1. 1.HOW WELL YOU READ AND FOLLOW 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

2. 1.IDENTIFICATION OF ONE MINERAL AND CLASSIFICATION OF TWO ROCKS 2.LOCATING AN EARTHQUAKE EPICENTER 3.CONSTRUCTING AND ANALYZING AN ELLIPTICAL ORBIT THREE LAB STATIONS 9 mins. each

3. 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 charts 1.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) NOT Do NOT give the name or color of the rock!!!!

4. Locating an Earthquake Epicenter 1. 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).

5. USE INDEX CARD TO MARK OFF THE DIFFERENCE IN ARRIVAL TIME 2800 km 4:10

6. Recording the difference in arrival time: San Francisco: 4:102,800 km 1,000 2,0003,0004,0005,000 Line your compass up to the EXACT distance on the scale. Use the metric side (cm) beginning from zero. 0

7. 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 nearest one-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 IS MARK AN “x” ON ELLIPSE LINE WHERE GREATEST ORBITAL VELOCITY IS

8. READ AND FOLLOW ALL DIRECTIONS EXACTLY BEFORE YOU DO ANYTHING!!!
