Rocks & Minerals Rocks are composed of one or more minerals. The colour of the rock is
influenced by the minerals it contains. Minerals are naturally occurring material with a definitive chemical
composition
NaAlSi3O8 – CaAl2Si2O8
KAlSi3O8
SiO2
K(Mg,Fe)3(AlSi3O10)(F,OH)2

Rocks & Minerals Hardness: Mohs scale
Glass has a hardness of 5.5 If a mineral scratches glass
then its hardness is greater than 5.5.
If glass scratches it, its hardness is less than 5.5.
Other properties of Minerals Parting/Cleavage Fracture Streak Crystal Habit Density Magnetic

Exercise
Organize into groups Each group shall be presented with some rock samples Separate the rocks into 2 groups
Sedimentary Non-sedimentary (Igneous/Metamorphic)
Enumerate the properties of the sedimentary rocks in the provided identification form
Use the Sedimentary Rock identification workflow to name the rock (Please bring a printout of the workflow to class)

Assessment
Individual Assessment Each shall be provided with 3 sedimentary rocks Tasks
List the physical properties in the provided answer sheet. Estimate the porosity (apply drops of water to check if it is being
absorbed by the sample) Using the Sedimentary Rock Identification Workflow, name the
rock
