Activity 1 - Differences between Rocks and Minerals
Basic definitions: Read and learn the following definitions.
Rock - A rock is any natural combination (aggregate) of two or more minerals. For example,
granite is a rock composed of the minerals quartz (white), feldspar (pink), and mica (black)
Rocks are classified into one of three groups depending on how they were formed:
igneous, sedimentary, or metamorphic.
What other rocks are you aware of? ___________________________________________
Mineral - A mineral is a naturally occurring, homogeneous (uniform), inorganic (non-living)
solid having a definite chemical composition, and a characteristic crystalline structure.
The five most abundant elements in the Earth’s crust are oxygen (O), silicon (Si),
aluminium (Al), iron (Fe), and calcium (Ca). For example, the mineral quartz is
composed of silicon and oxygen in a form known as silicon dioxide (SiO2).
What other minerals are you aware of? ________________________________________

Physical and Chemical Properties of Minerals
Property Characteristics
Crystal form e.g. cubic, hexagonal
Hardness - measured on Mohs’ scale 1 = talc, 2 = gypsum, 3 = calcite, 4 = fluorite,
5 = apatite, 6 = orthoclase/feldspar, 7 = quartz,
8 = topaz, 9 = corundum, 10 = diamond
Specific gravity The relative weight of a mineral compared to the weight of
an equal volume of water. Sulphur has a specific gravity of
only 2 grams per cm3
, pyrite (fool’s gold) has a specific
gravity of 5 g/ cm3
, whereas gold has a specific gravity of
19.3 g/cm3
Cleavage The way some minerals split along planes related to the
molecular structure of the mineral. For example, halite (salt)
cleaves into cubes.
Colour Must be used carefully as there are many variations in
colour for some minerals. Sulphur is a very distinctive
yellow.
Taste Quartz and halite look the same, but only halite will taste
like table salt.
Smell Some minerals give off a distinct odour. Sulphur smells like
a burnt match.
Feel Some minerals have a distinctive feel. Graphite feels soft
and slippery.
Streak Some minerals, when rubbed on unglazed porcelain, leave
behind a streak of colour. For example, hematite (usually a
grey or silvery mineral) will leave behind a reddish-brown
streak.
Lustre Lustre is a description of how light interacts with the surface
of a mineral. Some minerals look metallic, others resinous,
silky, glassy, or pearly.
Phosphorescence Ultraviolet (uv) light causes some minerals to get “excited)
and in turn emit light at a longer wavelength which we see
as colours. For example, the mineral fluorite looks clear or
slightly green under normal light but emits purple light
under exposure to uv.
Magnetism Some minerals such as magnetite and pyrrhotite are
attracted to a magnet.
Radioactivity Some minerals such as uranium emit radioactivity which can
be measured with an instrument called a Geiger counter.

Activity 6 - Making Sense of Igneous Rocks
Activity:
Pumice - Pumice is formed when lava, magma that reaches the surface of the Earth (extrusive), cools
quickly and solidifies (becomes volcanic rock). It is identified by its holes, called vesicles, which were
formed from gas bubbles trapped in the cooling lava after the volcanic eruption. If you look closely at
other volcanic igneous rocks, you will sometimes see vesicles, but usually not as clear as you will see in
this pumice sample.
1. Draw the sample of pumice.
2. Use the magnifying glass to examine the vesicles found on the sample. Describe what you see.
______________________________________________________________________________
3. Place the sample of pumice in the container of water and note what happens. Explain why this
happens. Remove the pumice from the container and place it on the paper towel.
______________________________________________________________________________
Diorite - Diorite is formed when magma cools slowly under (intrusive) the Earth’s surface (plutonic
igneous rock). It is identified by its large grain (crystals) size and its appearance. Diorite is made up of
about half light - and half dark-coloured grains. Each grain represents an individual mineral. The different
coloured grains indicate that there is more than one mineral in the sample. That is a clue that diorite is a
rock and not a mineral. The white mineral is plagioclase feldspar and the black is hornblende and mica.
4. Draw the sample of diorite.
5. Use the magnifying glass to examine the diorite. Describe what you see.
________________________________________________________________________
6. Place the diorite in the container of water and note what happens. Remove the rhyolite
from the container and place it on the paper towel.

Activity 7 - Making Sense of Sedimentary Rocks
Sedimentary rocks are formed from pieces of other rocks that have been eroded. A very
important feature of sedimentary rocks is grain size, which is how large the individual pieces are
that make up the whole rock.
Activity:
1. Look at the sediments in the jar. Observe the shape and colour of the grains. Use a ruler to
estimate the size of the grains (try counting the number of grains along 1cm).
Name Colour Shape Size
Sediment 1
Sediment 2
Sediment 3
2. Gently shake the jar of sediments and place the jar back on the table. Record your
observations of the water and sediments in your container after each time period listed.
Time Observations
Immediately after shaking
After 1 minute
After 5 minutes
After 10 minutes

Activity 8 - Making Sense of Metamorphic Rocks
Metamorphic rocks are formed when existing rocks are changed by being exposed to increased pressure
and/or heat. The process of metamorphism does not melt the rock, but instead transforms it into denser,
more compact, harder rock. Extreme heat allows the chemical components of the rock to recombine to
form new minerals. Pressure increases with increased depth and transforms the physical characteristics
of the rocks. Metamorphism often occurs when hot magma is intruded (forced) into cracks and fractures
in the surrounding igneous or sedimentary rocks - a process known as contact metamorphism. Some
metamorphic rocks like gneiss (say “nice”) exhibit colourful banding and striped appearance known as
foliation.
Activity - Part 1:
1. Roll the plasticine between your hands until it is soft and easy to shape. Roll it into a ball shape.
2. Insert the five pennies into the plasticine ball in different directions (randomly oriented). In the chart
below sketch and label a picture of the plasticine ball before pressure was applied.
3. Place the ball on the desk and carefully flatten the plasticine. In the chart below sketch and label a
picture of the plasticine ball after pressure was applied.
Before Pressure After Pressure
4. Remove the pennies from the plasticine ball and leave for the next group.
Activity - Part 2:
Complete the Venn diagram below to compare and contrast the parent rock - granite (igneous) with its
metamorphic form - gneiss. Note what is similar about the two rocks in the centre section, and what is
different about each in their respective sides.

The Stages of Operating a Mine
1. Mineral Exploration
Geologists use many different methods to look for valuable minerals. They study satellite
images of the Earth and use aircraft to measure things, such as the magnetism in the land. Maps
also help them choose an area to explore.
Before a mining company can explore more closely, it must get the exclusive rights to a
piece of land. This is called staking a claim. The company can then use special equipment to look
more closely for mineral deposits. Geologists do field work to identify different rocks and collect
rock and soil samples to study in a laboratory. If the results are good, the company drills holes in
the ground to take out long, thin cylinders of rock called cores, which can be studied to find out
how much valuable mineral they contain.
2. Evaluation
Once a mining company finds a mineral deposit, the next step is to decide if it will be
worth spending the millions of dollars needed to construct a mine.
A mineral evaluation looks at how much it will cost to construct and operate the mine, to
sell the minerals, to take care of the environment, and whether or not the company will make any
money. Finding a good mineral deposit is rare.
3. Mine Construction
Mineral deposits close to the surface of the Earth can be mined by digging a surface or
open pit mine. This means using huge diggers to scrape away the surface material and blasting
the solid rock with explosives to reach the valuable minerals.
Mineral deposits buried deep in the Earth have to be mined using an underground mine.
This means digging tunnels into the Earth to reach the valuable minerals.
4. Mine Operation and Mineral Processing
Actual mining can begin once the construction of the mine is complete. Miners use drills
and explosives to break up the rock and large scoops and machines to move the rock top the
processing plant.
Mined rock contains valuable minerals as well as worthless ones, all mixed together.
Processing separates out the valuable minerals from the waste. Usually, the rock is first crushed
into a fine powder. Then, a separation process captures the small amount of valuable minerals
from the large amount of powdered waste rock. Some minerals are refined to produce pure
metal in a process called smelting.
A mining company has to deal with the leftover waste materials called tailings, which are
rock fragments, dust, and chemicals. They must be stored in safe areas to avoid polluting the air
or water.
5. Mine Closure and Land Reclamation
No mine will last forever. When a mine closes, the mining company has to reclaim the land,
making it safe, usable, and a natural part of the surrounding environment. It must remove the
buildings, make sure mine waste doesn’t harm the environment, make any pits or tunnels safe,
and replant the land with grass and trees.
