1.HOW WELL YOU READ ANDFOLLOW DIRECTIONS!!

2. YOUR ABILITY TO USE THE EARTH SCIENCE REFERENCE

TABLES

3. YOUR SKILL, KNOWLEDGE, and ACCURACY IN PERFORMING

EARTH SCIENCE PROCEDURES

IMPORTANT LAB SKILLS YOU NEED FOR THE REGENTS

EXAM

1.IDENTIFICATION OF ONE MINERAL AND CLASSIFICATION OF TWO ROCKS

2.LOCATING AN EARTHQUAKE EPICENTER

3.CONSTRUCTING AND ANALYZING AN ELLIPTICAL ORBIT

THREE LAB STATIONS9 mins. each

1.Luster: metallic or non-metallic

2. Cleavage or Fracture: cleavage/even or fracture/uneven

surfaces

3. Streak: Color or Colorless or white (white ceramic plate)

4. Hardness: Soft or Hard (glass plate)

Mineral Identification

Rock Classification – Use ESRT charts1.Igneous –CRYSTALS (extrusive/small crystals) (intrusive/large crystals)

2. Sedimentary – SEDIMENTS (fossils, shells, sand, dry mud, pebbles)

3. Metamorphic – CRYSTALS (banding/black & white crystals in alternating layers) or (nonfoliated distorted crystals that are one color)

Do NOTNOT give the name or color of the rock!!!!

Locating an Earthquake Epicenter1. Subtract the difference between the

P wave and S wave.2. Use ESRT to determine the distance.

3. Use the distance scale and compass to draw the circle.

4. Mark “x” where 3 circles intersect (epicenter).

USE INDEX CARD TO MARK OFF THE DIFFERENCE IN ARRIVAL TIME

Line your compass up to the EXACT distance on

the scale. Use the metric side (cm) beginning from

zero.

Constructing and Analyzing an Elliptical Orbit

Measure the distance between foci to the nearest tenth.

Measure the length of the major axis to the nearest tenth.

Use formula and calculate eccentricity to the nearestone-thousandth (example: 0.234) (do NOT include unit)!

*MORE elliptical = GREATER ECCENTRICITY (higher value)*LESS elliptical = LESS ECCENTRICITY (lower value)

MARK AN “s” ON ONE FOCUS WHERE THE SUN ISMARK AN “x” ON ELLIPSE LINE WHERE GREATEST ORBITAL VELOCITY IS

READ AND FOLLOW ALL DIRECTIONS

EXACTLY

BEFORE

YOU DO ANYTHING!!!
