Regents Review Lab Practical
Station 1: Finding an
Earthquake's Epicenter
● Step 1:
○ Find the difference in Arrival
times for the P and S wave
Station 2: Identifying
2 Rocks and 1 Mineral
Rock Type Classification:
● Igneous Rock
○ Intergrown Crystals
○ Glassy Texture
○ Vesicular Texture
■
● Step 2:
○ Use the difference to
determine the distance to the
epicenter on ESRT p. 11
Gas pockets
● Sedimentary Rock
○ Contains Fossils
○ Clastic Texture
■
Pieces of rock cemented
together
Station 3: Elliptical Orbits
and Eccentricity
● Step 1:
○ Use the string
and pins to
construct an
ellipse
● Step 2:
○ Mark one of your foci with an
“S” for the Sun
○ Place an “X” where orbital
velocity is the greatest.
○ Bioclastic Texture
■
Shell pieces cemented
together
● Metamorphic Rock
○ Foliated Texture
■
■
Wavy distortedlLayers
Banding
● Step 3:
○ Use a metric ruler (cm) to
find distance between foci
Mineral Identification:
● Step 3:
○ Use a compass and the
scale provided to draw a
circle around City B
● Step 4:
○ Repeat steps 1-3 for City 3
● Step 5:
○ Mark the epicenter
■ Place an X where all three
circles intersect
● Luster: How light reflects
■ Metallic:
●
Silver or Gold
■ Nonmetallic
● Glassy, Earthy/Dull
● Cleavage or Fracture
○ Cleavage= Flat breaking
● Step 4:
○ Use a metric ruler (cm) to
find the length of the major
axis
■ Smooth/ Flat Surface
○ Fracture= Uneven breaking
■ Jagged/rough surface
● Streak: Ceramic Tile Test
○ Color
○ Colorless or white
● Step 5:
○ Calculate the eccentricity
using this formula (no units)
● Hardness: Scratch Test
○ Scratches Glass= Hard
○ Doesn’t Scratch Glass= Soft
*Plug this info into the Flow Chart to
identify the mineral*
● Step 6:
○ Compare your eccentricity #
to the eccentricity of the
planet given.
■ Write this →
● “The greater the
eccentricity the more
eccentric the orbit”
