3. Record the value of your minerals ($1000 for
every gram in the cup): $____
Total profit = #3 – (#1 + #2)
Value of Minerals $_____ - Total Cost $_____
= Total Profit $_______
1. Total mining and processing fee ($100 per
every five minutes): $_____
2. Land damage: # of broken cookie pieces X
$100 = $_____
Total cost = #1 + #2
Total Land Damage + Chip Mine Fee: $______
Objective: Students will gain an
understanding of where minerals come from
and the environmental impact of mining.
For teacher: Stop watch, scale, bucket of pennies
For student: 4 chocolate cookies, toothpicks, pencil,
data recording sheet, small weigh boat
Mining for MMM…Mining for MMM…
1. Your mine will earn $1000 for every
gram of chips mined.
2. You will be charged $100 for every 5
minutes of mining.
3. You will be fined $100 for each piece of
cookie that breaks off. The more
damage, the more you lose.
Investigating the layer-
What is stratigraphy?
Study of sediment layers
and the relationship
between rocks and
fossils with time.
Rules of StratigraphyRules of Stratigraphy
• Steno’s Principle of Superposition
Lower layers are older than higher layers
• Original Horizontality
Layers are deposited in (near-) horizontal
• Principle of Lateral continuity
Layers extend laterally in all direction
• Cross-Cutting Relationships
Layers intruded by other rocks are older than the
represents a gap in
deposition – lost

……..And Moved..And Moved
Faults - Surfaces where rocks have fractured and
been displaced (move relative to one another).

Given the diagram, list the order (oldest to youngest) in
which the following events happened:
A. Faulting B. Tilting E. Intrusion
C. Erosion D. Deposition
