisons:

Rock Weight – Chemical Weathering (grams)	3/26/2016	4/8/2016
Limestone	22	8
Granite	12	10
Sandstone	22	22
Shale	6	4
